The parsing of '--early-output' with or without its optional integer
argument allowed bogus options like '--early-output-foobarbaz' to slip
through and be ignored.
Fix it by parsing '--early-output' in the same way as other options
with an optional argument are parsed. Furthermore, use strtoul_ui()
to parse the optional integer argument and to refuse negative numbers.
While at it, use skip_prefix() instead of starts_with() and magic
numbers.
