Simplify management of Android handle IDs

* java/org/gnu/emacs/EmacsCursor.java (EmacsCursor):

* java/org/gnu/emacs/EmacsGC.java (EmacsGC):

* java/org/gnu/emacs/EmacsHandleObject.java (EmacsHandleObject):
Remove HANDLE argument to constructor.

* java/org/gnu/emacs/EmacsPixmap.java (EmacsPixmap):

* java/org/gnu/emacs/EmacsWindow.java (EmacsWindow):

* java/org/gnu/emacs/EmacsInputConnection.java
(EmacsInputConnection) <windowHandle>: Change type to long.

(setComposingText, setComposingRegion, setSelection)
(performEditorAction, performContextMenuAction, getExtractedText)
(requestSelectionUpdate, requestCursorUpdates, clearInputFlags)
(getSurroundingText, takeSnapshot, getSelection): Accept handles
as longs, rather than shorts.  All callers changed.

* java/org/gnu/emacs/EmacsService.java (queryTree): Return
handles as longs rather than shorts.
(viewGetSelection): Take long WINDOW, not short.

* src/android.c (struct android_emacs_handle): New structure.
(handle_class): New variable.
(android_init_emacs_service, android_init_emacs_pixmap)
(android_init_emacs_gc_class, android_init_emacs_cursor): Adjust
to match signature changes in constructors.
(android_init_emacs_handle): New function.
(initEmacs): Initialize the handle class, its fields and metods.
(sendConfigureNotify, sendKeyPress, sendKeyRelease, sendFocusIn)

(sendButtonRelease, sendTouchDown, sendTouchUp, sendTouchMove)
(sendWheel, sendIconified, sendDeiconified, sendContextMenu)
(sendExpose, sendDndDrag, sendDndUri, sendDndText): Update for
changes to handle type.
(android_alloc_id, android_resolve_handle)
(android_resolve_handle2): Remove functions; replace the second
with a macro that accepts one fewer argument.  All callers
changed.
(android_destroy_handle): Cease indexing the handle list for the
handle object.
(android_globalize_reference): New function.
(android_create_window, android_create_gc, android_create_pixmap)
(android_create_font_cursor): Call android_globalize_reference
to convert global references into handles.
(android_free_cursor, android_destroy_window): Cease verifying
the handle type.
(android_copy_area): Check destination object type rather than
handle entry.
(android_query_tree): Adjust for changes to return types.
(likely): Define __builtin_expect variant unconditionally.

* src/android.h (android_resolve_handle): New macro.

* src/androidgui.h (android_handle): Define to intptr_t.

* src/androidterm.c (deleteSurroundingText, finishComposingText)
(performEditorAction, performContextMenuAction, getExtractedText)
(getSelectedText, requestSelectionUpdate, requestCursorUpdates)
(clearInputFlags, getSurroundingText)
(android_get_surrounding_text_internal): Accept handles as
longs, not jshorts.
