regtools: completely rework qeditor, improve soc desc library and tools

The graphical editor can now display and editor description files.
The library has been improved to provide more useful function.
The XML format has been slightly changed: only one soc is allowed per file
(this is was already de facto the case since <soc> was the root tag).
Also introduce a DTD to validate the files.
