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...

+ D-BUS is a message bus, used for sending messages between applications.
+ Conceptually, it fits somewhere in between raw sockets and CORBA in terms
+ of complexity.
+
+ D-BUS supports broadcast messages, asynchronous messages (thus decreasing
+ latency), authentication, and more.  It is designed to be low-overhead;
+ messages are sent using a binary protocol, not using XML.  D-BUS also
+ supports a method call mapping for its messages, but it is not required;
+ this makes using the system quite simple."
