Subject: [PATCH] ; Insert missing JNI prologues

* src/android.c (shouldForwardMultimediaButtons)
(shouldForwardCtrlSpace, notifyPixelsChanged, setupSystemThread):

* src/androidvfs.c (safSyncAndReadInput, safSync, safPostRequest)
(ftruncate): Insert absent JNI prologues.

(cherry picked from commit 8e0f134653b2951e80cd5659fba5c36e416931fa)
