This changes sdcardfs to modify the user and group in the
underlying filesystem depending on its usage. Ownership is
set by Android user, and package, as well as if the file is
under obb or cache. Other files can be labeled by extension.
Those values are set via the configfs interace.
To add an entry,
mkdir -p [configfs root]/sdcardfs/extensions/[gid]/[ext]

Only included the source code as is for kernel 3.0. Following patches
take care of porting this file system to version 3.10.
