AAAAAArgh.  The capture_input_new_XXX routines are called from
capture_sync.c, not from capture.c, so they should be declared in
capture_sync.h, so callers that use the capture_sync.c stuff but not the
capture.c stuff - such as TShark - get the declarations and get their
implementations compared with the signatures that they should have.

Doing so points out that some of them in TShark *don't*, so fix that.
