The Mac crash key manipulation code was intended to be thread-safe through the
provision of a mutex. The mutex operations were done inside an assert().
assert() is a no-op in NDEBUG (release) builds. Therefore, in release builds,
these operations were occurring without being protected by any mutex at all,
and were nowhere near thread-safe.

This is Chromium's base/memory/scoped_ptr.h at r98718, which split off
from the google3 version at a later point than Breakpad's copy. It is a
drop in replacement and the only changes are:
- removal of WARN_UNUSED_RESULT.
- moving it into the google_breakpad namespace.

- 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.

The inconsistent and duplicated references to gDebugLog caused
problems building on iOS and the current logging implementation
had little utility because it was never activated in debug builds.

There are a bunch of tests that use invalid memory acesses (on purpose)
to trigger a crash so that we can detect things are dumped correctly.
When we run under ASAN, it catches those accesses and the breaks the
testing flow.
For now, use the existing ADDRESS_SANITIZER symbol to disable more tests.
Ideally we'd use a compile-time attribute to disable ASAN on a few funcs,
but that seems to be broken atm.

If you try to process a file using a 32bit build that is larger than
2GiB in size, the linux kernel will reject things:
$ strace -eopen dump_syms ./chrome ./ > chrome.sym
...
open(".//chrome.debug", O_RDONLY) = -1 EOVERFLOW (Value too large for defined data type)
So let's use the existing autoconf macro to check for and enable support
as need be.
We have to shift the existing m32 logic up to before we start doing
feature test macros though otherwise a simple configure won't work:
$ ./configure --enable-m32
This is because it first tests LFS and such w/out the -m32 flags.

For CPUs that don't support the MMX instruction set, such pre-Pentium III or industrial x86 embedded PCs, the minidump fails when it tries to retrieve MMX specific registers.
This patch adds MMX detection for that call.

It is incorrect to wrap close in HANDLE_EINTR on Linux.
Unnecessary #includes of eintr_wrapper.h are also removed. The variable naming
within the macro is also updated per Chromium r178174.
einter_wrapper.h contains a non-mechanical change. Mechanical changes were
generated by running:

The std::string dumpFilename already contains the full pathname to the dump file. Appending it to the dumpDirAsNSString creates a string with the path portion duplicated, e.g.:

SIGABRT can be generated internally, usually by calling abort(),
or externally by another process. When the signal is generated
by the kernel, info->si_pid is 0 and the signal is treated in the
same way as an exception (SIGSEGV, etc.), but the assumption
that the exception happens again upon return from the handler
is wrong, so we must have a special case for this.

.raSearchStart in the cases where there are alignment operators in
the program string.
If alignment operators are found in the program string, the current
value of %ebp must be valid and it is the only reliable data point
that can be used for getting to the previous frame. Previously, the
.raSearchStart calculation was based on %esp and when %esp is aligned
in the current frame (which is a lossy operation) the resulting
.raSearchStart cannot was incorrect. There is code that is trying to
work around this problem (scanning of up to 3 words for a return
address) which is unreliable and it doesn't work in many cases (e.g.
when the alignment is on a 64-byte boundary).
This fix is already deployed in Google and it was measured to reduce
the number of wrong stack traces (for Windows crashes) by 45%. No
regressions have been found so far.
Here is an example of an issue that was fixed by this change (where
register %esp is aligned on the 64-byte boundary and the workarounds
that we already had didn't work):

Apparently, as of the 10.8 SDK, Apple has quietly decided that the first
argument to NSLocalizedString is supposed to be usable as-is as a format
string, instead of simply being the key to obtain a usable format string.
The recent clang trunk enforces this, resulting in build breaks like
crash_report_sender.m:560:14: error: data argument not used by format string [-Werror,-Wformat-extra-args]
displayName];
^
Breaking the result of NSLocalizedString into a temporary NSString* is enough
to suppress the warning.
