Clear the callbacks when isc_nm_stoplistening() is called

Split netmgr_test into separate per-transport unit tests
The netmgr_test unit test has been subdivided into tcp_test,
tcpdns_test, tls_test, tlsdns_test, and udp_test components.
These have been updated to use the new loopmgr.
* isc_timer was rewritten using the uv_timer, and isc_timermgr_t was
completely removed; isc_timer objects are now directly created on the
isc_loop event loops.
* the isc_timer API has been simplified. the "inactive" timer type has
been removed; timers are now stopped by calling isc_timer_stop()
instead of resetting to inactive.
* isc_manager now creates a loop manager rather than a timer manager.
* modules and applications using isc_timer have been updated to use the
new API.
This commit introduces new APIs for applications and signal handling,
intended to replace isc_app for applications built on top of libisc.
* isc_app will be replaced with isc_loopmgr, which handles the
starting and stopping of applications. In isc_loopmgr, the main
thread is not blocked, but is part of the working thread set.
The loop manager will start a number of threads, each with a
uv_loop event loop running. Setup and teardown functions can be
assigned which will run when the loop starts and stops, and
jobs can be scheduled to run in the meantime. When
isc_loopmgr_shutdown() is run from any the loops, all loops
will shut down and the application can terminate.
* signal handling will now be handled with a separate isc_signal unit.
isc_loopmgr only handles SIGTERM and SIGINT for application
termination, but the application may install additional signal
handlers, such as SIGHUP as a signal to reload configuration.
* new job running primitives, isc_job and isc_async, have been added.
Both units schedule callbacks (specifying a callback function and
argument) on an event loop. The difference is that isc_job unit is
unlocked and not thread-safe, so it can be used to efficiently
run jobs in the same thread, while isc_async is thread-safe and
uses locking, so it can be used to pass jobs from one thread to
another.
* isc_tid will be used to track the thread ID in isc_loop worker
threads.

nsec3.c: Add a missing dns_db_detachnode() call

Add test case for #3486
Add two scenarios where we change the dnssec-policy from using RSASHA1
to something with NSEC3.
The first case should work, as the DS is still in hidden state and we
can basically do anything with DNSSEC.
The second case should fail, because the DS of the predecessor is
published and we can't immediately remove the predecessor DNSKEY. So
in this case we should keep the NSEC chain for a bit longer.
Add two more scenarios where we change the dnssec-policy from using
NSEC3 to something NSEC only. Both should work because there are no
restrictions on using NSEC when it comes to algorithms, but in the
cases where the DS is published we can't bluntly remove the predecessor.
Extend the nsec3 system test by also checking the DNSKEY RRset for the
expected DNSKEY records. This requires some "kasp system"-style setup
for each test (setting key properties and key states). Also move the
dnssec-verify check inside the check_nsec/check_nsec3 functions because
we will have to do that every time.

Wait with NSEC3 during a DNSSEC policy change
When doing a dnssec-policy reconfiguration from a zone with NSEC only
keys to a zone that uses NSEC3, figure out to wait with building the
NSEC3 chain.
Previously, BIND 9 would attempt to sign such a zone, but failed to
do so because the NSEC3 chain conflicted with existing DNSKEY records
in the zone that were not compatible with NSEC3.
There exists logic for detecting such a case in the functions
dnskey_sane() (in lib/dns/zone.c) and check_dnssec() (in
lib/ns/update.c). Both functions look very similar so refactor them
to use the same code and call the new function (called
dns_zone_check_dnskey_nsec3()).
Also update the dns_nsec_nseconly() function to take an additional
parameter 'diff' that, if provided, will be checked whether an
offending NSEC only DNSKEY will be deleted from the zone. If so,
this key will not be considered when checking the zone for NSEC only
DNSKEYs. This is needed to allow a transition from an NSEC zone with
NSEC only DNSKEYs to an NSEC3 zone.
Fix statistics channel multiple request processing with non-empty bodies
When the HTTP request has a body part after the HTTP headers, it is
not getting processed and is being prepended to the next request's data,
which results in an error when trying to parse it.
Improve the httpd.c:process_request() function with the following
additions:
1. Require that HTTP POST requests must have Content-Length header.
2. When Content-Length header is set, extract its value, and make sure
that it is valid and that the whole request's body is received before
processing the request.
3. Discard the request's body by consuming Content-Length worth of data
in the buffer.
