Convert getresuid, getresgid, getuid, geteuid, getgid, getegid

Convert struct cred kuids and kgids into userspace uids and gids when
returning them.

These s390 system calls slipped through the cracks in my first
round of converstions :(

Don't make the security modules deal with raw user space uid and
gids instead pass in a kuid_t and a kgid_t so that security modules
only have to deal with internal kernel uids and gids.

Use kuid's in the IMA rules.

When reporting the current uid in audit logs use from_kuid
to get a usable value.

Note sysctl_hugetlb_shm_group can only be written in the root user
in the initial user namespace, so we can assume sysctl_hugetlb_shm_group
is in the initial user namespace.

Now that the type changes are done, here is the final set of
changes to make the quota code work when user namespaces are enabled.

Small cleanups and fixes to make the code build when user namespaces
are enabled.

Convert w_dq_id to be a struct kquid and remove the now unncessary
w_dq_type.

This is a simple conversion and enough other places have already
been converted that this actually reduces the code complexity
by a little bit, when removing now unnecessary type conversions.

Change struct dquot dq_id to a struct kqid and remove the now
unecessary dq_type.

Make minimal changes to dquot, quota_tree, quota_v1, quota_v2, ext3,
ext4, and ocfs2 to deal with the change in quota structures and
signatures.  The ocfs2 changes are larger than most because of the
extensive tracing throughout the ocfs2 quota code that prints out
dq_id.

quota_tree.c:get_index is modified to take a struct kqid instead of a
qid_t because all of it's callers pass in dquot->dq_id and it allows
me to introduce only a single conversion.

The rest of the changes are either just replacing dq_type with dq_id.type,
adding conversions to deal with the change in type and occassionally
adding qid_eq to allow quota id comparisons in a user namespace safe way.
