PoorMan: Default to UTF-8 character set.

Ideally we would default to no character set, but
libhttpd does not seem to support that.

Fixes #18424.

PoorMan: Add dual-stack IPv6 support

This change adds dual-stack IPv6 support to the PoorMan web server,
which will listen on all available IPv4 and IPv6 addresses and
respond to both.

This change also does some necessary plumbing to support the
output of nicely-formatted IPv6 addresses for request logging.

Fix client hang when HEAD request is sent to PoorMan

If a HEAD request was sent to PoorMan, for example from curl
("curl --HEAD http://x.x.x.x") then the client would hang due to the connection
never being closed.

In PoorManServer::_Worker, after httpd_start_request() is called, a null
file_address is used to detect when libhttpd has already sent a directory
listing. In this situation, PoorMan assumes libhttpd already fully handled the
request. However httpd_start_request() didn't properly set this flag for HEAD
requests. In the if block for a null file_address, the file descriptor was
incorrectly invalidated, which prevented the connection from closing. Fixing
this revealed two more bugs. The first is libhttpd was not actually sending
the http headers for HEAD directory listing requests. The second is
PoorManServer would increment its hit count for HEAD directory listing
requests. This change also refactors file_address to a more sensible name and
type that reflects its use.

Patch by Ma Jie: Basically - make Poorman (the webserver) work. Libhttpd from
Jef Poskanzer is providing the backend, but had to be adopted in some ways.
Other issues in Poorman have been resolved.

When testing the license integration, I stumbled over some AboutSystem bugs,
basically clicking licenses would not open them. I fixed those in this patch,
sorry for mixing that up.

Note to Ma Jie: I changed the encoding of the libhttpd files to UTF-8!
(This affects only the (C) glyph.) Thanks a lot for your awesome work on
Poorman, it's really appreciated!
