As per https://peps.python.org/pep-0394/, the python binary can be one
of the following options:
- Python 2
- Python 3
- Not exist
All of the scripts in libxml2 use 'python', which may not exist.
As Python 2 reached EOL on the 1st January 2020, it's safe to move the
scripts to use python3 explicitly.
Commit 62150ed2 introduced a small regression in the error messages for
mismatched tags. This typically only affected messages after the first
mismatch, but with custom SAX handlers all line numbers would be off.
This also fixes line numbers in the SAX push parser which were never
handled correctly.
* parser.c: fixing #109227 providing more context in case of
start/end tag mismatch
* python/tests/ctxterror.py python/tests/readererr.py: update the
tests accordingly

* xmlreader.c python/drv_libxml2.py python/generator.py
python/libxml.c python/libxml.py python/libxml_wrap.h
python/types.c: patch from Stphane Bidoul for better per
context error message APIs
* python/tests/ctxterror.py python/tests/readererr.py:
update of the tests
Daniel
* python/generator.py python/libxml.c python/libxml.py
python/libxml_wrap.h python/types.c: applied and fixed a patch
from Stephane Bibould to provide per parser error handlers at the
Python level.
* python/tests/Makefile.am python/tests/ctxterror.py: added a
regression test for it.
