POSIX used to specify those declarations, but later removed them.

actually remove this header. It was originally added for ports, which is
malloc.h-free now.

The 'A' option elevated warnings to errors, and has been the default for some
time. Then warnings were effectively eliminated in favor of everything
being an error, but then the 'a' flag turned real errors into warnings!
Remove the 'a' option entirely. You shouldn't have used it anyway.

Work around this particular case by reseeding whenever pid=1, but as guenther@
notes, directly calling clone(2), and then forking to match another pid,
provides other ways to bypass new process detection on Linux.
Hopefully at some point Linux implements something like MAP_INHERIT_ZERO, and
does not invent a corresponding mechanism to subvert it.

This patch adds a new driver for use of virtio-console devices as
ttys.  It's still in an early state and not compiled by default, yet.
Currently it is only wired into amd64. i386 is still missing.

the daemon is actually running (instead of only when using rc_bg).
This *may* trigger the following side effect: if a daemon starts then stops
right away (because of a config parsing issue for e.g.), then it will slow down
the boot process because rc will wait a bit before considering the start action
failed. But at least it will allow us to detect those daemons and fix them or
their rc.d(8) script.
At least as far as I can tell, all base daemons should cope with it just fine.

and actually not a "logging" function.  No functional change.

tell you that the daemon succesfully started; prevent this by running a config
check first.
Note that we only do this for those particular daemons, not all that support a
config test mode.
