djm@openbsd.org 0bc6b4c8f0 upstream: fix some integer overflows in sieve_large() that show up when 
trying to generate modp groups > 16k bits. Reported via GHPR#306 by Bertram
Felgenhauer, but fixed in a different way. feedback/ok tb@

djm@openbsd.org fd1a96490c upstream: remove most uses of BN_CTX 
We weren't following the rules re BN_CTX_start/BN_CTX_end and the places
we were using it didn't benefit from its use anyway. ok dtucker@

Damien Miller 72ef7c148c support --without-openssl at configure time 
Disables and removes dependency on OpenSSL. Many features don't
work and the set of crypto options is greatly restricted. This
will only work on system with native arc4random or /dev/urandom.

Considered highly experimental for now.
