cmdmon: define 64-bit integer

Browse Source 
Add a structure for 64-bit integers without requiring 64-bit alignment
to be usable in CMD_Reply without struct packing.

Add utility functions for conversion to/from network order. Avoid using
be64toh() and htobe64() as they don't seem to be available on all
supported systems.
