conn->origpath is always a duplicate of conn->connectpath.
The only function that sets conn->connectpath is set_conn_connectpath() and
everywhere it's called, there's a subsequent talloc_strdup() into
conn->origpath.

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

Share path definitions don't need to be aware of symlinks.
This is strictly a change in behavior, but the vfs_widelinks
module (if loaded) copes with symlinks in the share definition.

Since 8e81090789 we're doing chdir() twice, first
into conn->connectpath, then into conn->origpath.
Before commit 8e81090789 if
chdir(conn->connectpath) succeeded, we wouldn't do the second chdir().
While at it, simplify the logging logic: if chdir() fails in this core function,
just always log is as error including the unix token.

session->compat->vuid is set to session->global->session_wire_id after a
successful session setup, so both variables will always carry the same value. Cf
the next commit which removes vuid from user_struct.

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

Now all client enumerations use fsp file handles we will
aleady close them in file_close_conn() above.
The only user of dptr_closecnum() is for the strange old OS/2
semantics, so I can't get rid of it until SMB1 is removed.

I guess we better setup conn->case_sensitive before doing the
vfs_ChDir() calls, so we have a consistent result everytime.
Otherwise vfs_Chdir() would get conn->case_sensitive from
last request.
