Nothing productive on the upstream mailinglist (or rather disturbing,
they say that ABI can change in backward incompatible way even in minor
versions and you're always expected to recompile), BUT thanks to Stepan
Golosunov and Tzafrir in Bug#828240 there now seems to be a way to build
Asterisk 13.12.1 against OpenSSL 1.1.0. 

I have tested that build (built against pjproject 2.5.5~dfsg-2 in sid)
and it does not crash for me.

It will probably take a few more days to fully test this (and import a
few other crash fixes for pjproject as well for good measure), but now
the future looks a bit less dark than before. I will probably disable
the pjsip asserts as well, following upstream recommendation.
