This patch is taken from the downstream version of breakpad in
Chromium OS: https://gerrit.chromium.org/gerrit/15148
LinuxCoreDumperTest previously assumes the proc files of the child
process created by CrashGenerator::CreateChildCrash() have the same
content as its parent process, which may not be true. This CL modifies
CrashGenerator to copy the proc files of the child process, created by
CreateChildCrash(), before crashing that process.

it's deprecated. Apple marked bootstrap_register as deprecated on 10.5 but
it's actually still needed on that OS release. There isn't a way to get the
functionality Breakpad needs from it without calling it until 10.6.

This patch allows Breakpad's DWARF reader to at least read or skip
attributes using the new forms defined in version 4 of the DWARF
specification, instead of crashing.
Attributes encoded using DW_FORM_flag_present, DW_FORM_sec_offset, and
DW_FORM_exprloc should work fine now. However, compilation units using
DW_FORM_ref_sig8 to refer to types in .debug_types will need further work
to support. (GCC 4.6.2 does not emit .debug_types sections.)
Specifically:
- dwarf2reader::DwarfForm gets new values.
- dwarf2reader::Dwarf2Handler and dwarf2reader::DIEHandler get new handler
methods, named ProcessAttributeSignature, for DW_FORM_ref_sig8 attributes.
- dwarf2reader::CompilationUnit reads DW_FORM_ref_sig8 attributes, and
passes them to ProcessAttributeSignature. It also gets support for
DW_FORM_sec_offset, DW_FORM_exprloc, and DW_FORM_flag_present, using the
existing appropriate ProcessAttribute* methods.
- dwarf2reader::DIEDispatcher passes through ProcessAttributeSignature
attributes to its DIEHandler.
- Unit tests are updated.

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.

This patch is part of a bigger patch that helps merging the breakpad code

Specifically, this patch makes the following changes:
1. Add two convenient methods, back() and empty(), to the wasteful_vector
class.
2. Refactor the LinuxDumper class such that it can later be splitted into
a base class and two derived classes, one uses the current ptrace
implementation and one uses a core file.
3. Refactor the MinidumpWriter class such that it can later use different
derived implementations of LinuxDumper.

This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.
The MemoryRange class was added in r895 (http://breakpad.appspot.com/332001),
which is largely based on MMappedRange but generalized to be used in other
code. However, MemoryRange does not support minidump data structures. This
patch adds a MinidumpMemoryRange class that extends MemoryRange to handle
minidump data structures, which can then replace MMappedRange.
As with MemoryRange, MinidumpMemoryRange is unit tested.

3. All unit tests pass.

This function already establishes that (signed) i must be positive by the time
it assigns it to (unsigned) reg. Because reg is unsigned, it is impossible for
it to be negative. Because i was already checked for positivity, this check
can be removed entirely. It was not a miswritten check that intended to check
i instead of reg, because i is already checked.

This libcrypto dependency sucks. Linking against OpenSSL is sort of broken in
certain Mac OS X SDKs. libcrypto was only being used to provide an MD5
implementation. Breakpad already has its own MD5 implementation, so just use
that instead.
To be perfectly honest, on modern systems, nothing should be making MD5
hashes of modules anyway, because everything has an embedded LC_UUID.
The project file changes just remove libcrypto and add md5.c as needed.
A bonus (and untested) fix for on_demand_symbol_supplier.mm is included to
account for changes in r794.

In r779, at the last moment, I added a default call count expectation for
the UnnamedFunction warning to the CUFixtureBase constructor, but didn't
re-run the tests. This patch adjusts all affected tests.

This patch makes sure dump_syms behaves properly when presented with
malformed DWARF data that provides no name for a function. We print a
warning message to stderr, and subsitute "<name omitted>" for the empty
string, so that the "FUNC" record written to the symbol file for the
function is still well-formed. (We may have line number data covering the
function, so it would be a shame to omit the function altogether.)
Unit tests included.

Exported symbols on Mach-O binaries are defined in a STABS section. This patch makes stabs_reader handle them, adds support for Extern symbols in the Module class (which are output as PUBLIC lines in symbol files), and the proper processing in stabs_to_module to hook it all up.
