MS-SMB2 Section 2.2.31 lists fsctls.  Update our list of valid
cifs/smb2/smb3 fsctls and some related structs
based on more recent version of docs.  Additional detail on
less common ones can be found in MS-FSCC section 2.3.

CopyChunk (server side copy, ie refcopy) will depend on a few

The new Windows update supports SMB3.02 dialect, a minor update to SMB3.
This patch adds support for mounting with vers=3.02

Based on whether the user (on mount command) chooses:

vers=3.0 (for smb3.0 support)
vers=2.1 (for smb2.1 support)
or (with subsequent patch, which will allow SMB2 support)
vers=2.0 (for original smb2.02 dialect support)

send only one dialect at a time during negotiate (we
had been sending a list).

Since both CIFS and SMB2 use ses->capabilities (server->capabilities)
field but flags are different we should make such checks protocol
independent.

Add mapping table for 32 bit SMB2 status codes to linux errors.
Note that SMB2 does not use DOS/OS2 errors (ever) so mapping to
DOS/OS2 errors as a common network subset (as we do for cifs)
doesn't help. And note that the set of status codes is much more
complete here.
