Modify the dconfig.h header file so that libdecnumber code integrates QEMU
configuration. Specifically:
- the WORDS_BIGENDIAN preprocessor macro is used in libdecnumber code to
determines endianness. It is derived from the existing QEMU macro
HOST_WORDS_BIGENDIAN which is defined in config-host.h.
- the DECPUN macro determines the number of decimal digits (aka declets) per
unit (byte). This is 3 for PowerPC DFP.

Add files from the libdecnumber decimal floating point library to QEMU. The libdecnumber
library was originally part of GCC and contains code that is useful in emulating the PowerPC
decimal floating point (DFP) instructions. This particular copy of the source comes from
GCC 4.3 and is licensed at GPLv2+.
