Ensure tshark/wireshark always get good err msgs from dumpcap:

1. Clean up dumpcap 'as a child' err msg handling so that:
   - all err msgs are properly formatted when being sent 
     back to the parent.
   - any log Critical, Warning, etc messages
     are sent back to parent and are properly formatted.
2. Change handling of -w <...> slightly in capture_opts.c
   so that wireshark provides a good error message if
   there is a 'write permissions' issue on the file.
   (Previously the error popup said only 
   "Child exited with status 2").
   This fixes bug #2288.

Add some conditionalized DEBUG_CHILD_DUMPCAP code for
   dumpcap debug logging to a file.
