Absolutely no discussion about the fact to have libproxy as an optional
component only.

I'll send my first patch version out these days for review. I'm sure there will
be some comments to follow up on.

The implementation so far is:
Configure supports --disable-libproxy and --enable-libproxy[={yes|no|auto}]
Default behavior for configure is to autodetect libproxy and use it if found.

The proxy settings are first read from .wgetrc if available; only if not
specifically configured for wget the request is handed over to libproxy.

The same counts for --no-proxy parameter: if specified, libproxy is not called
and direct connection is initiated.

I introduced no new dependency on pkg-config, as it's not used so far and it
would be impossible to 'autodetect' libproxy properly (configure would abort if
pkg-config can't be found. The check could only be avoided if --enable-libproxy
or --disable-libproxy would be required to be passed to configure; thus no
autodetection).

IF you have already any comments on the implementation specification above,
please let me know. I'll be eager to fix any outstandings as quick as possible.

Best regards,
Dominique
