...
epoch_append should be called at the point the object is not reachable
anymore, otherwise a thread from a "future" might still access it post
reclamation.

the ground so we can process modify operations on individual entries.

Implement read throttling when writes backlog
...
Reject operations in such a case with LDAP_BUSY. If read_event feature
is on, just stop reading from the connection. However this could still
result in deadlocks in reasonable situations. Need to figure out better
ways to make it safe and still protect ourselves.

Epoch based memory reclamation
...
Similar to the algorithm presented in
https://www.cl.cam.ac.uk/techreports/UCAM-CL-TR-579.pdf
Not completely lock-free at the moment. Also the problems with epoch
based memory reclamation are still present - a thread actively observing
an epoch getting stuck will prevent LloadConnections and LloadOperations
being freed, potentially running out of memory.

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.
