geoipbackend: Move geo2.example.com to separate file

Tests the new feature of loading zones from dir.

geoipbackend: Add zones_dir key for geoipbackend file

Allows loading zones from a directory.

Based on code by mason-chase <sid@moontius.com>

geoipbackend: Emit error and discard errorneus zones instead of failing completely

geoipbackend: Move domain loading to separate function

Simplifies next change

geoipbackend: Move global custom mapping and format to object

Simplifies following change

Change the default for building with net-snmp from `auto` to `no`

Change the default for building with net-snmp from `auto` to `no`

We have had a fair amount of issues with `net-snmp` adding unexpected
and unwanted values to both `CXXFLAGS` and `LDFLAGS`, and it was just
reported to also define `HAVE_LIBSSL` is in public header, which messes
up our own feature detection. Therefore it is likely better for everyone
to prevent net-snmp from being enabled without the user intending it.
For our own packages we explicitly enable net-snmp when supported,
and this commit also enables it in our CI for dnsdist (it was already
done for the recursor) so it should not have any impact.

TCPIOHandler: Fix a race when creating the first TLS connections

We used to get a index from OpenSSL when the first incoming or
outgoing TLS connection was created. That index is later used
to store application-related data along the TLS connection, to
be able to access it in callbacks called from inside the OpenSSL
library.
Unfortunately the atomic flag construction used was racy: if a second
connection is created while the first one is still getting the index,
it could be reading the initial value (-1) instead of the actual index,
which might prevent the callback from working properly because they
cannot retrieve the necessary data. The good news is that this should
not have a serious impact: a TLS session might not be properly resumed
while it should have been, leading to a full TLS session negotiation.
This commit fixes the race by using a full mutex and only releasing
it once the value has been computed. In order to avoid a performance
penalty, the index is now computed when a TLS connection _context_
is created, instead of a TLS connection. TLS contexts should be
reused for a large number of connections, and mostly created during
startup or in the first few seconds of the application.

The race was reported by Thread Sanitizer during the
`test_TLS.py::TestTLSFrontendLimits::testTCPConnsPerTLSFrontend`
regression test as:

rec/buildbot: Avoid running SNMP tests on the current buildbot setup

dnsdist: Split the DynBlocks regression tests

On my 8 physical CPU cores machine this brings the total time for
all regression tests to 107.60s (01:47).

Avoid running SNMP tests on the current buildbot setup

Since the change from nose to pytest, the SNMP exclusion via the environment
var NOSE_EXLUDE does no longer work.

dnsdist: Use the same UDP timeouts than usual in the 'advanced' tests

It makes sense to use a short timeout when we know this is going to
fail, but here we actually expect a response, and it seems that the
current timeout is sometimes too short when running with TSAN,
especially when we have a lot of tests running in parallel.

Format fuzzing targets

Merge pull request #13141 from rgacogne/auth-coverity-4

tools: Address more Coverity warnings

Fix building our fuzzing targets from a dist tarball

Until now all of our fuzzing targets where built with the authoritative
server, even though one of them is specific to dnsdist.
This made it easy to build all of them at once, especially for OSS-Fuzz
and CI-Fuzz, but had the unfortunate drawback of pulling several
dnsdist-specific files into the main pdns/ directory for no good
reason. It also prevented building the fuzzing targets from a dist
tarball/directory.
This commit moves the dnsdist-specific fuzzing target to the dnsdist
build process, and ensure that the standalone_fuzz_target_runner.cc
file is part of the dist tarball, making it possible to build the
fuzzing targets from the dist.
It does not move the dnsdist-specific files to the pdns/dnsdistdist/
directory yet because this would conflict with existing PRs.
