6c21c51c48 - (djm) autoconf hacking: 
- We don't support --without-zlib currently, so don't allow it.
   - Rework cryptographic random number support detection. We now detect
     whether OpenSSL seeds itself. If it does, then we don't bother with
     the ssh-rand-helper program. You can force the use of ssh-rand-helper
     using the --with-rand-helper configure argument
   - Simplify and clean up ssh-rand-helper configuration

62116dcc0a - (djm) Ignore fix & patchlevel in OpenSSL version check. Patch from 
solar@openwall.com
 - (djm) Rework entropy code. If the OpenSSL PRNG is has not been
   internally seeded, execute a subprogram "ssh-rand-helper" to obtain
   some entropy for us. Rewrite the old in-process entropy collecter as
   an example ssh-rand-helper.
 - (djm) Always perform ssh_prng_cmds path lookups in configure, even if
   we don't end up using ssh_prng_cmds (so we always get a valid file)

60bc517356 - (djm) Seed PRNG at startup, rather than waiting for arc4random calls to 
do it implicitly.

d0ccb989c2 - Allow PRNGd entropy collection from localhost TCP socket. Replace 
"--with-egd-pool" configure option with "--with-prngd-socket" and
   "--with-prngd-port" options. Debugged and improved by Lutz Jaenicke

226cfa0378 Hopefully things did not get mixed around too much. It compiles under
