Switch to a Wear-like intro/loop system. We don't have an intro yet,

Unlike them, we don't hard-code the number of frames: we just look to
see what we have available. We do hard-code the fps though.
Also add a graphics test mode so you can see a demo of the UI components
without having to actually apply an OTA.

more useful to show _some_ text if we don't have a locale (which should

The recovery system behaves a little bit differently on userdebug or
eng builds by presenting error reports to the user in the ui.
This is controlled by checking the build fingerprint for the string
:userdebug/ or :eng/. But with AOSP version numbers most AOSP
builds blows the 92 char limit of ro.build.fingerprint and therefore
the property is not set, so this condition will always be evaluated
to false, for most builds.
Instead of depending on the flaky ro.build.fingerprint this change
uses ro.debuggable.

Implement a new method of sideloading over ADB that does not require
the entire package to be held in RAM (useful for low-RAM devices and
devices using block OTA where we'd rather have more RAM available for
binary patching).
We communicate with the host using a new adb service called
"sideload-host", which makes the host act as a server, sending us
different parts of the package file on request.
We create a FUSE filesystem that creates a virtual file
"/sideload/package.zip" that is backed by the ADB connection -- users
see a normal file, but when they read from the file we're actually
fetching the data from the adb host. This file is then passed to the
verification and installation systems like any other.
To prevent a malicious adb host implementation from serving different
data to the verification and installation phases of sideloading, the
FUSE filesystem verifies that the contents of the file don't change
between reads -- every time we fetch a block from the host we compare
its hash to the previous hash for that block (if it was read before)
and cause the read to fail if it changes.
One necessary change is that the minadbd started by recovery in
sideload mode no longer drops its root privileges (they're needed to
mount the FUSE filesystem). We rely on SELinux enforcement to
restrict the set of things that can be accessed.

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

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.

At load_locale_from_cache() function, LOCALE_FILE must get closed
after it is opened and used. Otherwise it causes a failure to
unmount "/cache" after load_locale_from_cache() function is called.

We need prompt_with_wait() to show either the ERROR or NO_COMMAND
state as appropriate.

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.)

- change locale filename to "last_locale" so the main system doesn't
delete it
- clean up some chatty logging
- update images with real German (other languages TBD)

- 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.

- add the --just_exit option to make recovery exit normally without doing anything
- make it possible to build updater extensions in C++
- add the clear_display command so that the updater binary can request
recovery switch to the NONE background UI
These are all used to support the notion of using OTA as a factory
reflash mechanism.

The contribution of SELinux things to AOSP had a call to the old
ui_print that merged cleanly. This changes that call into the newer
call so it will actually compile when enabled.

Rather than depending on the existence of some place to store a file
that is accessible to users on an an unbootable device (eg, a physical
sdcard, external USB drive, etc.), add support for sideloading
packages sent to the device with adb.
This change adds a "minimal adbd" which supports nothing but receiving
a package over adb (with the "adb sideload" command) and storing it to
a fixed filename in the /tmp ramdisk, from where it can be verified
and sideloaded in the usual way. This should be leave available even
on locked user-build devices.
The user can select "apply package from ADB" from the recovery menu,
which starts minimal-adb mode (shutting down any real adbd that may be
running). Once minimal-adb has received a package it exits
(restarting real adbd if appropriate) and then verification and
installation of the received package proceeds.
always initialize usb product, vendor, etc. for adb in recovery
Set these values even on non-debuggable builds, so that the mini-adb
now in recovery can work.

Move the key for handling keys from ScreenRecoveryUI to RecoveryUI, so
it can be used by devices without screens. Remove the UIParameters
struct and replace it with some new member variables in
ScreenRecoveryUI.

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).
