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.

Split out all the UTF-8/16/32 handling code from String8/16 to its own
file to allow better reuse of code.

Added new key maps for external keyboards. These maps are intended to
be shared across devices by inheriting the "keyboards.mk" product
makefile as part of the device's product definition.
One of the trickier changes here was to unwind some code in
MetaKeyKeyListener that assumed that only the low 8 bits of the meta key
state were actually used. The new code abandons bitshifts in favor
of simple conditionals that are probably easier to read anyways.
The special meta key state constants used by MetaKeyKeyListener
are now (@hide) defined in KeyEvent now so as to make it clearer that they
share the same code space even if those codes are not valid for KeyEvents.
The EventHub now takes care of detecting the appropriate key layout
map and key character map when the device is added and sets system
properties accordingly. This avoids having duplicate code in
KeyCharacterMap to probe for the appropriate key character map
although the current probing mechanism has been preserved for legacy
reasons just in case.
Added support for tracking caps lock, num lock and scroll lock and
turning their corresponding LEDs on and off as needed.
The key character map format will need to be updated to correctly support
PC style external keyboard semantics related to modifier keys.
That will come in a later change so caps lock doesn't actually do
anything right now except turn the shiny LEDs on and off...
Added a list of symbolic key names to KeyEvent and improved the toString()
output for debug diagnosis. Having this list in a central place in the
framework also allows us to remove it from Monkey so there is one less
thing to maintain when we add new keycodes.

Add dumpsys integration for the native input dispatcher.
Add some InputDevice API stubs.
Add an appendFormat helper method to String8 for printf style
string formatting mainly for debugging purposes.
Use generic ArrayList<WindowState> everywhere in WindowManagerService
to eliminate unnecessary casts all over.

Fix some small static-initialization-order issues (and a static-
initializers-missing issue) that result from doing so. The static
libraries don't actually get used for anything real at the moment --
they're used for perf tests of bug 2660235.

Allows the use of UTF-8 for packing resources instead of the
default of UTF-16 for Java. When strings are extracted from the
ResStringPool, they are converted to UTF-16 and the result is
cached for subsequent calls.
When using aapt to package, add in the "-8" switch to pack the
resources using UTF-8. This will result in the value, key, and
type strings as well as the compiled XML string values taking
significantly less space in the final application package in
most scenarios.
