Add support for init mknod command.

This is required for statically allocated devices.
These don't hit ueventd and hence doesn't automatically get a device node.

fs_mgr: support multiple file systems on a mount point

This is a combination of 3 commits pulled from Motorola's github for
allowing f2_mgr to have "fallback" handling for a mount point.  This
is most useful in the case of f2fs where some variants may be formatted
ext4 and some f2fs.  These device can now be supported in 1 fstab.

Example snippet of fstab.* for userdata mount point:
/dev/block/platform/msm_sdcc.1/by-name/userdata    /data        ext4    rw,discard,nosuid,nodev,noatime,nodiratime,noauto_da_alloc,nobarrier    wait,check,encryptable=footer
/dev/block/platform/msm_sdcc.1/by-name/userdata    /data        f2fs    rw,discard,nosuid,nodev,noatime,nodiratime,inline_xattr                 wait,encryptable=footer

Changes in logic ignore 1st failure as an automatic assumption of encryption.
Instead fstab is checked for another line describing mount point (2 retries)
Once all retries fail, encryption is assumed.

NOTE: Some logic was removed from the original sources: If userdata failed to mount
and was not encrypted a format of the filesystem was forced as a way of recovering
the device.  Most custom ROM users have access to recovery where they can decide
what to do in this case.

pixelflinger: use __builtin___clear_cache instead of cacheflush

cacheflush doesn't exist on LP64 any more, and gcc's
__builtin___clear_cache is better in every way.  Use it instead.
