The attached patch is the third revision of my attempt to enable memory

Printing a message to the standard error and exiting if ring corruption
is found is probably not the best approach. Instead, it should probably:
set the error string on the pcap_t to the error message;
set most of the function pointers to routines that just return an error
indication (except for the close routine);
return an error indication;
so that the application can report the error as appropriate and close
the pcap_t.
This would let GUI applications, for example, display the message in the
GUI, and would even let tty-based applications gracefully close any
capture file they're writing.
