getting the parent dir name (smb_fname->base_name).

Simplify by using parent_dirname() to split the path

b74653f2cd smbd: add twrp arg to synthetic_smb_fname()
Most places take twrp from a local struct smb_filename variable that the
function is working on. Some don't for various reasons:

o synthetic_smb_fname_split() is only called in very few places where we don't
  expect twrp paths

o implementations of SMB_VFS_GETWD(), SMB_VFS_FS_CAPABILITIES() and
  SMB_VFS_REALPATH() return the systems view of cwd and realpath without twrp info

o VFS modules implementing previous-versions support (vfs_ceph_snapshots,
  vfs_shadow_copy2, vfs_snapper) synthesize raw paths that are passed to VFS NEXT
  functions and therefor do not use twrp

o vfs_fruit: macOS doesn't support VSS

o vfs_recycle: in recycle_create_dir() we need a raw OS path to create a directory

o vfs_virusfilter: a few places where we need raw OS paths

o vfs_xattr_tdb: needs a raw OS path for SMB_VFS_NEXT_STAT()

o printing and rpc server: don't support VSS

o vfs_default_durable_reconnect: no Durable Handles on VSS handles, this might
  be enhances in the future. No idea if Windows supports this.

o get_real_filename_full_scan: hm.... FIXME??

o get_original_lcomp: working on a raw path

o msdfs: doesn't support VSS

o vfs_get_ntquota: synthesizes an smb_filename from ".", so doesn't support VSS
  even though VFS modules implement it

o fd_open: conn_rootdir_fname is a raw path

o msg_file_was_renamed: obvious

o open_np_file: pipes don't support VSS

o Python bindings: get's a raw path from the caller

o set_conn_connectpath: raw path

o set_conn_connectpath: raw path

o torture: gets raw paths from the caller

69691dd0cd smbd: fix handling of sentinel timestamp values
This implements two core changes:

* use NTTIME instead of struct timespec at the database layer

* use struct timespec { .tv_nsec = SAMBA_UTIME_OMIT } as special sentinel
  value in smbd when processing timestamps

Using NTTIME at the database layer is only done to avoid storing the special
struct timespec sentinel values on disk. Instead, with NTTIME the sentinel value
for an "unset" timestamp is just 0 on-disk.

The NTTIME value of 0 gets translated by nt_time_to_full_timespec() to the
struct timespec sentinel value { .tv_nsec = SAMBA_UTIME_OMIT }.

The function is_omit_timespec() can be used to check this.

Beside nt_time_to_full_timespec(), there are various other new time conversion
functions with *full* in their name that can be used to safely convert between
different types with the changed sentinel value.

4736623c24 s3: rename talloc_sub_advanced() to talloc_sub_full()
We currently have the following substitution functions:

  talloc_sub_basic()
  talloc_sub_advanced()

talloc_sub_basic() currently substitutes a subset of talloc_sub_advanced().

We'll need a function X that only substitutes what talloc_sub_advanced()
substitutes *without* what talloc_sub_basic() does.

To get there rename talloc_sub_advanced() to talloc_sub_full(). A subsequent
commit will then bring back talloc_sub_advanced() as described above.

Examples with fictional replacement letters A and B. Currently:

  talloc_sub_basic:    A
  talloc_sub_advanced: AB

New:

  talloc_sub_basic:    A
  talloc_sub_advanced:  B
  talloc_sub_full:     AB

NOTE: Many of the users of this structure should be reviewed, as unix
