Add CM SELinux policies

All credit goes to CM and those who contributed!

Add SELinux filesystem relabeling to init

Since not all recoveries out there will support the OTA packages'
own labeling, check at boot if the system needs labels (and
apply them)

sepolicy: Start CM Common sepolicy

Rather than having to maintain out of tree changes, it is often
easier to maintain a hiearchy of changes, starting with the vendors
common config file. From there, inheriting products can pick up a base
and start to add or remove certain bits from it, making use of the
BOARD_SEPOLICY_* functions documented in external/sepolicy/README.

sepolicy: allow vold to create files on external sdcard

This is required for ASEC support. Vold can already create and
access directories, but do not yet have the permission for files.

sepolicy: allow vold to mount ext4 sdcard

When vold mounts an ext4 sdcard, it needs to force the context to
sdcard_external.
