1f6d8611a3 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.

dc1961cb15 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.

9444dfc991 Simplify pause handling
Gets rid of a race where unpause+pause fired in a quick succession would

07401e5829 Implement runtime monitor (un)registration
Unregistration is a hack and we shoould either make the subsystems into
an entry (if monitor allows subentry generation) or implement subsystem
unregistration in back-monitor.
