Witold Kręcicki 54d420f391 netmgr: 
- clean up isc_nmevent structures - make generic types and just typedef to them
 - fix atomic clang warnings in astack
 - add pause/resume read for TCP
 - add sequential (not-pipelining) support for TCPDNS
 - keep peer address in the socket for TCP connections, it's constant for a socket

Evan HuntandWitold Kręcicki 22795df7e5 reattach the nmhandle to the client when running a prefetch 
this delays the destruction of the client object until after the
prefetch is finished.

also added some missing CTRACE logging in query.c, in the process of
diagnosing this error.

Evan HuntandWitold Kręcicki 6d7934d6f5 use isc_mem_get() instead of malloc() 
the advantage of this is it allows the use of memory context
accounting, but it will likely have performance consequences.

XXX: we need to find a way to do a TCPDNS send without having to allocate
and copy the region that's to be sent.

Witold Kręcicki 2324d5c569 Fix isc_nm_pause - it was counting paused workers incorrectly 2019-11-05 12:54:44 +01:00
Evan HuntandWitold Kręcicki 97c11c43b9 fix reference counting in ns_client and ns_clientmgr 
- add reference counters to manager; all client objects attach and
  detach from the manager
- ensure that when a client object is detached, if references have gone
  to zero, the associated nmhandle object is detached. this should
  trigger the freeing of both the nmhandle object and the client object
 2019-11-05 12:54:44 +01:00
Evan HuntandWitold Kręcicki c0cd4c1d92 begin cleanup of ns_client 
- as client objects are now allocated along with network manager clients
  and will be accounted for by the network manager, there's no longer a
  need to call exit_check(). its functions are now replaced by the
  nmhandle reset and put callbacks.
- there is no need to keep a 'clients' list in ns_clientmgr()
- (however, TODO, the client manager should now be reference counted)
- added some logging to show when clients are allocated, reset, or freed
- ns_client_next() has no remaining function except to log the reason
  for a failure. its name has therefore been changed to ns_client_drop().
