ADB sideload command not work

In kernel(3.10) USB ADB gadget driver is removed.
Using Functionfs for USB adb gadget.

Android recovery uses a stripped down version
of adb command for sideload only. It's missing
the ffs function support, so add the ffs
support to allow sideload command to work

recovery: Fix adb with linux 3.10

In kernel 3.10, f_adb has been removed and adbd can use functionfs
instead. Mount functionfs on boot for adbd. On older kernels, mount
will fail silently and adbd will revert to f_adb.

Remove extra slashes from zip path in openrecovery

TWFunc::Get_Path() returns a path with a trailing slash and the substr
method is returning a string with a leading slash, so we don't need to
specify additional slashes for wholePath in Locate_Zip_File().

Also, put 'value' readout to log on its own line if it exists.

applypatch: add support for BML partitions

This actually uses the EMMC partition access code. In order for this
to work, the BML partition name is changed back to the block
device name (e.g. "boot" -> "/dev/block/bml9"), and the
BML_UNLOCK_ALL ioctl is called before writing.

Update RECOVERY_VARIANT blocking to use project-path-for

Using RECOVERY_VARIANT to allow recovery to reside at
bootable/recovery-(variant) has changed at CM. project-path-for now
handles all the path re-mapping. This is simply a compatibility update
to be able to continue using RECOVERY_VARIANT with TWRP in a CM tree.

performance profile support

Many device trees support the recovery.perf.mode property to
set various core frequencies and online/offline mode. TWRP is
highly threaded, and support for multiple cores on many operations
dramatically recudes the time, e.g., backups, zip flashes, etc.
