r8627: fixed a big memory leak in the spnego gensec code in session
setup. Andrew, please check over this.
What happens is this:
- run the BASE-SECLEAK test
- with each failed session setup using spnego a gensec ctx is leaked into the smb_conn structure
- after the client disconnects these are finally cleaned up as they
are all children of the connection structure
- the cleanup of the millions of memory objects takes long enough
that the next operation in test_posix.sh sometimes fails with a timeout
Andrew, can you also look at the talloc_reference() on line 332 of
sesssetup.c ? I suspect it isn't needed (I don't think it does any
actual harm though)
