63a4e88358 smbd: split out POSIX info_levels from smbd_do_setfilepathinfo() into own function
smbd_do_setfilepathinfo() can be made fully handle based for all non-POSIX
infolevels with pathref fsps, but for a POSIX create we may not have a fsp if
the path points at a symlink.

Splitting the POSIX from the non-POSIX logic allows for cleaner handling of this
in the future with pathref fsps.

71a5759623 smbd: base POSIX semantics of call_trans2findfirst() on SMB_FILENAME_POSIX_PATH flag

42b8a431f0 smbd: base POSIX semantics in call_trans2findfirst() on req->posix_pathnames
This will require a SMB1 client to enable SMB1 POSIX extensions, just sending
POSIX info-level requests without first enabling them won't cut it.

As discussed with Jeremy, SMB1 POSIX extensions is a global thing and the client
that wants to use it is expected to enable them explicitly before making use of
POSIX info-levels.

f75e633fde s3: smbd: Add a 'const char *src_orginal_lcomp' (last component) parameter to rename_internals().
Not yet used. Passing as NULL means explicitly no wildcards
in the source name. There's only one place where we have to handle
wildcards here and that is from SMB1 reply_mv().

Could have used a bool here as in unlink_internals() but
using a string here makes the parameters more symmetrical
around src and destination values.

322574834f vfs: remove dirfsp arg from SMB_VFS_CREATE_FILE()
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.

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
