Fix bug: scheme_to_interface must clear the floating-point register
stack. Otherwise, inexplicable floating-point errors can occur. An
example of such an error can be created by typing `-1e-194' at a
freshly-booted scheme.
The actual problem is somewhat involved. The C compiler assumes that
all of the floating-point registers are empty on the entry to any
procedure. As a consequence of this assumption, it feels free to use
all 8 of the registers. However, if this assumption is violated, a C
procedure that uses too many registers will signal a floating-point
stack overflow.
However, the Scheme compiler does not follow this convention; more
precisely, since it was originally designed to use reasonable
floating-point hardware, in which the floating-point registers are
organized as a bank of registers rather than a stack, it doesn't do
anything about popping registers when it is done with them. As a
consequence, floating-point operations generated by the Scheme
compiler often leave values on the floating-point stack.
To work around this without redesigning the compiler, the
compiled-code interface clears out the stack whenever it transfers
between C and Scheme code. The bug fixed by this revision was a
transfer point that did not have code to clear out the stack.

input buffer was empty.
* Change INPUT-BUFFER/READ-SUBSTRING to read a whole buffer from the
input channel if the required number of characters is less than the
size of the buffer.
* Change INPUT-BUFFER/READ-SUBSTRING to continue reading from the
input channel until the substring is filled or the channel has no
more characters available. This is a correct fix for the change
made in revision 14.47; this fix does a probe of the channel to
determine if there are any characters immediately available.
Previous to 14.47 the procedure might have blocked waiting for input
that was not ready, even if it had already partly filled the
substring. Now it will immediately return any characters that are
available, and block only when nothing is available.

Extensive changes to the code that gets information about files; new
code is smarter about reading protected files. Also add new
directory-reading primitive to allow the runtime system to get full
file-attribute information; this is otherwise impossible as the
directory reader is able to get file information that the
file-attribute calls can't.

Add new procedure to get all of the information from the directory
