[PATCH 0/6]Reorganize nvramtool code

[Patrick Georgi]

Hi, I intend to make nvramtool usable in a payload environment.
For this, the code needs to be moved around a bit so code using
FILE* interfaces (that don't exist in libpayload) doesn't prevent
the non-FILE* parts from building.
While at it, I also clean up things here and there, whose purpose
I can only assume lies in support for ancient compilers.

Some of the patches look huge but consist mainly of files that were
moved around.
