[h323implementers] PTLib 2.10.9.6 released

Dear community,

I have just bundeled up the changes and bug fixes of the past 2 years and released PTLib 2.10.9.6.

Most notable in this release is working IPv6 on *BSD, macOSX and Solaris as well as support for newer compilers and many small platform fixes.

- IPv6 support fixed for *BSD, macOSX and Solaris - support for newer compiler, eg. gcc 13 and VS2022 - support for C++-17 - support for Win64 builds - support AIX as platform - small OpenBSD fixes - other small fixes
