Python since 3.12 prints warning about Py_NoSiteFlag is deprecated. It
seems that variable is not needed since Python 3.8, since it sets in
such cases directly config.site_import variable few moments later.
Move using deprecated variable to versions before that flag in config
could be used only.
This should fix warning like:
pythonmod/pythonmod.c: In function 'pythonmod_init':
pythonmod/pythonmod.c:359:7: warning: 'Py_NoSiteFlag' is deprecated [-Wdeprecated-declarations]
359 | Py_NoSiteFlag = 1;

This commit adds proper support for multiple instances of the python
module: When more than one instance is added to the module list, the
first instance loads the first script specified in the `python:`
configuration section. The second instance loads the second script,
and so on.
When there are more module instances in the module list than there are
scripts in the `python:` section, an error is raised during
initialization and unbound won't start. When more scripts than module
instances are provided, the surplus scripts are ignored.
The python module used to assign None to the per-query (qdata argument)
and per-module (mod_env variable) data stores. Hence, there was no
obvious way for python code to use these data stores.
This commit initializes both data stores with a dict instance.
PYTHON_VERSION=3.6 or with 2.7 unbound can compile and unit tests
succeed for the python module.
- pythonmod logs the python error and traceback on failure.

bypassing the cache response stage and uniquifying mesh states. Four EDNS
option lists were added to module_qstate (module_qstate.edns_opts_*) to
store EDNS options from/to front/back side.
- Added two flags to module_qstate (no_cache_lookup, no_cache_store) that
control the modules' cache interactions.
- Added code for registering inplace callback functions. The registered
functions can be called just before replying with local data or Chaos,
replying from cache, replying with SERVFAIL, replying with a resolved
query, sending a query to a nameserver. The functions can inspect the
available data and maybe change response/query related data (i.e. append
EDNS options).
- Updated Python module for the above.
- Updated Python documentation.
