Improve support for external keyboards.
Use Vendor ID, Product ID and optionally the Version to
locate keymaps and configuration files for external devices.
Moved virtual key definition parsing to native code so that
EventHub can identify touch screens with virtual keys and load
the appropriate key layout file.
Cleaned up a lot of old code in EventHub.
Fixed a regression in ViewRoot's fallback event handling.
Fixed a minor bug in FileMap that caused it to try to munmap
or close invalid handled when released if the attempt to map
the file failed.
Added a couple of new String8 conveniences for formatting strings.
Modified Tokenizer to fall back to open+read when mmap fails since
we can't mmap sysfs files as needed to open the virtual key
definition files in /sys/board_properties/.

Added support for full PC-style keyboards.
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.
