Plain known-host entries are currently compared as text, so equivalent
expanded and compressed IPv6 literals do not match.
This change keeps the existing exact-string fast path and compares two
valid plain IPv6 literals by their 128-bit address. It also supports
bracketed IPv6 host-and-port entries while requiring the port suffix to
match exactly.
No DNS lookup is performed. Hostname matching and the CUSTOM and hashed
known-host paths remain unchanged.

Fixes#1398Closes#2568
Checker script and wordlist comes from curl.
Also:
- checksrc.pl: sync up with curl.
- unfold an IETF URL.
- update all IETF URLs where missing.
Closes#1959
To render in Git webviews as-is, to make it easier to edit, verify,
and to sync up with curl.
- add options to not build the `.3` man pages:
- autotools: `--disable-docs`
- cmake: `LIBSSH2_BUILD_DOCS=OFF`
- building `.3` man pages requires Perl after this patch.
- drop `mansyntax` and the shell / `grep` / GNU `man` tool requirements with it.
- scripts and most logic were copied from curl.
- add `cd2nroff` from curl, with edits to relax curl-specific checks.
- used `nroff2cd` (from curl) to convert from `.3` to `.md`. Then
manually fixed copyrights, inline function references and a couple
of other things.
