[linux-cifs-client] legacy mounts

[Steven French]

Mounts to legacy servers (LANMAN level such as OS/2 and pre-Windows ME) 
now work.  I have done simple testing against OS/2 (HPFS386 server) and 
most key operations work (file times are not translated yet).

To mount to older lanman servers requires:
        very current cifs code (only in cifs-2.6 tree on kernel.org and 
possibly in -mm tree)
        building with the configure option enabled for allowing weak 
security
        "echo 2 > /proc/fs/cifs/Experimental"     (to turn on new session 
setup code)
        "echo 0x37037 > /proc/fs/cifs/SecurityFlags"  (to allow weak 
security at runtime)
        specifying the nebiosname of the server e.g. "mount -t cifs 
//server/share /mnt -o servern=MYSRVNAME"

I will be cleaning up the mount option processing so the sec flag passed 
on mount can override the default security flags when root, and fixing the 
mount helper so the "servern" mount parm will not usually have to be 
specified.   I need to do a backport of the last dozen patches or so to 
the cifs-for-older-kernels tree on kernel.org and include the corrections 
minor version number checks which various of you all have submitted based 
on your buildtesting on various distros/kernel levels - I also need to 
update the corresponding tar.gz for those who don't use git/cogito
