digit@chromium.org 7e3c538af1 Add custom getcontext() implementation for Android.
This adds a minimalistic implementation of getcontext()
for Android/ARM and Android/x86. The provided code is
in assembly and only implements the bare minimum required
by Breakpad to get the current processor state.

Note that:

- The FPU state is not saved to the ucontext_t on ARM.
  (that's actually the main difference with a normal
   getcontext() implementation).

  This is normal. On Linux/ARM, such state must be
  obtained with PTRACE_GETVFPREGS instead. This will
  be implemented in a future patch.

- On x86, only the 'regular' FPU state is saved, to
  mimic the GLibc/i386 implementation. The state of
  SSE/SSE2/etc registers is not part of the upstream
  getcontext() implementation.

# ndk-build module definition for the Google Breakpad client library
#
# To use this file, do the following:
#
# 1/ Include this file from your own Android.mk, either directly
# or with through the NDK's import-module function.
#
# 2/ Use the client static library in your project with:
#
# LOCAL_STATIC_LIBRARIES += breakpad_client
#
# 3/ In your source code, include "src/client/linux/exception_handler.h"
# and use the Linux instructions to use it.
#
# This module works with either the STLport or GNU libstdc++, but you need
# to select one in your Application.mk
#
# Sanity check. We can only build for ARM for now.
