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...

+long_desc="
+ Python is an interpreted, interactive, object-oriented programming language
+ that combines remarkable power with very clear syntax. For an introduction
+ to programming in Python you are referred to the Python Tutorial. The Python
+ Library Reference documents built-in and standard types, constants, functions
+ and modules. Finally, the Python Reference Manual describes the syntax and
+ and semantics of the core language in (perhaps too) much detail.
+
+ Python's basic power can be extended with your own modules written in C or
+ C++. On most systems such modules may be dynamically loaded. Python is also
+ adaptable as an extension language for existing applications."
