Jordan Rose 16d52a2a72 Don't require nullability on 'va_list'.
There are many non-portable typedefs, but va_list is one that nobody
ever thinks of as a pointer or an array. (When's the last time you saw
someone check for a NULL va_list?) Make an exception for this one
special type.

Jordan Rose f85a9b06b8 Add -Wnullability-completeness-on-arrays.
This is an addition to (and sub-warning of) -Wnullability-completeness
that warns when an array parameter is missing nullability. When the
specific warning is switched off, the compiler falls back to only
warning on pointer types written as pointer types.

Note that use of nullability /within/ an array triggers the
completeness checks regardless of whether or not the array-specific
warning is enabled; the intent there is simply to determine whether a
particular header is trying to be nullability-aware at all.
