Original commit message:
[Android]: Remove __system_property_get(ro.build.fingerprint) from
WriteOSInformation.
__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.

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 '('.

The ElfCoreDumpTest.ValidCoreFile unit test assumed that the number of
NT_FPREGSET / NT_PRXFPREG notes in the core dump file equals to the number of
threads of the crashed process. This assumption isn't always true as the kernel
skips filling the NT_FPREGSET / NT_PRXFPREG note of a thread if the FPU state
isn't available. The kernel indicates the availability of NT_FPREGSET /
NT_PRXFPREG via the pr_fpvalid field of the NT_PRSTATUS note. This CL modifies
the ElfCoreDumpTest.ValidCoreFile unit test to verify the number of NT_FPREGSET
and NT_PRXFPREG notes based on the pr_fpvalid field of the NT_PRSTATUS notes.

This is an initial attempt to add Arm64 (aarch64) support to Breakpad for
Linux / Android platforms. This CL adds the Arm64 data structures, but does
not yet implement the Android getcontext support or CPUFillFromThreadInfo /
CPUFillFromUContext.

The current CreateChildCrash logic is racy when it comes to creating a
crash dump for two reasons:
The main thread that calls kill() on a different thread is guaranteed
the signal will be *queued* when it returns, but not *delivered*. If
the kernel doesn't automatically schedule the receiving thread, but
instead lets the main thread run to the exit() call, then the signal
never triggers a coredump and the whole process simply exits.
The main thread is using kill() to try to deliver a signal to a
specific thread, but that function is for sending signals to a
process. That means the kernel is free to deliver the signal to
any thread in the process and not just the one requested. This
manifests itself as the pr_pid in the coredump not being the one
expected. Instead, we must use tkill() with the tid (which we
already took care of gathering) to deliver to a specific thread.
These are a lot easier to see on a UMP system as contention is heavier.
