fixup the version number in 9.17.0 release notes

See merge request !3145

Fix a race in isc_socket destruction.

Closes #1651

See merge request !3004

There was a very slim chance of a race between isc_socket_detach and
process_fd: isc_socket_detach decrements references to 0, and before it
calls destroy gets preempted. Second thread calls process_fd, increments
socket references temporarily to 1, and then gets preempted, first thread
then hits assertion in destroy() as the reference counter is now 1 and
not 0.

Call set resigntime and zone settimer

Closes #1627

See merge request !3137

Add more zone locks around code that touches zone timer setting
in failure modes.

zone_needdump() could potentially not call zone_settimer() so
explitly call zone_settimer() as zone->resigntime could have
gone backward.

With RRSIG records no longer being signed with the full
sig-validity-interval we need to ensure the zone->resigntime
as it may need to be set to a earlier time.

Badcache with multiple locks.

See merge request !3076

Previously badcache used one single mutex for everything, which
was causing performance issues. Use one global rwlock for the whole
hashtable and per-bucket mutexes.

Add ZLIB_LIBS to ISCLIBS

Closes #1640

See merge request !3117

When --with-zlib is passed to ./configure (or when the latter
autodetects zlib's presence), libisc uses certain zlib functions and
thus libisc's users should be linked against zlib in that case.  Adjust
Makefile variables appropriately to prevent shared build failures caused
by underlinking.

Perfwork 3/6 - Various small nits and tunables

See merge request !3067

Updating LRU requires write-locking the node, which causes contention.
Update LRU only if time difference is large enough.

Resolve "RRSIG(SOA) and re-signing."

Closes #1638

See merge request !3114

Simplify hash computation to prevent pointer being classed as tainted.

	6. byte_swapping: Performing a byte swapping operation on
	in implies that it came from an external source, and is
	therefore tainted.
