Allow adjusting the maximum number of cached directories per share
(defaults to 16) via mount parm "max_cached_dirs"

Commit abdb1742a3 removed code that clears ctx->username when sec=none, so attempting
to mount with '-o sec=none' now fails with -EACCES. Fix it by adding that logic to the
parsing of the 'sec' option, as well as checking if the mount is using null auth before
setting the username when parsing the 'user' option.
Fixes: abdb1742a3 ("cifs: get rid of mount options string parsing")

Handle trailing and leading separators when parsing UNC and prefix
paths in smb3_parse_devname(). Then, store the sanitised paths in
smb3_fs_context::source.
This fixes the following cases
$ mount //srv/share// /mnt/1 -o ...
$ cat /mnt/1/d0/f0
cat: /mnt/1/d0/f0: Invalid argument
The -EINVAL was returned because the client sent SMB2_CREATE "\\d0\f0"
rather than SMB2_CREATE "\d0\f0".
$ mount //srv//share /mnt/1 -o ...
mount: Invalid argument
The -EINVAL was returned correctly although the client only realised
it after sending a couple of bad requests rather than bailing out
earlier when parsing mount options.
