session when multiply mounted.

Fixes slow response when cifs client is mounted to shares on multiple
servers and oplock break occurs (usually due to attempt to multiply open a
file).  When treeids on mutiple mounted shares match and we find the wrong
match first, we searched for the wrong cached files to send oplock break
response for which usually meant that no matching file was found and thus
the server would have to timeout the notification.  Oplock break timeout is
about 20 seconds on some servers so this could cause significantly slower
performance on file open calls in a few cases (in particular when multiple
shares are mounted from multiple servers, tree ids match, and we have a
cached file which is later opened multiple times).  This was the most
important of the bugs that was found and fixed at Connectathon
(interoperability testing event) this week.

The cifs session setup code has three cases, and a fourth for backlevel
LANMAN2 style session setup needed to be added.  This new session setup
implmentation will eventually replace the other three and should be
easier to read while fixing a few minor problems (not setting
the LARGE READ/WRITEX flags when NTLMSSP was negotiated for example) and
adding support for NTLMv2 (which will be added with the next patch. In the
meantime, this code is marked in an CONFIG_CIFS_EXPERIMENTAL block and will
not be turned on by default until it is tested against more server types.

Forgetting to set wsize on the mount command costs more than 10% on large
write (can be much more) so this makes a saner default.  We still shrink
this default smaller if server can not support it.
