Isolate the code that interacts with fbdev, in preparation for adding
a new backend.

Recovery now draws directly to the framebuffer by rolling its own
graphics code, rather than depending on libpixelflinger.
The recovery UI is modified slightly to eliminate operations that are
slow with the software implementation: when the text display / menu is
turned on, it now appears on a black background instead of a dimmed
version of the recovery icon.
There's probably substantial room for optimization of the graphics
operations.

Instead of one 'base' installing image and a number of overlay images
that are drawn on top of it, we represent the installing animation
with one PNG that contains all the animation frames, interlaced by
row. The PNG is expected to have a text chunk with the keyword
'Frames' and a value that's the number of frames (as an ascii
string). This representation provides better compression, removes the
need to subclass ScreenRecoveryUI just to change the position of the
overlay or number of frames, and doesn't require gr_blit() to support
an alpha channel.
We also remove the 'indeterminate' progress bar used when wiping data
and/or cache. The main animation serves the same purpose (showing
that the device is still alive); the spinning progress bar has been
redundant for a while.
This changes the default recovery animation to include the
antenna-wiggling and gear-turning that's used in the Nexus 5 recovery
animation.

Get rid of the notion of a font's "ascent"; the reference point for
drawing is the top-left corner of the character box rather than the
baseline. Add some more space between the menu entries and make the
highlight bar around the text.
Replace the default font.png with two images; the build system will
include one or the other based on the resolutions of the device.
Restore the original compiled-in bitmap font, to fall back on when
font.png can't be found (eg, in the charger binary).
Add support for bold text (when a font.png image is used).

If your screen is a TV, it may not actually be displaying the edges of
the framebuffer. Allow specifying an overscan percentage, and move
each edge of the framebuffer in by that percent of the width/height.
(The gr_* layer just lies to the caller about the size of the
framebuffer, telling the caller it's smaller than it really is, and
offsets all drawing commands to match.)

- recovery takes a --locale argument, which will be passed by the main
system
- the locale is saved in cache, in case the --locale argument is
missing (eg, when recovery is started from fastboot)
- we include images that have prerendered text for many locales
- we split the background states into four (installing update,
erasing, no command, error) so that appropriate text can be shown.

If a key is down prior to the time of initialization, we would not get the
down event for the key, and thus think that the key is not pressed.
Add an interface that allows one to provide a callback to execute
on all keys that are currently down.

Events are now delivered through a callback mechanism during
a call to ev_dispatch(). This will allow us to extend the events
code to handle other devices/fds, not just input. One such example
is the ability to process uevents.
During initialization, we provide an input callback to ev_init
that gets called when a new event is encountered during dispatch.
ev_get has been removed and replaced with ev_get_input() helper
function that can be called from inside the callback to attempt
to get an input event.
The existing client of ev_get in recovery has been split up such
that the input thread just calls ev_wait(); ev_dispatch(); and
the input_callback handles individual events by using the
ev_get_input() helper.

Take some device-specific details of the recovery UI (eg, what keys to
press to bring up the interface and perform actions, exact text of the
menu, etc.) and split them out into separate C functions. Arrange to
take implementations of those functions from the appropriate vendor
directory at build time. Provide a default implementation in case no
vendor-specific one is available.
