commit f3ac83df5c4fec3f27a9c8f95ef2753a26c65d24

Enable daemon monitoring and automatic restart by default.
Tested on a XenServer by running "kill -SEGV" on the daemon processes and
watching them restart automatically and by running plain "kill" and
watching them terminate normally.
commit ff8decf1a318b4a611cb08bb3f12833044e8a872

daemon: Refactor code.
This commit should not change behavior, but it paves the way for
implementing --monitor in the following commit.

tests: New macro OVS_WAIT_WHILE.
For use by upcoming tests.
commit 24c8ae53303ff25d118bb96d237da21a32085160

tests: Factor OVSDB_INIT out of OVS_VSCTL_SETUP for other tests to use.
New tests in upcoming commits will use this.
commit e3830e909d210145cbe52a1da66058ebf2581fd6

fatal-signal: After fork, clear hooks instead of disabling them.
Until now, fatal_signal_fork() has simply disabled all the fatal signal
callback hooks. This worked fine, because a daemon process forked only
once and the parent didn't do much before it exited.
But upcoming commits will introduce a --monitor option, which requires
processes to fork multiple times. Sometimes the parent process will fork,
then run for a while, then fork again. It's not good to disable the
hooks in the child process in such a case, because that prevents e.g.
pidfiles from being removed at the child's exit.
So this commit changes the semantics of fatal_signal_fork() to just
clearing out hooks. After hooks are cleared, new hooks can be added and
will be executed on process termination in the usual way.
This commit also introduces a cancellation callback function so that a
canceled hook can free resources.

unixctl: Avoid double error reporting.
All of these programs were re-reporting an error that
unixctl_server_create() had already reported. There's no need for that.

Diffs: http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=commitdiff;h=a723bf84fb639262d2bf7e33b7640a9621bb19b5

unixctl: Improve error reporting.
The ovs_error() function is our standard way of reporting startup errors,
so use it. (It also outputs the program name at the beginning of the
message.)
