SIGINT is a bad choice for changing log levels

[Nick Hibma]

Guus,

I would like to ask you to reconsider using SIGINT for logging change. It’s a pain to kill tincd when started from the command line. Ctrl-C does not work as expected. Great for debugging perhaps, but in normal use cases, when trying to make a connection work and test changes it’s a pain.

On BSD there is SIGINFO (29), which can be sent by pressing Ctrl-T, but I am not sure whether that exists on all Linuxes.
