8a19314132 vfs_ceph: add empty ACL callbacks
If a vfs module has no ACL callbacks, smbd will use its default ACL
callbacks. These default ACL callbacks operate on local filesytem,
it's clearly wrong for ceph case.

libcephfs does not support ACL yet, so this patch adds ACL callbacks
that do nothing.

628fa5bc00 vfs_ceph: use 'file descriptor' version xattr functions when possible
libcephfs version 0.94 adds 'file descriptor' version xattr functions.
This patch makes corresponding samba VFS callbacks use these new
functions.

7551a4edb5 vfs_ceph: remove cephwrap_init_stat_ex_from_stat()
cephwrap_init_stat_ex_from_stat() lacks code that makes 'create'
timestamp. Besides that, it's identical to init_stat_ex_from_stat().

12c0b6bf40 s3/vfs: change fallocate mode flags from enum->uint32_t
The Linux fallocate syscall offers a mode parameter which can take the
following flags:
FALLOC_FL_KEEP_SIZE
FALLOC_FL_PUNCH_HOLE (since 2.6.38)
FALLOC_FL_COLLAPSE_RANGE (since 3.15)
FALLOC_FL_ZERO_RANGE (since 3.14)

The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified
alongside FALLOC_FL_KEEP_SIZE.

Samba currently takes a vfs_fallocate_mode enum parameter for the VFS
fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This
commit changes the fallocate hook such that it accepts a uint32_t flags
parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.

41c4666a72 s3/vfs: remove unused SMB_VFS_DISK_FREE() small_query parameter
The small_query parameter for SMB_VFS_DISK_FREE() was, prior to the
previous commit, used to obtain 16-bit wide free-space information for
the deprecated dskattr SMB_COM_QUERY_INFORMATION_DISK command.

With the dskattr handler now performing the 16-bit collapse directly,
the small_query parameter can be removed from the entire code path.

301a1f9192 Implements a vfs module for cephfs, a distributed file system
with posix semantics, built on the ceph distributed object
storage layer.  The ceph vfs module interfaces to the libcephfs
userspace API, and is primarily a lightweight wrapper around
libcephfs, translating error codes and parameters as necessary.
