This change moves some common fence handling code into the base class for
BufferQueue consumer classes. It also makes the ConsumerBase class initialize
a buffer slot's fence with the acquire fence every time a buffer is acquired.

the problem was that LayerBase::setPerFrameData() was always setting
this flag. in fact there was no reason to do this at that point since
the layer is initialized to a default state in setGeometry().

If SurfaceFlinger needs to refresh the screen but the dirty region is
empty, it won't set the layer acquire fences, and stale file
descriptors will be passed to HWC commit(). Now we make sure to clear
the stale file descriptors for each layer right after commit().

- the library is dlopened from libsurfaceflinger
- the library built only when libnativehelper exists

we used to have a visibleRegion object per layer, but now
it's per screen; so at somepoint the code got changed to
calculate the per-screen visible region on the stack and that's
what got passed to HWC.
we're now setting the visibleRegionScreen at each frame and
freeing at after the HWC set() call. We use the underlaying
SharedBuffer so that in most cases we don't have to allocate,
free or copy memory around.

This change makes BufferQueue derive the min undequeued buffer count from a max
acquired buffer count that is set by the consumer. This value may be set at
any time that a producer is not connected to the BufferQueue rather than at
BufferQueue construction time.

this would happen when the composition was handled
entirely in h/w composer, in this case, we would
not set the fences for any involved layers.

This change is a clean up of some of the handling of the maximum number of
buffers that are allowed at once. It mostly renames a few member variables and
methods, but it includes a couple small refactorings.

this happened because we didn't check that the visible
region was within the bounds of the display.

DisplayDevices are now keyed of the wp<IBinder> the client uses.
DisplayID has now become DisplayType which is just used to identify
physical displays (as opposed to virtual displays such as wifi displays).

Use only display tokens in the API to refer to new displays.
Don't require the caller to specify the display when creating
a surface (since in general a surface could be shown on
any display).
This is intended to be a minimum change just to update the API.
Note that SurfaceFlinger still uses DisplayID in a few places
internally that might cause some features not to work properly
when there are multiple displays (LayerScreenshot, for example).

The primary display device was being configured to "blank" by
default, which prevented the boot animation from appearing
(unless you got lucky with the hardware composer state).

(This reverts an earlier revert.)
HWComposer can now create IDs representing a display
it can deal with. IDs MAIN and HDMI are reserved.
SurfaceFlinger associate HWComposer IDs with a
DisplayDevice and uses that when it talks to HWComposer.
A DisplayDevice doesn't have to have a HWComposer ID,
in that case it just can't use h/w composer composition.

- we now clean-up "dead" connection in the main loop,
this entirely avoid the problem with the side effects of
releasing strong references. We now only hold on to strong
reference for the connection we will signal.
- also simplify how we build the list of "ready" connections, by
only adding them to the list when we did receive a vsync event

- one issues caused most timestamps to be reported as 0
- on rare occasions an uninitialized variable could be used
- vsync counts per connection were accessed unthreadsafely
we now have 2 lists of connections in the main loop, one just
keeps a list of strong refs to the connections because once
we have a strong ref we're not allowed to release it while
holding the lock.
the 2nd list holds the connections that have a vsync event to
be reported. all the calculations are made with the lock held.
Change-Id: Iacfad3745b05df79d9ece3719bd4c34ddbfd5b83
problem was that we were acquiring a strong reference
on Connection object with a lock held, when those
got out of scope (lock still held) their dtor
could be called if all other refs had dropped,
the dtor would acquire the lock again to
remove the Connection from the main list. boom.
we rearange the code so this doesn't happen.

when multiple displays are connected, we ended-up having to
call eglMakeCurrent() twice per display due to a limitation
in EGL. this fixes that.

fix a few bugs with external displays
- HWComposer doesn't really handle multiple displays yet
so there is a lot of ugliness there
- We also need to make sure that external displays are not
blanked by default
- due to some EGL limitations surfaces being swapped need
to be current
