  Rewrite native_pbc number converters and fix format errors

Fix wrong layout of intel 80-bit long double, it is 10-byte + 2/6 byte padding
in i386 resp. x86_64/itanium. Renamed to FLOATTYPE_10.
Older pbc contain a wrong floattype=2 for this format.
It only depends on the word size: on 32bit padded to 12 byte, on 64 to 16byte.
Fixed the header writer logic accordingly.

Add single float support FLOATTYPE_4.

Add detection of yet unsupported special ppc, mips and aix variants
and the official IEEE-754 __float128 (quad double) format, which only
Sparc64 supports.

Simplify endianizers on number converters to reduce complexity.
Use native byteswap.h if detected (not yet).
New and better number.pasm values.

  Log Message:
  -----------
  pre-calculate FLOATTYPE

FLOATTYPE is cpu dependent for long double. Better do that
in a config step, not at run-time.
Improve __float128 support.

E.g. with long double used and __float128 possible hugefloatvalsize
is 16

Add generated ppc pbcs

  Configure probes for format, sizes, ranges and digits

Probe FLOATVAL_FMT/floatvalfmt with float round-trip precision tests.
Found that long double and __float128 on intel are
stable only with %17Lg. I.e. 17 digits precision in number-string round
trips. Do the precision test for all float types.

Also test for the cpp defines of ranges and DBL|FLT_DIG
(precision digits).

New config hash value for floatvaldig, the number of compiler
precision digits, which be different to the tested floatvalfmt.

Improved HAS_FLOAT128 detection.

Use HAS_INT64 instead of HAS_LONGLONG for bswap64.

  [GH #807] Refactor native_pbc endianness, bswap64. Add header argument to converters

Convert endianness upfront does not work.
Some converters work on native floats, to do compiler casts. They
need to know the packfile byteorder.
Other bitfiddling converters work only on little-endian, so we also need
to know the packfile byteorder, and they also need to convert endianness
back to to the target format.

Refactor bswap64, as it only works with 64bit registers. Tested with HAS_INT64.
So there are two bswap64 API's, one for fast native conversion via a register
and one with two unsigned char * args, which might point to the same buffer,
for easier in-place conversion.

Added dummy ROUND_NUM_TO macro, which needs to round a long number down to the given
precision (when converting upwards). Can be done with sprintf, but need to find a
better way.

Simplify converter casts with unions.

Replace SWAB_12 with SWAB_10. TODO: Need to check the last two bytes.
