doesn't actually leave us in the requested sec context between
requests yet, but it does prevent us from doing the samdb lookup on
every packet.
This change speeds up the BASE-MANGLE test against Samba4 with 5000
operations from 61 seconds to 16 seconds. For reference, Samba3 takes
27 seconds for the same test (the string and filename handling in
Samba4 is much more efficient than Samba3)

"unixName" to be more ldap traditional
- register the unixuid module as all 3 ntvfs backend types, as it doesn't care what type of backend
it filters

conjunction with the posix backend this gives us a way to correctly
setup the unix security context in Samba4.
I chose the following method to determine the unix uid's and gid's to
use given the list of SIDs from the login process
- look for a "UnixID" field in the sam record. If present, then use it
(check if the record is of the right type as well)
- if UnixID is not present, then look for the "UnixName" sam
field. If it is present then use getpwnam() or getgrnam() to find
the unix id.
- if UnixID and UnixName are not present, then look for a unix
account of the right type called by the same name as the sAMAccountName field.
- if none of the above work then fail the operation with NT_STATUS_ACCESS_DENIED
obviously these steps only work well with a local SAM. It will need to
be more sophisticated in future.
I did not put any cache in place at all. That will need to be added
for decent performance.
