[Samba] smb 3 posix extension support (minimum version for cifs.ko and smbd)

[Steve French]

For the server code (and samba tools like smbclient) it is not merged
yet - but can be tried by using
https://git.samba.org/?p=jra/samba/.git;a=shortlog;h=refs/heads/master-smb2

The kernel code is partially merged, minimum version to experiment
with the POSIX extensions is kernel version 5.1 but the ability to
query POSIX information (stat, query info) is not in the upstream
kernel client yet (since we didn't want to merge that if there was a
good chance it could change due to testing we are doing with Jeremy's
server code).  Target for those remaining features is kernel version
5.4, although some improvements (querying symlinks for example) will
be in kernel version 5.3.
