A Google modification to eglCreateWindowSurface was
causing SurfaceFlinger to set its swap interval
value back to 1, regardless of the value set in the
debug.gr.swapinterval property.
This patch modifies the fb_setSwapInterval function
in gralloc to check the debug.gr.swapinterval
property and not change the swap interval if a value
is set there.

Synchronize turning off of composition bypass with display,
so that close happens only after FB content is displayed.
This fixes blinks observed when bypass needs to be turned off,
for reasons other than video content.
