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.

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.

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.

The cause of the problem is that AudioTrack::start() can fail if it is called from a newly created

This is possible as the thread ID used by the Thread class is not the TID.

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.

This change enables the framework to synthesize key events to implement
default behavior when an application does not handle a key.
For example, this change enables numeric keypad keys to perform
their associated special function when numlock is off.

so it can choose to ignore it.

The ShortcutManager used to only receive the key code of the key event
that triggered the shortcut. This change now provides the shortcut
manager with the whole key event so it can look up the associated
character using the correct key character map.
To make this more efficient, added a mechanism for recycling
key events. At the moment it is only used by key events owned by the
system process, since clients of the existing API (such as Views)
might continue to hold on to key events after dispatch has finished so
they would break if the key event were recycled by the framework.
Deprecated KeyCharacterMap.BUILT_IN_KEYBOARD.

Fixed a bug with dpad keys on external keyboards being rotated
according to the display orientation by adding a new input device
configuration property called "keyboard.orientationAware".
Added a mechanism for overriding the key layout and key character
map in the input device configuration file using the new
"keyboard.layout" and "keyboard.characterMap" properties.
Also added "trackball.orientationAware", "touch.orientationAware" and
"touch.deviceType" configuration properties.
Rewrote the configuration property reading code in native code
so that it can be used by EventHub and other components.
Added basic support for installable idc, kl, and kcm files
in /data/system/devices. However, there is no provision for
copying files there yet.
Disabled long-press character pickers on full keyboards so that
key repeating works as expected.

BREAKING CHANGE: Redesigned the key character map format to
accomodate full keyboards with more comprehensive suite of modifiers.
Old key character maps will not work anymore and must be updated.
The new format is plain text only and it not compiled to a binary
file (so the "kcm" tool will be removed in a subsequent check-in).
Added FULL keyboard type to support full PC-style keyboards.
Added SPECIAL_FUNCTION keyboard type to support special function
keypads that do not have any printable keys suitable for typing
and only have keys like HOME and POWER
Added a special VIRTUAL_KEYBOARD device id convention that maps
to a virtual keyboard with a fixed known layout. This is designed
to work around issues injecting input events on devices whose
built-in keyboard does not have a useful key character map (ie.
when the built-in keyboard is a special function keyboard only.)
Modified several places where events were being synthesized
to use the virtual keyboard.
Removed support for the "qwerty" default layout.
The new default layout is "Generic". For the most part "qwerty"
was being used as a backstop in case the built-in keyboard did
not have a key character map (probably because it was a special
function keypad) and the framework needed to be able to inject
key events anyways. The latter issue is resolved by using the
special VIRTUAL_KEYBOARD device instead of BUILT_IN_KEYBOARD.
Added the concept of a key modifier behavior so that
MetaKeyKeyListener can distinguish between keyboards that use
chorded vs. toggled modifiers.
Wrote more robust key layout and key character map parsers
to enable support for new keyboard features and user installable
key maps.
Fixed a bug in InputReader generating key ups when keys
are released out of sequence.
Updated tons of documentation.
Currently QwertyKeyListener is being used for full keyboards
with autotext and capitalization disabled. This mostly works
but causes some problems with character pickers, etc.
These issues will be resolved in subsequent changes.

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.
