This prevents strong reference cycles when the listener implementation also
holds a strong pointer to the ConsumerBase

This change fixes a number of small glitches that can occur when
multiple components in the same process are updating surfaces.
One would expect that updates to disjoint sets of surfaces would
not collide but this is not the case. The first component to
close the global transaction causes all pending updates to
be applied, including those that another component might not
have finished setting up if it also had an open transaction
at the same time.

This patch adds a hashtable-based LRU cache. This should be
significantly higher performance than the GenerationCache it is intended
to replace. It is a large part of the fix for bug 7271109
TextLayoutCache low-level performance issues.
We added a new method to BasicHashtable to detect when rehashing is
needed, because the internal linked list pointers would get invalidated
by that rehashing.
Also, the hash_type specialized to pointers had a small flaw.

This change adds support for displays that are not allowed to display surfaces
with the eSecure flag set. All non-virtual displays are considered secure,
while virtual displays have their secure-ness specified at creation time.

This change adds a transaction flag for WindowManager to indicate that a
transaction is being used to animate windows around the screen. SurfaceFlinger
will not allow more than one of these transactions to be outstanding at a time
to prevent the animation "frames" from being dropped.

This change makes BufferQueue::dequeueBuffer release its mutex before
allocating new buffers. This should alleviate lock contention in
SurfaceFlinger where SF's main thread can get blocked waiting for an allocation
operation to complete.

error codes are returned in errno, this caused ::waitForwever()
to only wait for 1 second and return improper error code (-1).

This needs the ConsumerBase mutex locked, but wasn't locking it. Two
of the four places that called it already held the lock so were fine.
Now addReleaseFence() takes the lock itself, and I added
addReleaseFenceLocked() for the two already-locked callers, since in
one of them dropping the lock would be inconvenient.

The CleanSpec is missing parens, which causes $P to be interpreted as a
single variable, and the following printed to the log:
Clean step: rm -rf RODUCT_OUT/obj/SHARED_LIBRARIES/libgui_intermediates
This patch adds parens as needed.

This change adds debug info to SurfaceFlinger's dumpsys to indicate that the
USE_WAIT_SYNC compile option was enabled, and it removes the
ALLOW_DEQUEUE_CURRENT_BUFFER option.

This allows us to blank and unblank displays other than the built-in

This adds a line to the "dumpsys SurfaceFlinger" output that shows
build-time configuration values.
Example:
Build configuration: [sf HAS_CONTEXT_PRIORITY] [libui] \
