There were a number of places where the zone table should have been
locked, but wasn't, when dns_zt_apply was called.
Added a isc_rwlocktype_t type parameter to dns_zt_apply and adjusted
all calls to using it. Removed locks in callers.

Because dns_resolver_createfetch() locks the view, it was necessary
to unlock the zone in zone_refreshkeys() before calling it in order
to maintain the lock order, and relock afterward. this permitted a race
with dns_zone_synckeyzone().
This commit moves the call to dns_resolver_createfetch() into a separate
function which is called asynchronously after the zone has been
unlocked.
The keyfetch object now attaches to the zone to ensure that
it won't be shut down before the asynchronous call completes.
This necessitated refactoring dns_zone_detach() so it always runs
unlocked. For managed zones it schedules zone_shutdown() to
run asynchronously; for unmanaged zones there is no task.
Currently the 'duration_test' unit test checks only the
cfg_obj_asduration() function.
Extend the test so it checks also the reverse operation using the
cfg_print_duration() function, which is used in named-checkconf.

dohpath is specfied in draft-ietf-add-svcb-dns and has a value
of 7. It must be a relative path (start with a /), be encoded
as UTF8 and contain the variable dns ({?dns}).

This commit removes an assertion from the unit test which cannot be
guaranteed.
According to the test, exactly one client send must succeed. However,
it cannot really be guaranteed, as do not start to read data in the
accept callback on the server nor attach to the accepted handle. Thus,
we can expect the connection to be closed soon after we have returned
from the callback.
Interestingly enough, the test would pass just fine on TCP because:
a) there are fewer layers involved and thus there is less processing;
b) it is possible for the data to be sent and end up in an internal OS
socket buffer without being touched by an application's code on the
server. In such a case the client's write callback still would be
called successfully;
There is a chance for the test to succeed over TLS as well (as it
happily did before), but as the code has been changed to close unused
connections as soon as possible, the chance is far slimmer now.
What can be guaranteed is:
* cconnects == 1 (number client connections equals 1);
* saccepts == 1 (number of accepted connections equals 1).

We do this by adding callbacks for when a node is added or deleted
from the keytable. dns_keytable_add and dns_keytable_delete where
extended to take a callback. dns_keytable_deletekey does not remove
the node so it was not extended.

Affected unit tests load testdata from the srcdir. Previously, there
was a kludge that chdir()ed to the tests srcdir, but that get removed
during refactoring. Instead of introducing the kludge again, the paths
were fixed to be properly prefixed with TESTS_DIR as needed.

The libtest.la headers were installed in very weird place, in fact, we
don't need to list them in the HEADERS variable, listing them in SOURCES
is enough for autotools to figure out how to compile the convenience
library.
(cherry picked from commit 714fe2f617)
The automake was missing reference to uv_wrap.h, so it was not added to
the distribution. Add uv_wrap.h to SOURCES for both doh and netmgr unit
tests.

Move the libtest code into a 'libtest' subdirectory and make it
one of the SUBDIRS in the tests Makefile. having it at the top level
required having "." as one of the subdirs, and that caused the
unit tests to be executed twice.

The unit tests are now using a common base, which means that
lib/dns/tests/ code now has to include lib/isc/include/isc/test.h and
link with lib/isc/test.c and lib/ns/tests has to include both libisc and
libdns parts.
Instead of cross-linking code between the directories, move the
/lib/<foo>/test.c to /tests/<foo>.c and /lib/<foo>/include/<foo>test.h
to /tests/include/tests/<foo>.h and create a single libtest.la
convenience library in /tests/.
At the same time, move the /lib/<foo>/tests/ to /tests/<foo>/ (but keep
it symlinked to the old location) and adjust paths accordingly. In few
places, we are now using absolute paths instead of relative paths,
because the directory level has changed. By moving the directories
under the /tests/ directory, the test-related code is kept in a single
place and we can avoid referencing files between libns->libdns->libisc
which is unhealthy because they live in a separate Makefile-space.
In the future, the /bin/tests/ should be merged to /tests/ and symlink
kept, and the /fuzz/ directory moved to /tests/fuzz/.
