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...

+ Perl is a general-purpose programming language originally developed
+ for text manipulation and now used for a wide range of tasks including
+ system administration, web development, network programming, GUI
+ development, and more.  The language is intended to be practical (easy
+ to use, efficient, complete) rather than beautiful (tiny, elegant,
+ minimal).  Its major features are that it's easy to use, supports both
+ procedural and object-oriented (OO) programming, has powerful built-in
+ support for text processing, and has one of the world's most impressive
+ collections of third-party modules."
