Similar to the header files, libgpfs_gpl.so no longer exists. The
library is now always called libgpfs.so.

gpfs_gpl.h no longer exists, everything from that header file has been
merged to gpfs.h. gpfs_fcntl.h implicitly includes gpfs.h. Simplify the
code by only looking for gpfs_fcntl.h and including that file.

The gpfs_set_times API call allows setting timestamps directly in GPFS
without going through the utime() call. Using this API call fixes an
unecessary oplock break when a client sends a SET_FILE_ALLOCATION_INFO
request and no other client has opened the file. The call to utime()
triggers the oplock break through the Linux kernel. Using the
gpfs_set_times call for updating the timestamp avoids the call to
utime() and the oplock break.

The query of the fileset quota needs to determine the file set id first.
With the currently available interface, this requires opening the file
to get a file descriptor. For files, this open can fail when a share
mode is set.
Workaround this by querying the fileset id on the directory instead.
The proper solution would be getting an interface for getting the
fileset id that does not require opening the file.

Fix this compile error by adding fcntl.h as a include that defines F_RDLCK
and F_WRLCK:
modules/gpfs.c: In function ‘set_gpfs_lease’:
modules/gpfs.c:102: error: ‘F_RDLCK’ undeclared (first use in this function)
modules/gpfs.c:102: error: (Each undeclared identifier is reported only once
modules/gpfs.c:102: error: for each function it appears in.)
modules/gpfs.c:105: error: ‘F_WRLCK’ undeclared (first use in this function)
GPFS provides the gpfs_prealloc call. Implement the fallocate
callback with mode VFS_FALLOCATE_EXTEND_SIZE using this call.
There is no support for VFS_FALLOCATE_KEEP_SIZE, so report
this mode as not available.
Add the GPFS api calls for reporting the quotas and free space:
- get_gpfs_quota for querying a quota
- get_gpfs_fset_id for mapping a path to a fileset id
when development of vfs_gpfs was started a long time ago it was
considered a good idea to have it compileable even if GPFS is not
around and then the module would complain in the logs that libgpfs
is not there
Nowadays this does not work any more as the code contains GPFS
specific types that need the GPFS header files.
Instead of making it compile again by adding GPFS typedefs, this
removes the whole approach. Other VFS modules also do not even
compile when necessary headers are not around, so do the same for
the GPFS module code.

With newer GPFS releases, libgpfs contains a function
gpfs_lib_init(). It marks the pseudo-device the lib uses
as interface to the GPFS kernel module to not be to
destroyed after each call to GPFS.
This saves us some microseconds creating and removing the device
each time we do a call to libgpfs.

As of GPFS 3.2.1 PTF8 libgpfs will be available as GPL, so we don't need the
special libgpfs_gpl lib anymore. For backwards compatibility with pre-PTF8 GPFS
installations, still look there.
bugs in various places whilst doing this (places that assumed
BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).
