Since we don't use networking directly but rather via libuv, these
configure options were no-op. Remove the configure checks for epoll
(Linux), kqueue (BSDs) and /dev/poll (Solaris).

Utilize developers' muscle memory to incentivize using the pytest runner
instead of the legacy one. The script also serves as basic examples of
how to run the pyest command to achieve the same results as the legacy
runner.
Invoking pytest directly should be the end goal, since it offers many
potentially useful options (refer to pytest --help).

(also manually added a additional run.sh -> legacy.run.sh renames)
We don't need them in the repo, it's sufficient if we pregenerate them
while preparing the tarball. That way we don't have overhead while
modifying them but they are still available for installations without
Sphinx.
I assume that this will make rebases and cherry-picks across branches
easier, with less trial and error churn required in the CI.
It's implemented in the way that we build the manpages only when we
either have pregenerated pages available at the configure time or
sphinx-build is installed and working.

The implementation of UDP recvmmsg in libuv 1.35 and 1.36 is
incomplete and could cause assertion failure under certain
circumstances.
Modify the configure and runtime checks to report a fatal error when
trying to compile or run with the affected versions.

The --enable-dnsrps-dl switch for ./configure enables preparing a
DNSRPS-enabled build of BIND 9 that is not directly linked against a
DNSRPS provider library (dlopen() at runtime is used instead). Employ
this switch to test DNSRPS-enabled builds in the pairwise testing job in
GitLab CI.

Prefer the pthread_barrier implementation on platforms where it is
available over uv_barrier implementation. This also solves the problem
with thread sanitizer builds on macOS that doesn't have pthread barrier.

The NetBSD system allocator is in fact based on the jemalloc, but it
doesn't export the extended interface, so we can't use that. Remove
the jemalloc enforcement for the NetBSD.
(cherry picked from commit feea72414b)
When jemalloc is the system allocator (on FreeBSD and NetBSD), trying
to build --without-jemalloc caused an obscure compiler error. Instead,
complain at configure time that --without-jemalloc cannot work. (It
needs to remain an error because it is vexing when configure quietly
ignores an explicit direction.)

previously, when ISC_BUFFER_USEINLINE was defined, macros were
used to implement isc_buffer primitives (isc_buffer_init(),
isc_buffer_region(), etc). these macros were missing the DbC
assertions for those primitives, which made it possible for
coding errors to go undetected.
adding the assertions to the macros caused compiler warnings on
some platforms. therefore, this commit converts the ISC__BUFFER
macros to static inline functions instead, with assertions included,
and eliminates the non-inline implementation from buffer.c.
the --enable-buffer-useinline configure option has been removed.

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.
(cherry picked from commit 568f65cc56)
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/.

When autoconf was checking for libuv features, the LIBUV_CFLAGS was not
added to CFLAGS and LIBUV_LIBS to LIBS which resulted in false
negatives.
Use AX_SAVE_FLAGS and AX_RESTORE_FLAGS to temporarily add LIBUV_CFLAGS
and LIBUV_LIBS to their respective variables.

From the ld man page:
When creating a dynamically linked executable, using the -E option or
the --export-dynamic option causes the linker to add all symbols to
the dynamic symbol table. The dynamic symbol table is the set of
symbols which are visible from dynamic objects at run time.
This should allow the backtrace(3) to fully resolve the symbols when
creating backtrace on an assertion failure.
