From Graeme Hewson:
Allow "-" as the output file name in Wiretap, referring to the
standard error.
Optimize the capture loop.
Fix some of the error-message printing code in Ethereal and Tethereal.
Have Wiretap check whether it can seek on a file descriptor, and pass
the results of that test to the file-type-specific "open for output"
routine. Have the "open for output" routines for files where we need to
seek when writing the file return an error if seeks don't work.
