autoconf: Add support for setting CURLDIR, OPENSSLDIR, EXPATDIR

Add support for --with-openssl=PATH and --without-openssl,
--with-curl=PATH and --without-curl, --with-expat=PATH and
--without-expat ./configure options, each setting or unsetting
appropriate NO_PACKAGE and if called with argument also PACKAGEDIR
(of which only CURLDIR is documented in Makefile)

All above options are supported as override to autodetection; more to
come in the same style (override to autodetection), so moved the bulk
of comments for site configuration down.

Needs review by someone well versed in autoconf and m4.
