Move UINT32_LE macros to common.h

32-bit integer manipulation macros (little edian):
GET_UINT32_LE and PUT_UINT32_LE appear in several
files in library/.
Removes duplicate code and save vertical
space the macro has been moved to common.h.
Improves maintainability.

Also provided brief comment in common.h for
BYTES_TO_U32_LE. comment/documentation will
probably need to be edited further for all
recent additions to library/common.h
