Added --with-PACKAGE[=PATH] (where PATH is prefix for PACKAGE libraries and includes) and --without-PACKAGE (--with-PACKAGE=no) support for curl, openssl, expat to configure.ac

I'm not autoconf/m4 expert: could anyone tell me how to uppercase PACKAGE name, so one could write MY_PARSE_WITH(openssl)?

How to add [=PATH] to --with-PACKAGE option description in a way which does not screw up AS_HELP_WITH calculations. I could use @<:@=PATH@:>@ which transforms to [=PATH], but AS_HELP_WITH counts number of characters in source I think.
