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
1.11.1 or later. This will cause older versions of automake to refuse
to process the Makefile.am file.
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
(The change to Makefile.in is a consequence of my having neglected to
rebuild Makefile.in after landing r517.)

- Introduces a standard API for dealing with modules. MinidumpModule
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
SourceLineResolver. Reliance on the specific implementation in
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.
- The sample minidump_stackwalk tool prints the module list after printing
all threads' stacks.

- Test StackwalkerX86 and StackwalkerPPC on the current process, if built
by a supported compiler (gcc) on a supported (walkable) CPU (x86, ppc).
- This test is not enabled by default because of certain optimizations
that interfere with it (stack frame reuse, frame pointer omission). See
the comments at the top of stackwalker_selftest.cc. To enable this
test in the standard "make check" suite, configure with --enable-selftest.

- Place objects in the appropriate directories, instead of filling up
the root directory.
- Remove namespace macros, which made maintenance troublesome and which
created a dependency on config.h in public headers
- Skip useless Fortran checks at configure time
