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 Storable extension brings persistency to your data.
+
+ You may recursively store to disk any data structure, no matter
+ how complex and circular it is, provided it contains only SCALAR,
+ ARRAY, HASH (possibly tied) and references (possibly blessed) to
+ those items.
+
+ At a later stage, or in another program, you may retrieve data from
+ the stored file and recreate the same hiearchy in memory. If you
+ had blessed references, the retrieved references are blessed into
+ the same package, so you must make sure you have access to the same
+ perl class as the one used to create the relevant objects.
+
+ There is also a dclone() routine which performs an optimized
+ mirroring of any data structure, preserving its topology.
+
+ Objects (blessed references) may also redefine the way storage and
+ retrieval is performed, and/or what deep cloning should do on those
+ objects."
