Someday revisit various issues: Tempest parts support writing
more than one word at a time; for some target firmware it might
be necessary to save and restore flash IRQ configuration. (The
safest policy is likely to always reset after flash updates.)
Plus swap some undesirable TAB characters with SPACE.

Bugfix the read side of flash protection:
- read the right register(s)!
- handle more than 64K
- record the results in the right places
- don't display garbage.
Partially bugfix the write side:
- use 2KB lock regions instead of 1KB pages (!)
- validate input range
- don't try to _remove_ protection (it's write-once)
- #define values we'll need to commit writes.
- ... still doesn't handle pages over 64KB mark, or commit writes
And minor cleanup and fixes:
- get rid of some forward decls
- properly locate a doxygen comment
- fix some bad indentation
- remove superfluous #include
- add a new part ID (many are still missing)
- make the downloaded algorithm code be read-only

Remove the now vestigial <flash/flash.h> header from the tree,
replacing a few references with <flash/nor/core.h>

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "flash.h"
the following form should be used.
#include <flash/flash.h>
The exception is from .c files in the same directory.

Moves NOR flash drivers to 'src/flash/nor/'.
Adds 'src/flash/nor/Makefile.am'.
Builds 'libocdflashnor.la'.
