make with-android-headers optional

If --with-android-headers is not specified, try to use pkg-config.

Also, extract Android versions from android-version.h using
ANDROID_HEADERS_CFLAGS and the preprocessor.

extract bionic kernel headers

This patch correctly extracts bionic kernel headers instead
of those under external/kernel-headers/original/.

From external/kernel-headers/original/README.txt:
  This directory contains the original kernel headers that are used to generate Bionic's "cleaned-up" user-land headers.
  They are mostly covered by the GPLv2 + exception, and thus cannot be distributed as part of the platform itself.
  (NOTE: The cleaned up headers do not contain copyrightable information and are distributed with Bionic)

dynamically add hooks from glibc

The hook table contains
a. functions that need parameter conversion
   (like parameters of type FILE*, or pthread_mutex_t*)
b. some of the pthread_ functions we know to work from glibc.
   The pthread functions that we don't have in the hook table,
   when called by client code, will cause a crash.

If a symbol is not found in the hook table, it's searched
in libc.so.6. If it's not found there, then we fallback to bionic.

So far, this patch covers bionic{libc,libdl} and a part of libthread_db.
Still to be covered is libm, libstdc++ and linker.

For debugging purposes, one can use HYBRIS_FROM_BIONIC to
force a symbol to be used from Bionic.

So far, I only need longjmp and setjmp from bionic{libc}, everything else
being called from (e)glibc.

Tested on nexus 4 as:
  HYBRIS_EGLPLATFORM=hwcomposer \
  ./ARMHF/bin/test_hwcomposer

egl: Add a module_init function for loading modules and pass EGL functions into the platform modules
egl:wayland: Send a wl_display.sync event after wl_surface.commit in queueBuffer

Some compositors, namely weston, queue buffer release events and wait until
something like a frame event to flush them out.  Without a frame event, you
need to send a wl_display.sync event to ensure that the resulting
wl_buffer.release actually gets sent.  Without this, you may get starved
for buffers.
egl:wayland: Properly handle eglSwapBuffer commit symantics

eglSwapBuffers should not return without calling wl_surface.commit.  This
is because wl_surface.commit is used to synchronize a lot more than just
the currently attached buffer and damage.  Unfortunately, in some EGL
implementations, eglSwapBuffers returns before queueBuffer is actually
called.  In particular, the Android binary blob for the Mali 400 does this.
To make matters worse, the Mali 400 blob doesn't call queueBuffers at all
if no rendering commands have been issued since the last swap.

In order to deal with this we notify the WaylandNativeWindow of the
impending swap, then call eglSwapBuffers on the parent implementation, and
then notify the WaylandNativeWindow once the swap is complete.  The
EGL_EXT_fence_sync extension is used ensure that the swap has actually
completed before we notify the window.  If the window has not seen a call
to queueBuffer yet, it simply does an extra commit.

The one other possible edge case here is if EGL_EXT_fence_sync is not
provided by the parent blob or if it doesn't work to detect the end of the
swap.  However, all that happens in this case is that we generate an extra
swap.  This means the protocol stream will be wrong, but not nearly as
wrong as it used to be.
