This is done in gnutls.c (using a host name passed through
`gnutls-negotiate' from gnutls.el) now. The verification can be turned
off.

I am not sure this is useful as part of the GnuTLS connection mechanism
because pausing external network-level C functions to interact with the
user can cause some serious bugs. It seemed like a good approach but
after working with the GnuTLS code I'm pretty sure it will cause
problems long-term.
It's probably cleaner to save every invalid certificate in a list and
give the user a UI to choose which certificates they wish to accept,
perhaps linking to the last validation failure and whatever else will
help the user identify which certificates he wants to accept (maybe a
hash ID of the certificate in the messages buffer).
Any opinions?
Ted
