As discussed (briefly) on tech-userlevel, fix our quad support to work
...
correctly on LP64 platforms. This is mostly just s/long/int/ where
appropriate.

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

The comment above the code mentions that it should work even on machines
that shift in zeroes.

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
doesn't happen much in actual practice.
These changes make these functions considerably smaller and faster.

equivalent code on the sparc.
