37daeb220e spnego: ignore server mech_types list
We should not use the mech list sent by the server in the last
'negotiate' packet in CIFS protocol, as it is not protected and
may be subject to downgrade attacks.

f988756599 auth/gensec: fix AES schannel seal and unseal
Workaround bug present in gnutls 3.6.8:

gnutls_cipher_decrypt() uses an optimization
internally that breaks decryption when processing
buffers with their length not being a multiple
of the blocksize.

a5e8a5e05b auth/pycreds/encrypt_netr_crypt_password: don't pretend arg is optional
The "|O" signature is saying the password argument is optional, which
makes no sense in terms of the funxtion and immediately leads to a
TypeError (or until last commit, segfault). Removing the "|" leaves it
with a TypeError, but it is better worded and faster.
