Steve French 77c57ec896 [CIFS] don't explicitly do a FindClose on rewind when directory search has ended
Do the following series of operations on a CIFS share:

    opendir(dir)
    readdir(dir)
    unlink(file in dir)
    rewinddir(dir)
    readdir(dir)

If the readdir read all entries in the directory this will make CIFS throw an error like this:

     CIFS VFS: Send error in FindClose = -9

CIFS requests "Close at end of search" of the server by setting this bit when issuing FindFirst or FindNext.  Therefore when all search entries are returned, the server may return "end of search" and close the search implicitly when this bit is set by the client on the request.  We check for this when a readdir is explicitly closed - but when the client notices that a directory has changed after the last operation, we attempt to close the directory before reopening by reissuing a second FindFirst. But, the directory may already been implicitly closed (due to end of search) because the first readdir finished. So we only want to issue a FindClose call in this case when we don't expect it to already be closed.

Steve French 90c81e0b0e [CIFS] clean up some hard to read ifdefs
Christoph had noticed too many ifdefs in the CIFS code making it
hard to read.  This patch removes about a quarter of them from
the C files in cifs by improving a few key ifdefs in the .h files.

Steve French a6f8de3d9b [CIFS] Fix stale mode after readdir when cifsacl specified
When mounted with cifsacl mount option, readdir can not
instantiate the inode with the estimated mode based on the ACL
for each file since we have not queried for the ACL for
each of these files yet.  So set the refresh time to zero
for these inodes so that the next stat will cause the client
to go to the server for the ACL info so we can build the estimated
mode (this means we also will issue an extra QueryPathInfo if
the stat happens within 1 second, but this is trivial compared to
the time required to open/getacl/close for each).

ls -l is slower when cifsacl mount option is specified, but
displays correct mode information.

Steve French 4523cc3044 [CIFS] UID/GID override on CIFS mounts to Samba
When CIFS Unix Extensions are negotiated we get the Unix uid and gid
owners of the file from the server (on the Unix Query Path Info
levels), but if the server's uids don't match the client uid's users
were having to disable the Unix Extensions (which turned off features
they still wanted).   The changeset patch allows users to override uid
and/or gid for file/directory owner with a default uid and/or gid
specified at mount (as is often done when mounting from Linux cifs
client to Windows server).  This changeset also displays the uid
and gid used by default in /proc/mounts (if applicable).

Also cleans up code by adding some of the missing spaces after
"if" keywords per-kernel style guidelines (as suggested by Randy Dunlap
when he reviewed the patch).

This eliminates the i_blksize field from struct inode.  Filesystems that want
