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="
+ The libffi library provides a portable, high level programming
+ interface to various calling conventions. This allows a programmer to
+ call any function specified by a call interface description at run-time.
+
+ Some programs may not know at the time of compilation what arguments
+ are to be passed to a function. For instance, an interpreter may be
+ told at run-time about the number and types of arguments used to call
+ a given function. Libffi can be used in such programs to provide a
+ bridge from the interpreter program to compiled code.
+
+ Ffi stands for Foreign Function Interface. A foreign function
+ interface is the popular name for the interface that allows code
+ written in one language to call code written in another language.
+ The libffi library really only provides the lowest, machine dependent
+ layer of a fully featured foreign function interface.  A layer must
+ exist above libffi that handles type conversions for values passed
+ between the two languages."
