Fixes two problems:
1) we dropped down to negotiating lanman if we did not recognize the
mechanism (krb5 e.g.)
2) we did not stop cifsd (thus will fail when doing rmod cifs with
slab free errors) when we fail tcon but have a bad session (which is
the case in which signing is required but we don't allow signing on
the client)
It also turns on extended security flag in the header when passing
"sec=krb5" on mount command (although kerberos support is not done of
course)

This should be the last big batch of whitespace/formatting fixes.
checkpatch warnings for the cifs directory are down about 90% and
many of the remaining ones are harder to remove or make the code
harder to read.

We were checking the wrong (old) global variable to determine
whether to override server and force signing on the SMB
connection.

require such support. Also includes support for setting security
flags for cifs. See fs/cifs/README

New cifs_writepages routine was not updated bytes written in cifs stats.
Also added ability to clear /proc/fs/cifs/Stats by writing (0 or 1) to it.

These changes to debug code and new stats are helpful in
debugging potential tcp performance/configuration problems under cifs.

unless response is larger than 256 bytes. This cuts more than 1/3 of
the large memory allocations that cifs does and should be a huge help to
memory pressure under stress.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
