Major infrastructure changes, part 2.
* Moved helpers, common and triggers dirs into xbps-src, where
they belong.
* Renamed the templates dir to srcpkgs, it was so redundant before.
* Make it possible to add subpkgs with no restriction in names, for
example udev now has a subpkgs called "libgudev". Previously
subpkgs were named "${sourcepkg}-${pkgname}".
* xbps-src: changed to look for template files in current directory.
That means that most arguments from the targets have been removed.
* xbps-src: added a reinstall target, to remove + install.
* xbps-src: do not overwrite binpkgs by default, skip them.
And more that I forgot because it's a mega-commit that I've been
working for some days already...
