139c1837db meson: rename included C source files to .c.inc
With Makefiles that have automatically generated dependencies, you
generated includes are set as dependencies of the Makefile, so that they
are built before everything else and they are available when first
building the .c files.

Alternatively you can use a fine-grained dependency, e.g.

        target/arm/translate.o: target/arm/decode-neon-shared.inc.c

With Meson you have only one choice and it is a third option, namely
"build at the beginning of the corresponding target"; the way you
express it is to list the includes in the sources of that target.

The problem is that Meson decides if something is a source vs. a
generated include by looking at the extension: '.c', '.cc', '.m', '.C'
are sources, while everything else is considered an include---including
'.inc.c'.

Use '.c.inc' to avoid this, as it is consistent with our other convention
of using '.rst.inc' for included reStructuredText files.  The editorconfig
file is adjusted.

5d64abb32f softfloat: Support float_round_to_odd more places
Previously this was only supported for roundAndPackFloat64.

New support in round_canonical, round_to_int, float128_round_to_int,
roundAndPackFloat32, roundAndPackInt32, roundAndPackInt64,
roundAndPackUint64.  This does not include any of the floatx80 routines,
as we do not have users for that rounding mode there.

3ac1f81329 tests/fp/fp-test: add floating point tests
By leveraging berkeley's softfloat and testfloat.

With this we get decent coverage of softfloat.c:

$ ./fp-test -r even:	67.22% coverage
$ ./fp-test -r all:	73.11% coverage

Note that we do not yet test parts of softfloat.c that aren't
in the original softfloat library, namely:

- denormal inputs
- *_to_int16/uint16 conversions
- scalbn for fixed point
- muladd variants
- min/max
- exp2
- log2
- float*_compare (except float16_compare)
