Assign quad / softfloat specific ${SRCS} to ${SRCS.quad} / ${SRCS.softfloat}

then append them to ${SRCS}. Those will be used to generate quad / softfloat
symbol lists.

Revert previous change: the assertion
...
* is made in a utility function with file scope only, and
* will never fail.

* use _DIAGASSERT() to check pointer arguments against NULL and file
...
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.
the first two items result in the addition of code similar to the
following in various functions:
_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

Don't special case shift counts > QUAD_BITS or == 0. The former is

undefined behavior (so we can do whatever we want) while the latter
