Implement face stipples on Android

* .gitignore:

* java/Makefile.in: Fix typos.

* java/org/gnu/emacs/EmacsFillRectangle.java (perform): Call
blitOpaqueStipple if filling an unobscured rectangle with an
opaque stipple.

* java/org/gnu/emacs/EmacsGC.java (EmacsGC) <tileObject>: New
field.
(markDirty): Synchronize the current stipple with tileObject.
(prepareStipple, blitOpaqueStipple): New functions.

* java/org/gnu/emacs/EmacsService.java (EmacsService)
<resources>: New static field.
(onCreate): Set it.

* src/android.c (android_create_bitmap_from_data): Correct order
of arguments to android_create_pixmap_from_bitmap_data.
(HAS_BUILTIN_TRAP): Delete macro.
(emacs_abort): Always induce backtraces by means of a NULL
pointer deference.

* src/dispextern.h (Emacs_GC, Emacs_Rectangle, GCForeground)
(GCBackground, GCFillStyle, GCStipple, FillOpaqueStipple)
[HAVE_ANDROID]: Define to their Android counterparts rather
than simulating their existence.

* src/epaths.in: Set bitmap path to /assets/bitmaps on Android.

* src/image.c (image_bitmap_pixmap): Also enable when
HAVE_ANDROID.

* src/sfntfont-android.c (sfntfont_android_put_glyphs): Assert
that this is never called to draw a stippled background.
* src/xfaces.c (x_create_gc) [HAVE_ANDROID]: Redefine as
wrapper around android_create_gc.
(prepare_face_for_display) [HAVE_ANDROID]: Enable stipples.
