[PATCH v4 00/14] Clean up mount functions

[bjschuma@netapp.com]

From: Bryan Schumaker <bjschuma@netapp.com>

I noticed that we had 5 almost identical mount functions in super.c.  I
collapsed them all into one common function to make everything easier to
maintain and work with.  Patches 1 - 4 are cleanups, 5 - 8 drop us down to
one common mount path, and 9 - 14 are cleanups to remove the nfs4_mount()
function.

These patches also help simplify my modules changes since I no longer have
to split these functions out of the generic code.

Changes in v4
-------------
- Fix up the commit message on patch 6
- Don't delete the dprintks saying that the nfs_xdev_mount() function is exiting

Changes in v3
-------------
- Remove the NFS4_MOUNT_UNSHARED flag
- nfs_validate_mount_data() selects between the v2/3 function and the v4 function
- Created a generic function for parsing text mount data

Comments or suggestions are appreciated!
