Don't init with 0 just to overwrite again. Probably the compiler will
figure that out anyway, but to me this looks cleaner.

Moved into the VFS as SMB_VFS_PARENT_PATHNAME() to

This was supposed to be a shortcut to avoid passing dirfsp around as an explicit
function argument throughout the whole codebase when the new VFS design idea was
based on using *AT functions throughout the VFS.
Now that we've opted for basing the VFS on handles and *AT functions will only
be used in a much more limitted extent, it makes sense to remove this internal
dirfsp reference, otherwise the combination of internal fsp->dirfsp and
smb_fname->fsp is going to be a tough to wrap your head around.

This looses precision by going from NTTIME to time_t, but GMT_FORMAT only has
seconds granularity anyway and @GMT token as defined by MS-SMB2 as well.

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

Add a new utility functions that checks whether a struct smb_filename points to
a real named stream, excluding the default stream "::$DATA".
foo -> false
foo::$DATA -> false
foo:bar -> true
foo:bar:$DATA -> true

Will be needed when we migrate lower-level VFS functions to
take an struct smb_filename *, especially the SYS_ACL and
XATTR modification modules, as these must ignore a passed-in
