Fix issue #3938:

Assertion when checking address length in pj_ioqueue_sendto in ioqueue_common_abs.c of an IPv6 address. Looks like the PJ_ASSERT_RETURN(addrlen <= (int)sizeof(pj_sockaddr_in), PJ_EBUG) is old code that has not been updated to account for IPv6 addresses.

Thanks to @rickdialpad for the detailed report and the proposed patch.

PS: I don't think verifying the address family is necessary here as the check seems to concern about the storage capacity only. Btw, also updated the storage type (write_operation.rmt_addr) to pj_sockaddr.

CI failed, but doesn't seem related.

PJMEDIA_SRTP_HAS_DTLS set to 1 in config_site_test.h, while configure cannot detect OpenSSL, so the error is quite as expected.

Not sure why other previous CI sessions didn't fail here, perhaps OpenSSL were available most of the time (not always)?

Automated Pull Request (#86)

* Add missing openssl SECLEVEL=0 support (pjsip#3890)

Previous SECLEVEL support allowed for levels 1-5.
However, openssl defines levels 0-5. [1]

Recent openssl versions (3.0+) have moved previous
popular ciphers/key lengths (i.e. RSA1024withSHA1)
into level 0, so it is now a reasonable choice to use.

Add support for level 0.
