Subject: Add support for clean shutdown via SIGTERM
X-Git-Url: https://the.earth.li/gitweb/?a=commitdiff_plain;h=6121bfeaf48b68f62c814ca094f5ffb2d32b7dc2;hp=6121bfeaf48b68f62c814ca094f5ffb2d32b7dc2;p=mqtt-arp.git

Add support for clean shutdown via SIGTERM

Catch SIGTERM to allow ourselves to do an orderly shutdown. This isn't
useful in general operation (as a TERM will do all this cleanup anyway)
but allows for testing under valgrind to ensure no leaks or invalid
accesses.
