bfa3ab6197 remove libdecnumber/dpd/decimal128Local.h
Commit 72ac97cdfc added two equivalent versions of decimal128Local.h,
one in libdecnumber/dpd/ and another in include/libdecnumber/dpd/.
Being identical by the code, the two files however differs in the
licensing terms.  The one in libdecnumber/dpd/ (which is being
removed by this patch) is licensed as GPL3.1 (plus gcc runtime
exception), which, as far as I know, is not compatible with GPL-2.
This file is not used (it is included from
include/libdecnumber/dpd/decimal128.h, so version in include/ is
used).

More, the version in include/ can also be removed, since none
of the 3 defines from that file are actually used by the code.
Even more, one of the defines from there, decimal128SetSign,
is redefined (to equivalent value) in libdecnumber/dpd/decimal128.c,
but again, never used.

What a mess...

426d9a1a59 libdecnumber: Eliminate redundant declarations
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.

0f2d373220 libdecnumber: Prepare libdecnumber for QEMU include structure
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"

72ac97cdfc libdecnumber: Introduce libdecnumber Code
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+.
