[COMMIT] sync up pass 3

[Eric W. Biederman]

First stab at synchronizing the questionable code.

The NLBConfig.py and getpir changes are safe simple changes.

The read_bytes.h and rom_fill_inbuf.c removes tag support from LinuxBIOS
altogether.  The code is in the baremetal toolkit so we should not need
it bloating the common code.
