Markus Armbruster 965379b455 libdecnumber: Don't error out on decNumberLocal.h re-inclusion
decNumberLocal.h errors out when it's included with its header guard
defined.  This catches multiple inclusions.

Drop that.  Including it multiple times is safe, and the compiler can
do it efficiently.

Markus Armbruster 6031a51f1d libdecnumber: Don't fool around with guards to avoid #include
Some libdecnumber headers avoid including decNumber.h or decContext.h
again by checking their header guards.  Don't.  Including them
multiple times is safe, and the compiler can do it efficiently.

Markus Armbruster 121d07125b Clean up header guards that don't match their file name
Header guard symbols should match their file name to make guard
collisions less likely.  Offenders found with
scripts/clean-header-guards.pl -vn.

Cleaned up with scripts/clean-header-guards.pl, followed by some
renaming of new guard symbols picked by the script to better ones.

Peter Maydell 90ce6e2644 include: Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes.

NB: If this commit breaks compilation for your out-of-tree
patchseries or fork, then you need to make sure you add
#include "qemu/osdep.h" to any new .c files that you have.

Tom Musta 79af357225 libdecnumber: Introduce decNumberIntegralToInt64
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.

Tom Musta 8e706db21e libdecnumber: Introduce decNumberFrom[U]Int64
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.

Tom Musta 7275585b8c libdecnumber: Modify dconfig.h to Integrate with QEMU
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.

Tom Musta 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"

Tom Musta 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+.
