Make minadbd drop its root privileges after initializing. We need to
make the /tmp directory writable by the shell group so that it can
drop the sideloaded file there.
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).

updater now has a function "wipe_cache();" which causes recovery to
wipe the cache partition after the successful installation of the
package. Move log copying around a bit so logs and the last_install
flag file are copied to cache after it's wiped.

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.

Wrote some missing items in recovery, most notably the serial number so that it shows up correctly on adb.

Always start adbd if ro.debuggable=1 rather than basing it on user preference
in persistent system properties.
Use new D001 product ID, which I just allocated for "android recovery mode"

When the misc partition is on an emmc device, recovery can get started
and try to access it before the kernel has actually created the
device. Try statting the device before reading or writing it; delay
up to 10 seconds waiting for the device to exist.
