olpc-utils: hwinfo and reading mfg-data

[Martin Langhoff]

Hi Paul,

I reworked your olpc-hwinfo slightly, refactored all the utilities
reading /ofw . See
http://dev.laptop.org/git/projects/olpc-utils/commit/

My only concern is that it can't tell you whether ak/wp/ww tags
_exist_. It can read values, but empty tags return the same as a
missing tag. You may also note that the shell functions don't add a
newline.

Daniel,

two new files in the build. Might need frobbing the fedpkg spec.

cheers,
