New function doesn't need a TWRP argument and returns NT_STATUS_OK
on successful redirect, not NT_STATUS_PATH_NOT_COVERED.
Comment out the old dfs_path_lookup().
There are now no more users of unix_convert().

If the terminal component was an MSDFS link, openat_pathref_fsp_case_insensitive() will
return NT_STATUS_OBJECT_NAME_NOT_FOUND with a VALID_STAT of a symlink.
If this is the case, check if we actually found a terminal MS-DFS link
at the end of the pathname and return NT_STATUS_PATH_NOT_COVERED.

This is what we will use to replace dfs_redirect() in the filename
conversion code. Keep as a wrapper for now as we might want to
add some error checking around the 'hostname' and 'service'
returns.

(cherry picked from commit 245d07ab84852b829c029496618e56782d070e83)
#ifdef'ed out as static and not yet used.
We can't just call check_path_syntax() on these as
they are of the form hostname\share[\extrapath]
(where [\extrapath] is optional).
hostname here can be an IPv6 ':' separated address,
which check_path_syntax() fails on due to the streamname
processing.
NB. This also has to cope with out existing (broken)
libsmbclient libraries that sometimes set the DFS
flag and then send a local pathname. Cope by just
calling the normal check_path_syntax() on the
whole pathname in that case.

(cherry picked from commit bcba5502282eb6dcc346d7c63aa3218cda2f9bb0)
The Linux kernel SMB1 client has a bug - it sends
DFS pathnames as:
\\server\share\path
instead of:
\server\share\path
Causing us to mis-parse server,share,remaining_path here
and jump into 'goto local_path' at 'share\path' instead
of 'path'.
This doesn't cause an error as the limits on share names
are similar to those on pathnames.
parse_dfs_path() which we call before filename parsing
copes with this by calling trim_char on the leading '\'
characters before processing.
Do the same here so logging of pathnames looks better.
How did I find this ? Lots and lots of manual
testing with the Linux kernel client to make
sure all the recent changes haven't broken Linux
SMB1/2/3 DFS :-).

(cherry picked from commit 2818fd6910201fd4a18b921933a0b7392a0a8995)
This test calls SMB2_Echo in a loop per connection.
For 4 connections with 2 parallel loops use this:
time smbtorture //127.0.0.1/m -Uroot%test smb2.bench.echo \
--option="torture:timelimit=600" \
--option="torture:nprocs=1" \
--option="torture:qdepth=2"
Sometimes the bottleneck is the smbtorture process.
In order to bring the smbd process to 100% cpu, you can use
'--option="libsmb:client_guid=6112f7d3-9528-4a2a-8861-0ca129aae6c4"'
and run multiple instances of the test at the same time,
which both talk to the same smbd process.
This is a very useful test to show how many requests are possible
at the raw SMB2 layer.

This is inspired by 0d4cb5a641e1fea2d369bdc66470a580321366c2,
which avoids SMB_VFS_FGET_NT_ACL() for the root user again.
Opens with just FILE_READ_ATTRIBUTES are very common, so it's worth
optimizing for it.
