c52328f63d Clear c_auth on every bind request
For a new bind request, this is obvious, for SASL bind requests, we do
not know the final identity until we have finished handling it, make
sure it stays empty until then.

003a35c62f SASL bind support
Introduces pinned operations. When SASL bind finishes, we might still
have to maintain a link between the client an an upstream for future
bind operations if we got a SASL Bind in Progress result code. We zero
out the msgids and remember a server-unique identifer on the client and
the relevant operation that lets us retrieve that link again. This
operation is reclaimed just like anything else when connections drop.

Hopefully, this should work for LDAP TXN and VC Exop support with SASL
later as well since it allows for many-to-many links to exist.

21a22d1bf1 Refactor request parsing and sending.
We have to do most of out processing before we send the request over to
the upstream. If we don't, we might be too late and the response might
have arrived already.
