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...

+ The popt library exists essentially for parsing command line options.
+ Some specific advantages of popt are no global variables (allowing
+ multiple passes in parsing argv), parsing an arbitrary array of
+ argv-style elements (allowing parsing of command-line-strings from any
+ source), a standard method of option aliasing, ability to exec external
+ option filters, and automatic generation of help and usage messages."
