This hides the need to provide mutable C strings, and unifies
existing basename calls and variations in a single location.

memory.h shadows a system header which normally isn't a problem
because of the include paths in Breakpad, but the Firefox build
system winds up with src/common in the include path so we've had
a workaround for this for years. Renaming the file lets us get
rid of that workaround and shouldn't hurt anything.

The Rust compiler uses GCC C++ name mangling, but it has another layer of
encoding so abi::cxa_demangle doesn't produce great results. This patch
changes dump_syms to dump unmangled names by default so that consumers can
demangle them after-the-fact.
It also adds a tiny bit of support for linking against a Rust library I wrote
that can demangle Rust symbols nicely:

Doing a `make -jN check` from a fresh build breaks (and has probably been
broken for a while). linux_client_unittest_shlib is missing $(TEST_LIBS)
from its _DEPENDENCIES. The automake manual says if _DEPENDENCIES are not
specified they'll be computed from _LDADD, but we are specifying it and just
leaving out $(TEST_LIBS).

This preserves full build ids in minidumps, which are useful for
tracking down the right version of system libraries from Linux
distributions.
The default build id produced by GNU binutils' ld is a 160-bit SHA-1
hash of some parts of the binary, which is exactly 20 bytes:
https://sourceware.org/binutils/docs-2.26/ld/Options.html#index-g_t_002d_002dbuild_002did-292
The bulk of the changes here are to change the signatures of the
FileID methods to use a wasteful_vector instead of raw pointers, since
build ids can be of arbitrary length.
The previous change that added support for this in the processor code
preserved the return value of `Minidump::debug_identifier()` as the
current `GUID+age` treatment for backwards-compatibility, and exposed
the full build id from `Minidump::code_identifier()`, which was
previously stubbed out for Linux dumps. This change keeps the debug ID
in the `dump_syms` output the same to match.

The dump_syms_mac tool only works for the system it is being built for
(it doesn't support running on ELFs for a diff target), and it builds
only for x86 currently.
If you look at the mac header:
src/third_party/mac_headers/mach/machine/vm_types.h
it will #error for non x86/arm systems, and the arm header is not in
our source tree.
Tweak the build so it's only compiled when targetting x86 systems.

The current makefile ends up building ~17 copies of the gtest/gmock
objects -- every test that refers to the cc files directly will have
its own copy. This is because the build doesn't know if CFLAGS and
such have changed between each target (and in some cases, they are).
Create a new libtesting.a target to hold a single copy of these files
and update all of the unittests to link that in. This speeds up the
build a bit especially when you aren't using ccache.
This does mean we can no longer build gtest/gmock with unique flags,
but we haven't wanted that so far, so clearly no one wants that.

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.

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.

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.
BUG=NONE

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.
