Stop logging "Tried to establish rendezvous on non-OR circuit..." as
a warning. Instead, log it as a protocol warning, because there is
nothing that relay operators can do to fix it.

Fixes bug 29029; bugfix on 0.2.5.7-rc.

In theory it would be better to detect this bug in advance, but this
approach is much simpler, and therefore safer to backport.

This closes tor issue 28973.

Merge Phoul's two lists into teor's list.

Replace the 150 fallbacks originally introduced in Tor 0.3.3.1-alpha in
January 2018 (of which ~115 were still functional), with a list of
157 fallbacks (92 new, 65 existing, 85 removed) generated in
December 2018.

Closes ticket 24803.

This avoids leaking memory in case libtorrunner's child() function fails.

Apparently some freebsd compilers can't tell that 'c' will never
be used uninitialized.

Fixes bug 28413; bugfix on 0.2.9.3-alpha when we added support for
longer AES keys to this function.

Apparently, even though the manpage says it returns an int, it
can return a long instead and cause a warning.

Bug not in any released Tor.  Part of #28399

Failing to do on clients was causing TLS 1.3 negotiation to fail.
