pjproject_bundled: Revert pjproject 2.9 commits causing leaks

We've found a connection re-use regression in pjproject 2.9
introduced by commit
"Close #1019: Support for multiple listeners."
https://trac.pjsip.org/repos/changeset/6002
https://trac.pjsip.org/repos/ticket/1019

Normally, multiple SSL requests should reuse the same connection
if one already exists to the remote server.  When a transport
error occurs, the next request should establish a new connection
and any following requests should use that same one.  With this
patch, when a transport error occurs, every new request creates
a new connection so you can wind up with thousands of open tcp
sockets, possibly exhausting file handles, and increasing memory
usage.

Reverting pjproject commit 6002 (and related 6021) restores the
expected behavior.

We also found a memory leak in SSL processing that was introduced by
commit
"Fixed #2204: Add OpenSSL remote certificate chain info"
https://trac.pjsip.org/repos/changeset/6014
https://trac.pjsip.org/repos/ticket/2204

Apparently the remote certificate chain is continually recreated
causing the leak.

Reverting pjproject commit 6014 (and related 6022) restores the
expected behavior.

Both of these issues have been acknowledged by Teluu.
