97288b7f10 libcli/smb: fix the credit handling on a SMB1 => SMB2 negotiate 
Our cur_credit value had 1 credit too many in the case of
an SMB1 => SMB2 upgrade. When we max out the credits the server
disconnected the connection.

1111d46cc5 libcli/smb: smb1cli_inbuf_parse_chain() and smb1cli_conn_dispatch_incoming() should use smb_len_tcp. 
They have to cope with large READX call replies that have
a length greater than smb_len_nbt() can handle.

d2d5fb1abf libcli/smb: verify decrypted SMB2 pdus correctly 
We need to make sure we got a encrypted response if we asked
for it.

If we don't get a encrypted response, we use a similar logic
as with signing to propagated wellknown errors to the higher
layer and set state->smb2.signing_skipped = true.

7a7e9b1c76 libcli/smb: fix parsing of compounded messages within a SMB2_TRANSFORM pdu 
One SMB2_TRANSFORM pdu wraps multiple SMB2 pdus.

We inject the SMB2_TRANSFORM header to each response which was wrapped
inside. This allows the next layer to verify if the SMB2 pdu was encrypted.
