This CL exports LinuxCoreDumper and ElfCoreDump in the client library. The ARC collector, which is an alternative to core2md optimized for large core dumps, needs these symbols for core dump parsing and conversion to minidump.

libbreakpad.a pointlessly contains libdisasm.a
This looks like a left-over from when libtool was used
Since this has no useful effect (as the linker doesn't recursively search
archive members which aren't objects), anything which requires the objects in
libdisasm.a must already be linking with it, so simply remove it.

Automake did not install headers under c/l/dwc, which caused
compile errors when building against an installed breakpad, since
other headers (e.g. client/linux/handler/exception_handler.h)
depended on it. This commit adds these headers to the list of
automake installed files.

Minor followup to crrev.com/1357773004 and
crrev.com/1361993002 which moved the README and forgot
to update the automake files.
This is to make "./configure && make" work.

We're working on building our Firefox Mac builds as a Linux cross-compile
(https://bugzilla.mozilla.org/show_bug.cgi?id=921040) and we need symbol
dumping to work. This change ports the Mac dump_syms tool to build and work
on Linux. I've tested it and it produces identical output to running the
tool on Mac.
The bulk of the work here was converting src/common/mac/dump_syms.mm and
src/tools/mac/dump_syms/dump_syms_tool.mm from ObjC++ to C++ and removing
their use of Foundation classes in favor of standard C/C++.
This won't compile out-of-the-box on Linux, it requires some Mac system
headers that are not included in this patch. I have those tentatively in
a separate patch to land in Gecko
(http://hg.mozilla.org/users/tmielczarek_mozilla.com/mc/rev/5fb8da23c83c),
but I wasn't sure if you'd be interested in having them in the Breakpad tree.
We could almost certainly pare down the set of headers included there, I
didn't spend too much time trying to minimize them (we primarily just need
the Mach-O structs and a few associated bits).
I just realized that this patch is missing updating the XCode project files
(ugh). I'll fix that up in a bit.

The PopSeccompStackFrame was introduced to deal with stack frames
originated in the legacy seccomp sandbox. The only user of that
sandbox was Google Chrome, but the legacy sandbox has been
deprecated in 2013 (crrev.com/1290643003) in favor of the new
bpf sandbox.
Removing this dead code as it has some small bound checking bug
which causes occasional crashes in WebView (which are totally
unrelated to the sandbox).
Note: this will require a corresponding change in the chromium
GYP/GN build files to roll.

when checking exploitability rating.
Linux minidumps do not support MD_MEMORY_INFO_LIST_STREAM, meaning the
processor cannot retrieve its memory mappings. However, it has its own
stream, MD_LINUX_MAPS, which contains memory mappings specific to Linux
(it contains the contents of /proc/self/maps). This CL allows the minidump
to gather information from the memory mappings for Linux minidumps.
In addition, exploitability rating for Linux dumps now use memory mappings
instead of checking the ELF headers of binaries. The basis for the change
is that checking the ELF headers requires the minidumps to store the memory
from the ELF headers, while the memory mapping data is already present,
meaning the size of a minidump will be unchanged.
As a result, of removing ELF header analysis, two unit tests have been removed.
Arguably, the cases that those unit tests check do not merit a high
exploitability rating and do not warrant a solid conclusion that was given
earlier.

ACCESS_VIOLATION and IN_PAGE_ERROR both specify
read/write/dep flags and address. ACCESS_VIOLATION currently
reports these, but IN_PAGE_ERROR does not. This change makes
IN_PAGE_ERROR report this information as well, and also the
additional NTSTATUS value for the underlying cause.

This introduces the microdump_stackwalk binary which takes advantage
of the MicrodumpProcessor to symbolize microdumps.
Its operation is identical to the one of minidump_stackwalk.
This CL, in fact, is also refactoring most of the common bits into
stackwalk_common.

Microdumps are a very lightweight variant of minidumps. They are meant
to dump a minimal crash report on the system log (logcat on Android),
containing only the state of the crashing thread.
This is to deal with cases where the user has opted out from crash
uploading but we still want to generate meaningful information on the
device to pull a stacktrace for development purposes.
Conversely to conventional stack traces (e.g. the one generated by
Android's debuggerd or Chromium's base::stacktrace) microdumps do NOT
require unwind tables to be present in the target binary. This allows
to save precious binary size (~1.5 MB for Chrome on Arm, ~10 MB on
arm64).

This change is a pure refactoring of the common bits of minidump_writer.cc
that will be shared soon with the upcoming microdump_writer.cc.
In particular, this CL is extracting the following classes:
- ThreadInfo: handles the state of the threads in the crashing process.
- RawContextCPU: typedef for arch-specific CPU context structure.
- UContextReader: Fills out a dump RawContextCPU structure from the
ucontext struct provided by the kernel (arch-dependent).
- SeccompUnwinder: cleans out the stack frames of the Seccomp sandbox
on the supported architectures.
- MappingInfo: handles information about mappings

- src/common/android/testing/mkdtemp.h:
Fixes a compilation error when using the (recent) NDK r9b,
see comments in the source file for details.
- android/test-driver, Makefile.am, Makefile.in:
Autotools 1.12 changed the way tests are run during "make check"
so add a new "custom test driver" to run tests on Android, and
modify Makefile.am / Makefile.in accordingly. Otherwise,
'make check' tried to run the tests on the host.
- android/test-shell.sh:
Allow several tests to run in parallel on the device, by
creating a custom test directory for each test process.
This allows running "make check -j8" reliably.
- src/common/linux/file_id_unittest.cc:
Disable the SelfStrip test on Android, since it assumes a 'strip'
executable is available on the target system where the test runs.

