ANativeWindow::queueBuffer takes ownership of the fence fd passed to
it, and will close it before returning. SurfaceFlinger's screenshot
code was also closing the syncFd it passed to queueBuffer. Most of the
time this meant the second close() silently failed, but in a rare race
condition the file descriptor could be reused between the two
close()s.

On one device there is a bug, not yet root-caused, that causes fence
fds to not make it across binder from producer to consumer in the
IGraphicBufferProducer::queueBuffer call. Rather than returning an
error, which the producer typically treats as a fatal error, this
change allows the buffer to be queued with no fence. This avoids an
application crash at the risk of (likely single-frame) visible
corruption.

Copies the /data/misc/keychain/cacert-* directories to all users on
the device, whereas previously they were simply copied to user 0.
This is a shallow copy so anything that wasn't supposed to be there
will disappear.

Print more details about the exact reason that an ANR has occurred.
Also start checking that the window actually has a registered
input connection that is not in a broken state. These windows
are supposed to be cleaned up by the window manager promptly
as if the app had crashed but the pattern of ANRs we are observing
suggests that broken windows might be sticking around longer than
they should.

Previously it was possible to have the driver's eglTerminate called beofre
eglDestroyImageKHR in GLConsumer. This was because we didn't increment the
refcount for the lifetime of the image. This could lead to a crash or a deadlock
when multiple threads called terminate and destroy simultaneously.

Throttling was previously controlled by a combination of the
driver and the number of buffers in the queue. This patch makes
a more consistent trade-off, which allows two GPU frames pending
but not three. More buffering could improve throughput in the
case of varying frame times, but this also increases latency.
