Touch: slot and tracking updates

Discard type A MT slots if type B MT tracking ID sent: Some devices send
an initial ABS_MT_SLOT event before switching to type B events, so
discard any type A state related to slot.

Track whether ABS_MT_TRACKING_ID was seen in the current sequence to
differentiate between vkeys and hardware keys.

fix unnecessarily slow writing of EMMC partitions

These were attempts to write partitions "conservatively" in hopes of
fixing the problems with writing the radio partition on Nexus 4.  They
didn't work (a kernel patch was needed), but got left in.  They make
writing of partitions unnecessarily slow (ie, we really shouldn't need
to sync() after every 4kb).  Roll back most of them, but leave the
verification read-back in.

Tell vold to use the fstype defined in fstab when formatting

If, for whatever reason, a voldmanaged volume had a different filesystem
than the one defined in the fstab, then this filesystem was kept when
formatting. Change the logic to use the filesystem defined in the fstab when
available.

Fix BOARD_RECOVERY_BLDRMSG_OFFSET CFLAG

Including BOARD_RECOVERY_BLDRMSG_OFFSET in BOARD_RECOVERY_DEFINES turns
the define into a string. We need BOARD_RECOVERY_BLDRMSG_OFFSET to be an
int.

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.
