Import OCSP documentation from OpenSSL, leaving out some stuff

that we don't have, fixing some bugs and tweaking some parts for
readability.

P.S.
Why did some people write a HTTP client implementation and then
decide that the best place to publish it might be a crypto(3)
library?  Oh never mind, to go easy on my sanity, i should probably
stop asking such questions and just document what i find.
