New mount/format capabilities function for Mounts menu

This is largely a re-factoring of the code to populate the mountable and
formattable partitions on the "Mounts and Storage Menu". The if/else
logic is replaced by a mount/format capabilities function with
pre-defined logic for some fs_types and /partitions. This should be much
easier to maintain.

The original ro.cwm.forbid_format property is still supported, though it
is no longer necessary to include any of
 /misc  /radio  /bootloader  /recovery  /efs  /wimax
in the property as they are by default always excluded from the
mountable and formattable partitions.

A new property ro.cwm.forbid_mount is introduced to always exclude
partitions from the mountable partitions.

Example:
 ro.cwm.forbid_format="/firmware,/whatevs"
 ro.cwm.forbid_mount="/firmware,/blah"

Result:
 /firmware will be excluded as either mountable or formattable
 /whatevs will be excluded as formattable, but still is mountable
 /blah will be excluded as mountable, but is still formattable

recovery: add overlay interface for recovery mode

Pan display needs FB allocation from driver and
since it is removed from driver, switching to overlay
interfaces in recovery mode. Basically forking out
the overlay and pan_display path in separate files.
