Handle block helper functions in Breakpad symbol parser.  Block helper functions are associated with a source file but not associated with any line number.  For such functions, the Breakpad symbol file contains 0 for the line numbers.  Hence, 0 should be threated as valid line number.  For more information on block helper functions, please, take a look at http://clang.llvm.org/docs/Block-ABI-Apple.html.

Here is the symbol parser output:

Fix the Android/MIPS build.

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.

Support symbol dumping for ARMV8 iOS apps.

In my testing, ARM V8 object files and ARM V8 slices of universal binaries do
not contain debug_frame sections (at least at this time), and hence dump_syms
does not output CFI for ARM V8 even in the absence of the "-c" flag.

increase exception handler stack size for dumping thread

When running unittests under ASAN, we see that these code paths can
slightly smash the stack.  Double it to avoid that.
