Upgrade cypari2 to 2.1.3

[kliem]

This is needed for python 3.11 support (#33842) and to make cypari compatible with current pari version

https://groups.google.com/g/sage-devel/c/jqmr6bDjDrk/m/XE2GlB_GBgAJ

Necessary follow ups:

• make cypari thread safe: see cypari2 #116
• remove optional build time dependency of cysignals on pari: see cypari2 #130

Depends on #33864

Is there any reason you are using snapshots from your fork of cypari2? Or is it just for testing and development?

Just for testing and development. My own GitHub account is lots faster with the GitHub actions than sagemath. Also I use this trac ticket for cysignal's CI. Once cypari and possibly cysignal are ready, we switch back to the official sources.

Sorry about that. I messed up with the tags. I'm rather confident the fix is working, it's just that the fix is not contained in the tag I created.

The new commit contains the recent changes.

The test release contains basically the following:

• Python 3.10 compatibility cypari2#103 (requires cython 0.29.20, which videlec does not like: Python 3.10 compatibility cypari2#103 (comment);

  an alternative approach without raised cython requirement could be add test for python 3.11 cypari2#115)

• provide PARI_SIGINT_block/pending address for cysignals cypari2#109 (videlec doesn't like this approach much and rather wants cypari2 to push to some signal handling stack of cysignals)

• a PariThreadPool to handle multithreading via Python cypari2#116 (doesn't work for python 3.6 yet).
