The original attempt missed the fact that Print is a member function,
so the first argument is the implicit 'this'.

The default recovery UI will reboot the device when the power key is
pressed 7 times in a row, regardless of what recovery is doing.
Disable this feature during package installation, to minimize the
chance of corrupting the device due to a mid-install reboot.  (Debug
packages can explicitly request that the feature be reenabled.)

Also provide a default implementation of CheckKey that's reasonable
for many devices (those that have power and volume keys).

In order to support multi-stage recovery packages, we add the
set_stage() and get_stage() functions, which store a short string
somewhere it can be accessed across invocations of recovery.  We also
add reboot_now() which updater can invoke to immediately reboot the
device, without doing normal recovery cleanup.  (It can also choose
whether to boot off the boot or recovery partition.)

If the stage string is of the form "#/#", recovery's UI will be
augmented with a simple indicator of what stage you're in, so it
doesn't look like a reboot loop.

Recovery changes:

- add a method to the UI class that is called when a key is held down
  long enough to be a "long press" (but before it is released).
  Device-specific subclasses can override this to indicate a long
  press.

- do color selection for ScreenRecoveryUI's menu-and-log drawing
  function.  Subclasses can override this to customize the colors they
  use for various elements.

- Include the value of ro.build.display.id in the menu headers, so you
  can see on the screen what version of recovery you are running.

NextCheckKeyIsLong() is called right before each call to CheckKey() to
tell the implementation if the key is a long-press or not.  (To be
used on devices with few buttons.)  It's done as a separate method
(rather than a parameter to CheckKey) to not break existing recovery
UI implementations.

EnqueueKey() can be called from CheckKey() to put arbitrary code codes
in the synchronous queue (to be processed by HandleMenuKey).

Add images of text for all locales we support.  Make the progress bar
fill the correct way for RTL languages.  (Flip the direction the
spinner turns, too, just for good measure.)

- 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.

Replace the device-specific functions with a class.  Move some of the
key handling (for log visibility toggling and rebooting) into the UI
class.  Fix up the key handling so there is less crosstalk between the
immediate keys and the queued keys (an increasing annoyance on
button-limited devices).

Move all the functions in ui.c to be members of a ScreenRecoveryUI
class, which is a subclass of an abstract RecoveryUI class.  Recovery
then creates a global singleton instance of this class and then invoke
the methods to drive the UI.  We use this to allow substitution of a
different RecoveryUI implementation for devices with radically
different form factors (eg, that don't have a screen).

When installing a package, create /cache/recovery/last_install, which
contains the filename of the package and a 1 or 0 for success or
failure.

Also, don't mount ext4 and vfat filesystems as read-only (on devices
where /cache is ext4, we need it to be read-write).

Change some of the UI parameters (# of indeterminate progress bar
frames, fps, etc.) from #defined constants to variables that can be
set by the device-specific recovery_ui code (via a new function).

Support overlaying different images on top of the base installation
icon to animate it.  Make the FPS control more accurate.

If recovery sits for 2 minutes in prompt_and_wait(), and you've never
turned the screen on via the magic keypress, go ahead and reboot.  (We
used to assume that the user could pull the battery to get out of this
state, but on devices with nonremovable batteries...)

If you've ever enabled display of the log/menu since recovery started,
we assume you know what you're doing and will stay in recovery until
you choose to reboot.

Remove the wacky notion of "roots" and "root paths" (those things that
look like "FOO:some/path" instead of just "/foo/some/path").  Let each
device specify its own table of available partitions and how to mount
them (needed for devices that use both MTD/yaffs2 and EMMC/ext4
partitions).

Make the mount and format functions take extra parameters describing
the filesystem type and add support for mounting and formatting ext4
filesystems on EMMC.

Change recovery to consistently use stdout for status messages instead
of mixing stdout and stderr.

displays a menu of zip files (and subdirs) on the sdcard and lets you
pick which one to install.

Reduce the fraction of the progress bar used for package verification
from 50% to 25%:
  - verification is faster than before due to sha1 improvements
  - in eclair we're now verifying the compressed data rather than
    decompressing it
  - incremental packages (which is what most installs use) write more
    data than is contained in the package.

To do a firmware-install-on-reboot, the update binary tells recovery
what file to install before rebooting.  Let this file be specified as
"PACKAGE:<foo>" to indicate taking the file out of the OTA package,
avoiding an extra copy to /tmp.  Bump the API version number to
reflect this change.
