00477: Raise an error when importing stdlib modules compiled for a di…

…fferent Python version

This is a downstream workaround "implementing" python#137212 -
the mechanism for the check exists in Python 3.15+, where it needs to be
added to the standard library modules.
In Fedora, we need it also in previous Python versions, as we experience
segmentation fault when importing stdlib modules after update while
Python is running.

_curses, _tkinter, _tracemalloc and readline are not calling PyModuleDef_Init,
which is modified with this patch, hence they need a
direct call to the check function.

pythongh-153030: Fix quadratic complexity in incremental parsing in HTMLParser (pythonGH-153031) (pythonGH-153039)

When an unterminated construct (e.g. a tag or comment) spanned many
feed() calls, rescanning the growing buffer and concatenating new data
onto it were both quadratic.  New data is now accumulated in a list and
only joined and parsed once enough has piled up.

00489: Use BIO_eof to detect EOF for SSL_FILETYPE_ASN1

In PEM, we need to parse until error and then suppress `PEM_R_NO_START_LINE`, because PEM allows arbitrary leading and trailing data. DER, however, does not. Parsing until error and suppressing `ASN1_R_HEADER_TOO_LONG` doesn't quite work because that error also covers some cases that should be rejected.

Instead, check `BIO_eof` early and stop the loop that way.

This fixes python#151504 and adds compatibility with OpenSSL 3.5.7+
