v1.9.17
No longer need to define NSIG for cppcheck.
Use #include <foo.h> instead of #include "foo.h" in most cases.
Allow multiple accept/reject messages during a logsrv conversation. The log server now advertises a subcommands flag if it supports logging subcommands (e.g. commands run from a sudo-spawned program like a shell). The client should only log additional commands during a session if this flag is set in the ServerHello message.
