  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.
