More LibreSSL patches

Browse Source 
As dcooper16 noted in #834 there are checks which test for openssl versions
but don't take LibreSSL in account. This adds checks to it for several
LibreSSL versions (>=2.1.x) which are known to support ``determine_trust()``
and it HAS_DH_BITS.

Moreover engine check has been improved. Older LibreSSL versions (2.1 specifically)
had different error messages, so the previous checks failed. There's also
a CMD_LINE flag now where one can switch the engine support off: NO_ENGINE .

run_renogo from #834 is still an open issue.
