When converting long double values to integer types, explicitly use the
...
"round to zero" variants of the softfloat conversion functions.
Add a variant to convert long double to unsigned long - the "to long"
variant checked for overflows that do not apply to unsigned results.
This fixes the regress/lib/libc/convfp tests for sparc64.

quoting Matthias Drochner:
> -check for a NULL uc_link before calling setcontext(2); do a real exit(3)
> instead with exit handlers and all that
> -If setcontext(2) returns (which it shouldn't), do an _exit(-1) rather

This also fixes regress/lib/libc/context for sparc64.

Push back the descriptions of NaN formats, and descriptions of the
...
distinction between signalling NaNs and quiet NaNs back into the
machine-dependent headers; treat the implementation of __nanf in the
same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.
