- dce/rpc code

- removed debug info in struni2 and unistr2 (security risk)

- rpc_pipe function was getting pointer to data then calling realloc *dur*

- password check function, the start of "credential checking",
  user, wks, domain, pass as the credentials (not just user,pass which
  is incorrect in a domain context)

- cli_write needs to return ssize_t not size_t, because total can be -1
  if the write fails.

- fixed signed / unsigned warnings (how come i don't get those any more
  when i compile with gcc???)

- nt password change added in smbd.  yes, jeremy, i verified that the
  SMBtrans2 version still works.
