Update Android port

Update Android port

* java/org/gnu/emacs/EmacsDrawLine.java: Fix this again.  Gosh,
how does Android do this.
* java/org/gnu/emacs/EmacsNoninteractive.java (main): Port to
Android 2.3.3.

* java/org/gnu/emacs/EmacsSdk11Clipboard.java
(EmacsSdk11Clipboard): Port to Android 4.0.3.
* java/org/gnu/emacs/EmacsService.java (getClipboardManager):
New function.

* src/alloc.c (find_string_data_in_pure): Fix Android alignment
issue.

* src/android-emacs.c (main): Port to Android 4.4.
* src/android.c (initEmacs): Align stack to 32 bytes, so it ends
up aligned to 16 even though gcc thinks the stack is already
aligned to 16 bytes.

* src/callproc.c (init_callproc): Use /system/bin/sh instead of
/bin/sh by default.
