Have changed IO channels to stdio. I didn't have any particular reason for
using them, I just noticed that wireshark was using glib and I checked for file
handing functions in the glib reference.

The reason for the constant re-reading of the keylog file is that my typical
use case is that the client is running concurrently with wireshark on the same
host. So the client writes the keylog line just before writing to the socket
and then wireshark can find it a few milliseconds later.

Agreed. But I'm going to punt on that for now :)

Dropped.

The code is only compiled into NSS if you build it with DEBUG and TRACE
defined. (This is mainly for security reasons: we wouldn't want this stuff in
normal builds). However, NSS and libssl3 are shared libraries, so you can build
NSS in debug mode and set LD_LIBRARY_PATH to use them with Firefox.
(Chrome is a little different. Chrome has its own copy of libssl because we
have local patches. There you would need to build *Chrome* in debug mode.)
