- bump to 2.13
- new option "--disable-libsrtp" now available so we can get rid of
dependency on libsrtp2 (asterisk's SRTP support doesn't depend on pjproject)
- new option "--disable-upnp"
- 0007-execinfo.patch not required anymore, pjproject now checks for
__GLIBC__
- sync patches with asterisk 20.3.0
