PageAllocator maps memory via sys_mmap(), implemented in
linux_syscall_support.h. We need to explicitly inform MSan that this memory is
initialized.

This patch makes two changes to breakpad to enable crash reporting to work correctly when the library is inside another file (an archive):
- Do not filter mappings which map an executable at a non-zero offset.
- If such an executable is mapped look in the ELF information for the
shared object name and use that name in the minidump.
Note this change doesn't care about the archive format and isn't Android
specific (though loading the shared library this way is currently only done on Android).

__system_property_get has been removed from the Android NDK for 'L' so Breakpad
no longer links. This CL just removes the call in WriteOSInformation because
Chrome already passes the build fingerprint as a crash key called "android_build_fp" in the crash report HTTP POST message.

After handling an uncaught NSException, release the Breakpad object
so there will not be a second crash dump logged.
Prior to this change, for every uncaught NSException handled through
the Breakpad::UncaughtExceptionHandler(), a second crash without
any useful information (generally __cxa_rethrow and std::__terminate)
is recorded.

This bug manifests itself on Android x64 (in ExceptionHandlerTest::ExternalDumper), but is possible on any platform.
The compiler is unaware of the code which runs in the signal handler which reads this variable. Without volatile the compiler is free to optimise away writes to this variable which it believes are never read.

- Convert time_t values to UTC correctly. It is incorrect to cast a uint32_t*
to time_t* because the two types may have different widths. This is the
case on many 64-bit systems, where time_t is a 64-bit signed integer.
Conversion is unified in a single function, and additional uses of time_t
in minidump files not previously displayed in UTC are now displayed.
- Interpret the IMAGE_DEBUG_MISC structure correctly.
- When printing MINIDUMP_SYSTEM_INFO structures, always show the "x86" side
of the union, and state whether it's expected to be valid. (Existing
Breakpad-produced non-Windows minidumps for x86_64 use the "x86" side of
union, but Windows minidumps for x86_64 use the "other" side, so I want to
print both.)

This CL introduces "--sobasedir" command-line option to minidump-2-core.
By default, paths to shared lib files included in generated core file are
formatted as "/var/lib/breakpad/[GUID]libFoobar.so". By using "--sobasedir",
this will be "[user-supplied-path]libFoobar.so".
This option can be used to ease debugging minidump files from developer's local
builds. By specifying "minidump-2-core --sobasedir `pwd`/out/Debug/lib/
foobar.mdmp", user can load the generated core file in gdb without setting up
the symlinks for "/var/lib/breakpad".

This has a substantial performance improvement over using the getSymbolsByAddr iterator, especially on certain 64bit DLLS. e.g. Time to process chrome_child.dll drops from 51 minutes to 21 secs.
Note: new test data looks different because the ordering of lines is no longer by memory address. This does not affect processing. The test data has been manually compared to old data and matches (except additional PUBLIC symbols). Also, INFO lines are omitted because the source executable files are not checked in, so they are unavailable.

After r1299, the LinuxCoreDumperTest::VerifyDumpWithMultipleThreads and
ElfCoreDumpTest::ValidCoreFile would both hang on Android. This appears to be due to the tkill
signal not being recieved by the thread which is meant to crash, even though tkill returns 0.
This CL retries sending the tkill signal multiple times, which prevents the Hang.

As part of that:
- Updated MSSymbolServerConverter to also download the executable files from the symbol server and pass them to the PDBSourceLineWriter as it is required for successful conversion of symbols for 64-bit modules.
- Added a .gyp file and target for the ms_symbol_server_converter library.
- Updated PDBSourceLineWriter to allow executable files to be in locations different from the locations of the PDB files.
- Minor style issue:
* #define guards.
* No space before ')' and after '('.
