Metadata for strings optionally requiring zero termination

[recombinant]

The issue is that some win32 string pointer parameters accept strings that are optionally zero terminated. The associated length parameter determines the length (e.g. TextOut()) or in some instances (e.g. DrawTextEx()) a length parameter of -1 can allow the string to be zero terminated.

There is "NullNullTerm":false in the JSON metadata that appears to indicate where the parameter should be [*] rather than the current [0:*].
