[PATCH] saner handling of argument lists
This does two things:
a) get C99 varargs to use the same mechanism as gcc ones use - all
we need is to internally convert final ... in the list to ident[__VA_ARGS__]
and set its ->next to &variable_argument. After that we don't need any
special-casing for them.
b) take parsing the argument list in a separate function and does
it with all sanity checks; normally it ends up with fewer tests than old
variant.