This patch fixes the build for Android on MIPS when
using the latest official Android NDK (r9):
- Update src/common/android/include/elf.h to add a missing
definition for SHT_MIPS_DWARF.
- Add src/common/android/include/sgidefs.h required by LSS
when compiling for MIPS.
- Update android/run-checks.sh to work properly with
the --abi=mips option. All tests were passed succesfully
with an emulator system image running Android 4.2.
- Update other Android-specific files.

This patch improves several things for Linux/ARM:
- Better detection of the number of CPUs on the target
device. The content of /proc/cpuinfo only matches the
number of "online" CPUs, which varies over time with
recent Android devices.
- Reconstruct the CPUID and ELF hwcaps values from
/proc/cpuinfo, this is useful to better identify
target devices in minidumps.
- Make minidump_dump display the new information
in useful ways.
- Write a small helper class to parse /proc/cpuinfo
and also use it for x86/64.
- Write a small helper class to parse sysfds cpu lists.
- Add a my_memchr() implementation.
- Add unit tests.
Tested on a Nexus S (1 CPU), Galaxy Nexus (2 CPUs)
and a Nexus 4 (4 CPUs).

- One of the unit test binaries refused to link due to
missing linker flags.
- The WriteDSODebug() function now works on Android, so
do not special-case it anymore.
- Ensure android/run-checks.sh will complain properly if
the client unit test suite fails on Android. It used to
consider that such failures were acceptable. Note that
it still considers failures when running the tools and
processor test suite on the device normal (fixing this
is a lot harder, and these parts of Breakpad typically
never run on a device, but on the host).

This adds a minimalistic implementation of getcontext()
for Android/ARM and Android/x86. The provided code is
in assembly and only implements the bare minimum required
by Breakpad to get the current processor state.
Note that:
- The FPU state is not saved to the ucontext_t on ARM.
(that's actually the main difference with a normal
getcontext() implementation).
This is normal. On Linux/ARM, such state must be
obtained with PTRACE_GETVFPREGS instead. This will
be implemented in a future patch.
- On x86, only the 'regular' FPU state is saved, to
mimic the GLibc/i386 implementation. The state of
SSE/SSE2/etc registers is not part of the upstream
getcontext() implementation.

This patch allows 'make check' to work when performing
an Automake-based build of Breakpad for Android. This
requires to have an Android device connected, and the
'adb' tool in your path.
You can test that with something like:
configure --host=arm-linux-androideabi
make check
This is achieved by adding a new small shell script
under android/test-shell.sh, which is invoked by the
Makefile (see TESTS_ENVIRONMENT definition in
Makefile.am).
By default, this runs all unit tests, including those
for the processor and tools (which normally never run
on an Android device).
Note that the test suites fails (e.g. 11 failing tests
for the client library). This will be addressed in later
patches.
+ Modify android/run-checks.sh to run the client library
test suite on the device by default.
+ Add a new option (--all-tests) to android/run-checks.sh
which forces it to run the unit test suite for the host
binaries, and the full suite on the Android device.
+ Update README.ANDROID appropriately.

This patch contains the source-related fixes to ensure that
the Breakpad unit tests build properly when targetting Android.
Calling 'make check' still fails because there is still no
way to run the unit test programs on a device. This will be
addressed by a future patch.
Important notes:
- You must target Android API level 9 (Gingerbread) or higher
to build the unit tests. This requirement is due to the
current GTest revision used in the breakpad source tree.
- This patch adds headers providing inlined C library functions
missing from the NDK (see src/common/android/testing). They
are inlined to avoid modifying Makefile.am and other build
files.
- Similarly, the <wchar.h> header-fix under
src/common/android/testing/include is only required by
GTest's current revision. E.g. it's not needed when building
Breakpad as part of Chromium which uses a more up-to-date
revision.

This patch remove many Android-specific #ifdefs from the Breakpad
source code. This is achieved by providing "fixed-up" platform
headers (e.g. <signal.h> or <sys/user,h>), in the new directory
src/common/android/include/, which masks differences between
the NDK and GLibc headers.
The old "android_link.h" and "android_ucontext.h" are moved
and renamed.
This also requires putting this directory as the first
include path during Android-hosted builds, hence the
modification of Makefile.am and configure.ac

http://breakpad.appspot.com/411002/, since revision 1001 only contains the new src/client/linux/linux_libc_support.cc and none of the other required files.
I'm not sure what happened, but I'm re-uploading the patch has another issue.

r945 introduced src/client/linux/log/log.c, which is used in
exception_handler.cc, and thus should be added as a dependency
in the linux_client_unittest target.
TEST=Compile and run unit tests on Linux.

This is really incomplete --- it's just what's needed to get started
testing support for the DWARF 4 attribute forms.

This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.
Specifically, this patch makes the following changes:
1. Turn the LinuxDumper class into a base class and move ptrace related
code into a new derived class, LinuxPtraceDumper.
2. Add a LinuxCoreDumper class, which is derived from LinuxDumper, to
extract information from a crashed process via a core dump file instead
of ptrace.
3. Add a WriteMinidumpFromCore function to
src/client/linux/minidump_writer/minidump_writer.h,
which uses LinuxCoreDumper to extract information from a core dump file.
4. Add a core2md utility, which simply wraps WriteMinidumpFromCore, for
converting a core dump to a minidump.
BUG=455
TEST=Tested the following:
1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6.
2. Build on Mac OS X 10.6.8 with gcc 4.2 and clang 3.0 (with latest gmock).
3. All unit tests pass.
4. Run Chromium OS tests to test core2md.
