Jeff Brown 6a817e22e4 Add keycodes and meta-key modifiers to support external keyboards.
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.

Android Utility Function Library

If you need a feature that is native to Linux but not present on other
platforms, construct a platform-dependent implementation that shares
the Linux interface.  That way the actual device runs as "light" as
possible.

If that isn't feasible, create a system-independent interface and hide
the details.

The ultimate goal is *not* to create a super-duper platform abstraction
layer.  The goal is to provide an optimized solution for Linux with
reasonable implementations for other platforms.
