x1000-installer: Initial commit of new framework
This is a new flash installer framework for the X1000 targets.
A bunch of this code is *UNTESTED* but there is an external test
harness which allows the library to be built and tested on a PC.
Once tests are written and the bugs are ironed out this framework
will replace the existing installer code.
New features:
- Update tarballs are MD5-checksummed to guarantee integrity.
- The flash map is no longer fixed -- updates are self describing and
carry a map file which specifies the areas to update.
- Can take full or partial backups with checksums computed on the fly.
- Supports an additional verification mode which reads back data after
writing to ensure the flash contents were not silently corrupted.
