Get rid of lanplus-specific yet very generic in nature
lanplus_swap() function that unconditionally swaps bytes
in an arbitrary byte array. Move it to helper module and
add two conditionally working interfaces to it:
- array_ntoh() for network (BE) to host conversion, and
- array_letoh() for ipmi (LE) to host conversion.
The added functions will only perform byte swapping if
the target architecture differs in endianness from the
data source. array_ntoh() will only do swap on LE machines,
while array_letoh() will only do it on BE ones.
These functions are introduced for future use in other
places of ipmitool.
