devtool: add configure-help subcommand

Browse Source 
When you need to set EXTRA_OECONF for a recipe, you need to know what
options the configure script actually supports; the configure script
however is only accessible from within a devshell and (at least in the
case of autotooled software fetched from an SCM repository) may not
actually exist until do_configure has run. Thus, provide a "devtool
configure-help" subcommand that runs the configure script for a recipe
with --help and shows you the output through a pager (e.g. less),
prefaced by a header describing the current options being specified.

There is basic support for autotools, cmake and bare configure scripts.
The cmake support is a little hacky since cmake doesn't really have a
concise help option that lists user-defined knobs (without actually
running through the configure process), however that being a design
feature of cmake there's not much I can think of to do about that at
the moment.
