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.

A SoC descriptor is not a small object: it can be as large as ~100KiB so
it's better to avoid copying things over.

Change the XML description to unify multi dev/reg in a clean
fashion. Move the description parser to its own library. Fix
the tester and headergen tools to work with the new format and
library. Move the STMP3700/3780 descriptions to the new format
(and fixes many errors as well). Drop the hwemulgen tool
in favor on the upcoming hwstub tools revamp.
