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.

Blobcache is not yet enabled for surfaceflinger (as it should be).
As a temporary workaround, generate all needed shaders during
surfaceflinger initialization instead of doing the compilation
on-demand during ui transitions.

i) Call removeFd() only if the fd in the BitTube has been
previously added to the Looper. Use a flag to determine whether the fd
has been previously added or not.
ii) Increment mPendingFlushEventsToSend after holding a connectionLock.
iii) Store the number of acks that are pending in SensorEventQueue
and send them all at once.

Sometimes dumping threads takes a long time and bugreport times
out. This change will cause us to accept the bugreport socket connection
before dumping threads and should avoid the failed to connect to dumpstate
service problems we've seen.

We normally recompute layer visibility when a layer gets its first
buffer; before then it's treated as invisible. Sideband layers never
get a buffer (as far as SurfaceFlinger knows), so never became
visible. Now we also recompute visibility when a layer gets a new
sideband stream.

Try to clean up the code paths coming in and out of binder IPCs to
plug any places where we could disrupt the gather flag of a thread,
causing it to keep gathering stack crawls (which is the thing that
is causing our strict mode data to become so large).
We now take care of saving and restoring this state in the core
IPC code path, not at the Java layer.

When HWC doesn't provide DPI values for a display, we pick a default
DPI based on resolution. The intent was that 1080p and higher displays
would get XHIGH density, and lower resolutions would get TV density.
In KK (and possibly forever) we had a bug that we'd always use TV
density. That was fixed in L, but that fix exposed a pre-existing bug
that we always used the display's height in its native orientation,
rather than in landscape orientation. So an 800x1280 tablet like N7v1
started getting XHIGH density instead of the intended TV density.

If the destructor of SensorEventConnection gets called when the main
sendEvents loop of SensorService is executing it may result in a deadlock.
The loop promotes each connection to a strong_pointer, calls sendEvents
and cleans up the connection if necessary. It is possible that the sp's
destructor may delete SensorEventConnection which will call the dtor
~SensorEventConnection(). This dtor again needs SensorService mLock to
execute which may result in a deadlock.
