Systematically include sys/featuretest.h when _NETBSD_SOURCE is used. Some are redundant, but make verification with grep much easier.

Move some files out of i386 into x86, so that they can be shared with other ports.

* Move the definitions for types other than single-precision and double- precision back to machine-dependent headers. C99 has no strict requirement which, if any, extended-precision type `long double' must match, and even between 80-bit formats there are differences in implementation (m68k vs. x86). * On arm, consider __VFP_FP__.
