BIND 9.17 changed exit code of skipped test to meet Automake
expectations in fa505bfb0e. BIND 9.16 was
not rewritten to Automake, but for consistency reasons, the same
SKIPPED_TEST_EXIT_CODE preprocessor macro is used (though the actual
exit code differs from the one in BIND 9.17).

cppcheck 2.2 reports the following false positive:
lib/isc/tests/quota_test.c:71:21: error: Array 'quotas[101]' accessed at index 110, which is out of bounds. [arrayIndexOutOfBounds]
isc_quota_t *quotas[110];
^
The above is not even an array access, so this report is obviously
caused by a cppcheck bug. Yet, it seems to be triggered by the presence
of the add_quota() macro, which should really be a function. Convert
the add_quota() macro to a function in order to make the code cleaner
and to prevent the above cppcheck 2.2 false positive from being
triggered.

We introduce a isc_quota_attach_cb function - if ISC_R_QUOTA is returned
at the time the function is called, then a callback will be called when
there's quota available (with quota already attached). The callbacks are
organized as a LIFO queue in the quota structure.
It's needed for TCP client quota - with old networking code we had one
single place where tcp clients quota was processed so we could resume
accepting when the we had spare slots, but it's gone with netmgr - now
we need to notify the listener/accepter that there's quota available so
that it can resume accepting.
Remove unused isc_quota_force() function.
The isc_quote_reserve and isc_quota_release were used only internally
from the quota.c and the tests. We should not expose API we are not
using.
