enabled have a TTL matching the value of the stale-answer-ttl setting.

5072. [bug] Add unit tests for isc_buffer_copyregion() and fix its
behavior for auto-reallocated buffers. [GL #644]
(cherry picked from commit 07050fb49a)
While isc_buffer_copyregion() calls isc_buffer_reserve() to ensure the
target buffer will have enough available space to append the contents of
the source region to it, the variables used for subsequently checking
available space are not updated accordingly after that call. This
prevents isc_buffer_copyregion() from working as expected for
auto-reallocated buffers: ISC_R_NOSPACE will be returned if enough space
is not already available in the target buffer before it is reallocated.
Fix by calling isc_buffer_used() and isc_buffer_availablelength()
directly instead of assigning their return values to local variables.
(cherry picked from commit e1f0aed034)
Add some basic checks for isc_buffer_copyregion() to ensure it behaves
as expected for both fixed-size buffers and buffers which can be
automatically reallocated. Adjust the list of headers included by
lib/isc/tests/buffer_test.c so that it matches what that test program
really uses.

If an RPZ zone is to be freed during an update, canceling the
update_quantum() event is not enough because the resources released when
an update completes also need to be accounted for. Failure to do this
results in a hang upon shutdown. Fix by copying cleanup code from the
end of update_quantum() to rpz_detach().
(cherry picked from commit 139bc2c6ab)
If another RPZ update is pending when processing the previous one nears
completion and min-update-interval is set to 0, isc_timer_reset() gets
called with 'interval' set to 0, which triggers an assertion failure.
To prevent such a scenario from causing a crash, queue the update event
directly instead of asking the timer thread to do it.

The XSL stylesheet used by the web interface does not currently include
any element which would cause a list of zones configured in each view to
be displayed, making the "Zones" section of the web interface empty
unless some zone has been configured with "zone-statistics full;" and
queried. Since this can be confusing, modify the XSL stylesheet so that
a list of zones configured in each view is displayed in the web
interface.

5051. [doc] Documentation incorrectly stated that the
"server-addresses" static-stub zone option accepts
custom port numbers. [GL #582]
(cherry picked from commit 6b1c0a8e6f)
Contrary to what the documentation states, the "server-addresses"
static-stub zone option does not accept custom port numbers. Fix the
configuration type used by the "server-addresses" option to ensure
documentation matches source code. Remove a check_zoneconf() test which
is unnecessary with this fix in place.
