A previously exited Thread object refuses to run again, if the
thread-id of the caller, conincides with the thread-id it previously
used in the worker thread. Hence reset the previously used worker
thread-id to -1 when it exits.

Generally we never want to lock a buffer for write access if it is at
the "head" on the surfaceflinger side. The only exception (1) is when
the buffer is not currently in use AND there is at least one queued
buffer -- in which case, SurfaceFlinger will never use said buffer
anymore, because on the next composition around, it will be able to
retire the first queued buffer.
The logic above relies on SurfaceFlinger always retiring
and locking a buffer before composition -- unfortunately this
didn't happen during a screenshot.
This could leave us in a situation where a buffer is locked by the
application for write, and used by SurfaceFlinger for texturing,
causing a hang.
Here, we fix this issue by never assuming the exception (1), it was
intended as an optimization allowing ANativeWindow::lockBuffer() to
return sooner and was justified when most of SF composition was
done in software. The actual buffer locking is now ensured by
gralloc. We could have handled screenshots in a similar way to
a regular composition, but it could have caused glitches on screen,
essentially, taking a screenshot could cause to skip a frame.
now that we removed the notion of a "inUse" buffer in surfaceflinger
a lot of code can be simplified / removed.
noteworthy, the whole concept of "unlockClient" wrt. "compositionComplete"
is also gone.
We used to guarantee that a layer in SurfaceFlinger would never be
destroyed before all references (to its ISurface) on the client
side would be released. At some point, this guarantee got
relaxed to allow to free gralloc resources sooner. This last
change was incorrect, because:
- in implementations with reference-counting the gralloc resources
wouldn't be released anyways, until all the mapping were gone
- in implementations without ref counting, the client side
would most likely crash or do something bad
- it also caused the SharedBufferStack slot to be reallocated
to another surface, which could be problematic if the client
continued to use the surface after the window manager destroyed it.
So, we essentially reinstate the guarantee that layers won't be
destroyed until after all references to their ISurface are
released.
NOTE: This doesn't entirely fix 3306150 because there is another
problem there where the Browser continues to use a surface after it
has been destroyed.
also improve SurfaceFlinger 'dumpsys' log
list the purgatory, which shows windows that have been closed,
but for which the client still has references.
InputReader::getSwitchState always returns AKEY_STATE_UNKNOWN
because SwitchInputMapper::getSources() returns 0 which cannot
match any source mask including AINPUT_SOURCE_ANY. As a result
initial lid switch detection is broken.
This change adds a new source constant AINPUT_SOURCE_SWITCH
that indicates that the source has switches.

Two of the cases in the ISurfaceComposer onTransact switch statement
were missing 'break' statements at the end, and would fall through to

Adds a new virtualKeyQuietTimeMillis configuration resource that sets
the duration for which virtual keys will be dropped after recent touches
on screen. The default value is 0; it is intended to be overridden
per device using a resource overlay.
This change is designed to help in two cases:
1. Swipes from touchscreen into virtual key area.
2. Accidental taps in virtual key area while using on-screen keyboard.

The cause of the problem is that AudioTrack::start() can fail if it is called from a newly created
thread that has the same ID as the AudioTrack callback thread that has just been stopped and not yet exited.
This is possible as the thread ID used by the Thread class is not the TID.
The fix consists in clearing the thread ID before exiting the thread loop.

Rewrote interceptKeyBeforeQueueing to make the handling more systematic.
Behavior should be identical except:
- We never pass keys to applications when the screen is off and the keyguard
is not showing (the proximity sensor turned off the screen).
Previously we passed all non-wake keys through in this case which
caused a bug on Crespo where the screen would come back on if a soft key
was held at the time of power off because the resulting key up event
would sneak in just before the keyguard was shown. It would then be
passed through to the dispatcher which would poke user activity and
wake up the screen.
- We propagate the key flags when broadcasting media keys which
ensures that recipients can tell when the key is canceled.
- We ignore endcall or power if canceled (shouldn't happen anyways).
Changed the input dispatcher to not poke user activity for canceled
events since they are synthetic and should not wake the device.
Changed the lock screen so that it does not poke the wake lock when the
grab handle is released. This fixes a bug where the screen would come
back on immediately if the power went off while the user was holding
one of the grab handles because the sliding tab would receive an up
event after screen turned off and release the grab handles.

If writeString8 is called with the following sequence:
writeString8(String8(""));
writeString8(String8("TempString"));
Then in the readString8, the 2nd String i.e. "TempString" is not read,
instead an empty string is read.
The bug comes because of the write call for String8("") where there are
no String bytes present. In the write Statement, an extra ‘\0’ is
written. During the Marshalling, Following bytes are written:
1 2 3 4 5 ...
0x0 0x0 0xB ‘T’ ‘e’ ...
The readString8 function has a check that, if String length is 0, don’t
read anything. So the first byte is read as the length for the first
string. The second byte i.e. ‘\0’ is read as the length for the second
string and hence the second string becomes empty too.

[3171580] SurfaceFlinger Bypass mode. (DO NOT MERGE)
[3171580] Add transform field to native buffers. (DO NOT MERGE)
some of these failures are not fatal and even expected in some cases
so they should not emit a dump in the log in those cases.

This change fixes a bug in the dispatcher where the window manager
policy would incorrectly receive a key repeat count of 0 in the case
where the key repeat was generated by the hardware or driver.
Long-press on HOME was broken as a result.
Repeating keys could also get stuck down.

This change defines a macro NUM_FRAME_BUFFERS to set
the desired number of framebuffers to be used by the UI,
instead of hard-coding 2 framebuffers.
Aditional logic has been added to handle the initialization
and destruction of NUM_FRAME_BUFFERS buffers.

Two issues:
1. First, due to an inverted conditional in the input dispatcher, we were
reporting touches as long touches and vice-versa to the power manager.
2. Power manager user activity cheek event suppression also suppresses touch
events (but not long touch or up events). As a result, if cheek event
suppression was enabled, touches would not poke the user activity timer.
However due to the above logic inversion, this actually affected long
touches. Net result, if cheek suppression was enabled in the power manager
and you held your thumb on the screen long enough, the phone would
go to sleep!
Cheek event suppression is commonly turned on when making a phone call.
Interestingly, it does not seem to get turned off afterward...
This change fixes the logic inversion and exempts touches from the cheek
suppression. The reason we do the latter is because the old behavior
was actually harmful in other ways too: a touch down would be suppressed
but not a long touch or the touch up. This would cause bizarre behavior
if you touched the screen while it was dimmed. Instead of brightening
immediately, it would brighten either when you lifted your finger or
300ms later, whichever came first.
