[Bug 2055304] [NEW] openssl 3.0.2 backport IgnoreUnexpectedEOF ssl config option from 3.2

[Hanno Zysik]

Public bug reported:

I get "Closing connection 0 curl: (35) error:0A000126:SSL
routines::unexpected eof while reading" accessing some web servers.
AFAIS "SSL_OP_IGNORE_UNEXPECTED_EOF" can help here. With 3.2[0] it can
be configured in openssl.cnf, whereas 3.0[1] cannot. Would you mind to
backport the mini patch[2] to be configured with 3.0, too?

Example:
$ tail -n 3 /etc/ssl/openssl.cnf 
[system_default_sect]
CipherString = DEFAULT:@SECLEVEL=2
Options = IgnoreUnexpectedEOF
