Fix a simple bug in the decNumberSetBCD() function. This function
encodes a decNumber with "n" BCD digits. The original code erroneously
computed the number of declets from the dn argument, which is the output
decNumber value, and hence may contain garbage. Instead, the input "n"
value is used.

Introduce a new conversion function to the libdecnumber library.
This function converts a decNumber to a signed 64-bit integer.
In order to support 64-bit integers (which may have up to 19
decimal digits), the existing "powers of 10" array is expanded
from 10 to 19 entries.

Introduce two conversion functions to the libdecnumber library.
These conversions transform 64 bit integers to the internal decNumber
representation. Both a signed and unsigned version is added.

Eliminate an unused variable in the decSetSubnormal routine. The
variable dnexp is declared and eventually set but never used, and
thus may trigger an unused-but-set-variable warning.

Eliminate redundant declarations of symbols DPD2BIN and BIN2DPD in
various .c source files. These symbols are already declared in decDPD.h and
thus will trigger 'redundant redeclaration of ?XXX?' warnings, which, of
course, may fail QEMU compilation.

Consistent with other libraries in QEMU, the libdecnumber header files were
placed in include/libdecnumber, separate from the C code. This is different
from the original libdecnumber source, where they were co-located.
Change the libdecnumber source code so that it reflects this split. Specifically,
modify directives of the form:
#include "xxx.h"
to look like:
#include "libdecnumber/xxx.h"

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+.
