Fixes#2122Fixes#1454
Addendum (est31)
According from its docs in android_native_app_glue.h (from the NDK), the
onInputEvent should "Return 1 if you have handled the event, 0 for any
default dispatching". Before, we always returned 1, meaning we blocked
all hardware keys to be given to the OS.
This broke the volume keys and has caused #2122 and #1454.
Although it bases on lots of guesswork, it can probably safely be said that
CGUIEnvironment::postEventFromUser returns true if the event was handled,
and false if not. Therefore, set the status variable depending on what
postEventFromUser returned.
The old Ant build system has been deprecated for a while and new development is focused on Gradle.
I also removed a hardcoded string that lint caught and moved the patch files to a subdirectory.
I left the JNI files in the root directory.
