getcontext is also not available on musl libc, so generalize
breakpad_getcontext so it can be used as a fallback for non-Android
platforms as well.
On x86_64 and i386, ucontext_t uses an Android-specific offset for
storage of FP registers, since its sigset_t differs in size. So,
make the definition of MCONTEXT_FPREGS_MEM and UCONTEXT_FPREGS_MEM_OFFSET
conditional on whether we are building for Android.
On glibc and musl, signal.h and asm/sigcontext.h can't be included
together, so in breakpad_context_unittest.cc, only compare the libc
and kernel _fpstate when on Android.

mixing the address of an object to the current time when generating the

$ 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.

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.

This patch remove many Android-specific #ifdefs from the Breakpad
source code. This is achieved by providing "fixed-up" platform
headers (e.g. <signal.h> or <sys/user,h>), in the new directory
src/common/android/include/, which masks differences between
the NDK and GLibc headers.
The old "android_link.h" and "android_ucontext.h" are moved
and renamed.
This also requires putting this directory as the first
include path during Android-hosted builds, hence the
modification of Makefile.am and configure.ac

Change configure.ac to note that Breakpad requires automake version

Earlier versions of automake generate 'make dist' rules that have a
security flaw; see:
http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2009-4029
However, note that that notice itself has a flaw: the bug is *fixed
in* automake 1.11.1, not present. See:
http://lists.gnu.org/archive/html/automake/2009-12/msg00012.html

is now a concrete implementation of this API. Code may interact with
single modules using the CodeModule interface, and collections of
modules using its container, the CodeModules interface.
- CodeModule is used directly by SymbolSupplier implementations and

MinidumpModule has been eliminated.
- Module lists are now added to ProcessState objects. Module references
in each stack frame are now pointers to objects in these module lists.
