d606de6bb6 Refactor some code in surfaceflinger in preparation of upcoming changes
the new TextureMagager class now handle texture creation and upload
as well as EGL image creation and binding to GraphicBuffers. This is
used indirectly by Layer and directly by LayerBuffer

the new BufferManager class handles the set of buffers used for a
Layer (Surface), it abstracts how many buffer there is as well as
the use of EGLimage vs. regular texture ops (glTexImage2D).

c0a9164e9e Add support for enqueuing buffers in arbitrary order
Also added a very simple SharedBufferStack unit test.

b296533607 cleanup. waitForCondition() now uses polymorphsim instead of templtes
the reason for the above change is that waitForCondition() had become
large over time, mainly to handle error cases, using inlines to
evaluate the condition doesn't buys us much anymore while it increases
code size.

0a8cd0689a fix a race condition in undoDequeue(), where 'tail' could be computed incorrectly.
in the undoDequeue() case, 'tail' was recalculated from 'available' and 'head'
however there was a race between this and retireAndLock(), which could cause
'tail' to be recalculated wrongly.

the interesting thing though is that retireAndLock() shouldn't have any impact
on the value of 'tail', which is client-side only attribute.
we fix the race by saving the value of 'tail' before dequeue() and restore it
in the case of undoDequeue(), since we know it doesn't depend on retireAndLock().

cc08e688f5 added setCrop() to android_native_window_t
hooked up the new method up to Surface.cpp
the actual crop is not implemented in SF yet

1100c8b901 add support for up to 16 buffers per surface
also increase the dirtyregion size from 1 to 6 rectangles.
Overall we now need 27KiB process instead of 4KiB

3a80695667 fix [2420565] Surface.lockCanvas() updates the dirty region too often
There was a bug where we were we could be reallocating buffers for no reason.

26d244281a libutils Condition are now PRIVATE by default
Condition must be initialized with SHARED for the old behavior, where
they can be used accross processes.

Updated the two places android that require SHARED conditions.

PRIVATE conditions (and mutexes) use more efficient syscalls.

55fa25161a implement connect/disconnect in our native_window_t implementations
the framebuffer implementation doesn't do anything special with this
but the surfaceflinger implementation makes sure the surface is not used
by two APIs simultaneously.

c2e30de00c Fix a small bug where we could compute SharedBufferStack's tail incorrectly.
Also add "tail" to the debug dump().

285dbde2e0 Added a name to Surface created by SurfaceFlinger
Updated the window manager to use this new facility.
Surfaces name are now printed by "dumpsys".

98e71ddaed remove a dependency of GraphicBuffer (libui) on Parcel (libbinder).
Add a Flattenable interface to libutils which can be used to flatten
an object into bytestream + filedescriptor stream.
Parcel is modified to handle Flattenable. And GraphicBuffer implements
Flattenable.

Except for the overlay classes libui is now independent of libbinder.
