SMB1 protocol supports non-UNICODE (8-bit OEM character set) and
UNICODE (UTF-16) modes. Linux SMB1 client implements both of them but
there are few bugs in processing non-UNICODE mode.

This patch series add a new mount option -o nounicode to disable UNICODE
mode and force usage of non-UNICODE (8-bit OEM character set) mode. This
allows to test non-UNICODE code path against modern/recent SMB servers
which implements and prefer UNICODE mode.

And this patch series fixes SMB1 session setup and reading symlinks when
UNICODE mode is not active.

Tested against Windows Server 2022 SMB1 server and older Samba SMB1
server.
