We recently fixed the cifs readdir code so that it saves the resume key
before calling CIFSFindNext. Unfortunately, this assumes that we have
just done a CIFSFindFirst (or FindNext) and have resume info to save.
This isn't necessarily the case. Fix the code to save resume info if we
had to reinitiate the search, and after a FindNext.
This fixes connectathon basic test6 against NetApp filers.

When we do a seekdir() or equivalent, we usually end up doing a
FindFirst call and then call FindNext until we get to the offset that we
want. The problem is that when we call FindNext, the code usually
doesn't have the proper info (mostly, the filename of the entry from the
last search) to resume the search.
Add a "last_entry" field to the cifs_search_info that points to the last
entry in the search. We calculate this pointer by using the
LastNameOffset field from the search parms that are returned. We then
use that info to do a cifs_save_resume_key before we call CIFSFindNext.
This patch allows CIFS to reliably pass the "telldir" connectathon test.

When mounting a share with posix extensions disabled,
cifs_get_inode_info turns off all the write bits in the mode for regular
files if ATTR_READONLY is set. Directories and other inode types,
however, can also have ATTR_READONLY set, but the mode gives no
indication of this.
This patch makes this apply to other inode types besides regular files.
It also cleans up how modes are set in cifs_get_inode_info for both the
"normal" and "dynperm" cases.

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.

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.

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.

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
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.
Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.

cifs should not be overwriting an element of the aops structure, since the
