debugging changes.. temparary commit

Remove LITTLE_ENDIAN, BIG_ENDIAN #define clash and use optimized
[nh]to[nh][ls]() from BSD.

Move [nh]to[nh][ls]() into cc.h header file, allowing for
architecture-specific optimizations and to obviate the need to link
liblwip.a into libbfdmuxvm.a.

Merge from ASPLOS tree.

Initial version of public stable barrelfish repository.
