* dconfig.h: New.
* decContext.c, decExcept.c, decExcept.h, decLibrary.c,
decNumber.c, decNumberLocal.h, decRound.c, dpd/decimal128.c,
dpd/decimal32.c, dpd/decimal64.c: Include dconfig.h not config.h.
* dpd/decimal128Local.h (decimal128SetSign, decimal128ClearSign,
decimal128FlipSign): Use WORDS_BIGENDIAN not
FLOAT_WORDS_BIG_ENDIAN.
* bid/host-ieee128.c: Include dconfig.h.
(__host_to_ieee_128, __ieee_to_host_128): Swap 64-bit halves of
value if WORDS_BIGENDIAN.
