Add --no-sigsegv option to accel-pppd
It's often useful to let a program crash on SIGSEGV and let an external
daemon, like monit or systemd, restart it when needed. This allows to
generate core dumps and do post-mortem analysis based on the collected
traces.
This patch add the new '--no-sigsegv' option to disable accel-ppp's
SIGSEGV handler and use the system's core(5) mechanism instead.
