- Also removes all references to boost/cstdint.hpp and replaces it with
stdint.h (The 'correct' replacement would be <cstdint>, but not all of our
compilers support that).
- Use ULL and LL etc. so compiler doesn't need to decide constant's types
- define the empty 'while' loop to include {} to make older compilers happy
- Use explicit type names for BOOST_CHECK_EQUAL
Our VRT routines have the option to switch, on the fly, between
VRLP and CHDR. This adds new CHDR-specific (un-)packers, which
can only work with CHDR.
