(CVE-2023-52425, bsc#1219559) by adding five new methods:
xml.etree.ElementTree.XMLParser.flush()
xml.etree.ElementTree.XMLPullParser.flush()
xml.parsers.expat.xmlparser.GetReparseDeferralEnabled()
xml.parsers.expat.xmlparser.SetReparseDeferralEnabled()

- gh-81194: Fix a crash in socket.if_indextoname() with
specific value (UINT_MAX). Fix an integer overflow in
socket.if_indextoname() on 64-bit non-Windows platforms.
- gh-109858: Protect zipfile from “quoted-overlap”
zipbomb. It now raises BadZipFile when try to read an
entry that overlaps with other entry or central directory
(CVE-2024-0450, bsc#1221854).

return SSL_ERROR_SYSCALL instead of SSL_ERROR_SSL
when a certification verification has failed, but
the error parameters will still contain ERR_LIB_SSL
and SSL_R_CERTIFICATE_VERIFY_FAILED. We are now
detecting this situation and raising the appropiate
ssl.SSLCertVerificationError. Patch by Pablo Galindo
