StdLib: Fix issue with Canonical output expansion of NL to CR NL and similar expansions.
SysCalls.c: Add IGNSPEC to the "sane" termios settings so that, by default, function keys and other special keys are ignored.
fvwrite.c:
Line 109: Change test to less-than zero since zero is a valid value.
Line 113: Change test to greater-than zero since we only want to loop when there are characters available.
Line 114: Force uio_resid to zero since it might have become negative on line 113.
