janwas a34b759720 . split up lib.h/.cpp, include the remnants from PCH, remove (pretty much universal) include of it.
. timer, config: fix definition of ALLOW_RDTSC
. add movsx_be64 (for whirlpool), revise implementation, move to
byte_order, add test
. MAX -> std::max, remove those macros
. add timestamp to system_info as requested by philip

This was SVN commit r5050.
