[ssh_x509] please split up the x509 patch

[ssh_x509 at roumenpetrov.info]

the x509 patch has picked up a number of changes unrelated to x509.
some quick, but certainly not complete, examples:
 - openssl configure flag deleted
 - ssh1 configure flag renamed
 - tcp-wrapper support re-added (after upstream dropped it)

if you want to make changes to support more stuff, that's fine, but
please release a "core" or "minimal" x509 patchset that *only* adds
x509 features.

we've been including x509 in Gentoo, but it's been painful, and it's
only getting worse.  our choices at this point are either:
 - drop it completely and make users figure things out
 - scrub/modify every x509 patch by hand, possibly screwing it up

both of those options suck.
