vold: mount ext4 with forced SELinux context

Always mount voldmanaged ext4 partitions with the SELinux sdcard_external
context. For other file systems, this is done via the genfs_context,
but since ext4 supports SELinux natively, it must be set here.

vold: force SELinux context only for sdcard

Google uses this code to mount ASEC as well and we shouldn't force
their SELinux contexts

vold: allow non-vfat devices to be used as ASEC

CM supports alternative file systems (which some devices specify
in the fstab as 'auto').

vold: don't crash when formatting unformatted volume

When formatting unformatting volumes, fstype will be NULL causing
a crash in strcmp. Set it to "vfat" to avoid the crash.

vold: Allow specifying the filesystem type when formatting

 * Optional parameter added to "volume format" to specify the filesystem
   type to use. If not specified, default is to auto-detect.
