In a Network Monitor capture file, get the starting offsets of frames
from the frame table - Network Monitor 2.x, at least, doesn't always
write frame N+1 right after frame N.
To do that, we need to mallocate a big array to hold the frame table,
and free it when we close the capture file; this requires that we have
capture-file-type-specific close routines as well as
capture-file-type-specific read routines - we let it the pointer to that
routine be null if it's not needed. Given that, we might as well get
rid of the switch statement in "wtap_close()", in favor of using
capture-file-type-specific close routines, as per the comment before
that switch statement.
