When there are upwards of 200 threads in a crashing process, each having an
8KB stack, this can result in a huge, 1.8MB minidump file. So I added a
parameter that, if set, can compel the minidump writer to dump less stack.
More specifically, if the writer expects to go over the limit (due to the
number of threads), then it will dump less of a thread's stack after the
first 20 threads.
There are two ways to specify the limit, depending on how you write minidumps:
1) If you call WriteMinidump() directly, there's now a version of the
function that takes the minidump size limit as an argument.
2) If you use the ExceptionHandler class, the MinidumpDescriptor object you
pass to it now has a set_size_limit() method you would call before
passing it to the constructor.

Breakpad can be used on processes where a mistaken
library saves then restores one of our signal handlers
with 'signal' instead of 'sigaction'.
This loses the SA_SIGINFO flag associated with the
Breakpad handler, and in some cases (e.g. Android/ARM
kernels), the values of the 'info' and 'uc' parameters
that ExceptionHandler::SignalHandler() receives will
be completely bogus, leading to a crash when the function
is executed (and of course, no minidump generation).
To work-around this, have SignalHandler() check the state
of the flag. If it is incorrectly unset, re-register with
'sigaction' and the correct flag, then return. The signal
will be re-thrown, and this time the function will be
called with the correct values.

- One of the unit test binaries refused to link due to
missing linker flags.
- The WriteDSODebug() function now works on Android, so
do not special-case it anymore.
- Ensure android/run-checks.sh will complain properly if
the client unit test suite fails on Android. It used to
consider that such failures were acceptable. Note that
it still considers failures when running the tools and
processor test suite on the device normal (fixing this
is a lot harder, and these parts of Breakpad typically
never run on a device, but on the host).

Currently, if a thread's stack pointer is not within a valid memory page,
the minidump writing will fail with an error. This change allows an invalid
stack pointer by simply setting the memory size to zero in the minidump.
The processing code already checks for the size being zero, although it
currently just gives an error (see https://breakpad.appspot.com/413002/).

If none of the installed ExceptionHandlers handle a signal (their
FilterCallbacks or HandlerCallbacks all return false), then the signal
should be delivered to the signal handlers that were previously
installed.
This requires that old_handlers_ become a static vector so that we can
restore the handlers in the static HandleSignal.
Currently it is also restoring signals in ~ExceptionHandler (if there
are no others). This should not be required since our documentation
states that a process can only have one ExceptionHandler for which
install_handlers is true (and so we get the correct behavior if we
simply leave our handlers installed forever), but even the tests
themselves violate that.

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

In order to better distinguish Android and Linux minidumps, introduce
a new MD_OS_ANDROID definition, and modify related source code accordingly.
Also append the build-fingerprint to the minidump location descriptor.
This gives more information about the system image the device runs on.
