Small cleanups:
Refactor the post-windowing setup into gl_init_driver() in video_gl.c
Move gl_sl.c into src/drivers and tidy up a bit.
Fix OS X compiling plugins with -mdynamic-no-pic

...

Fix have_shaders in glrender.c
Set negative fog for lut when using shaders
src/pvr2/glrender.c
src/pvr2/scene.c

Move glsl loading into common gl code, and set a display capability flag
src/display.h

Add support for armv7-a abi and make it the default - it's a good bit faster
Makefile.am
Makefile.in
configure
m4/android.m4
src/Makefile.in

Set min-sdk to gingerbread, but target honeycomb (for the action bar)
android/AndroidManifest.xml

Load previous GD-ROM on startup
src/gui_android.c

Include precision spec for GLES only
src/pvr2/shaders.glsl

Support depth component 16 as well as 24 (add capability flag for the available bits)
Put remaining TODOs inside HAVE_OPENGL_FIXEDFUNC blocks
Add swap-buffer calls for EGL (does not appear to support rendering directly
to front-buffer)

Add explicit precision (required by ES SL) and remove unnecessary
gl_FragDepth assignments
src/pvr2/shaders.glsl

Fully clean the android part before building it - dependencies don't seem to
work properly.
Add install-adb rule for convenience
