Fix issue where android device manager, etc, dont actually wipe data.

--wipe_data issues via /cache/recovery/command will now completely format data.

All other manual wipe commands will preserve data on /data/media.
There is another mounts/storage option that will do a true data format.

recovery: Only install adb keys once

 * Recovery is currently calling setup_adbd when the process starts to
   fetch the keys from the data partition and (re)start adbd.
 * This of course has the heinous side effect of making it
   impossible to use gdbserver to debug recovery, making me a sad panda.
 * Make setup_adbd a pseudo-binary, and run it as a oneshot service
   instead.

recovery: Revenge of MiniVold

 * Vold has been refactored to be friendly to an environment such as
   recovery. Using Vold will eliminate many hacks and add previously
   unavailable features.
 * Link with libminivold and create a pseudo-binary to launch as a
   service in recovery.
 * Libvoldclient is an event-driven client for controlling the daemon.
 * Handles device hotplug and automatic mounting, if desired.
 * Manages USB storage
 * Can check and format volumes using any supported filesystem
 * Dynamically generate all storage paths
 * Dynamically refresh menus affected by storage changes
 * Fixed wall-of-compile-warnings and const-correctness in extendedcommands.c
 * Misc cleanups
 * Say goodbye to "apply /sdcard/update.zip". You have served us well.

recovery: Don't enable UMS function unless needed

 * This causes problems with some hosts. Only enable the composition if
   the user actually turns UMS on.
