directories when they are not wanted/required.

108b31e284 Switched from using -fstack-protector to -fstack-protector-strong compile
flag. Tested with both GCC and Clang.

bed25016b1 Updated sulogin.c to pull in crypt.h as it is a new, undocumented
dependency on Fedora 28.
Confirmed we can still build on other/older platforms.

e0cfd39728 Added "Fall through" comments to some switch statements where multiple
approaches are tried in order to prevent warnings from GCC 7 (and newer).

Added includes on Linux for sys/sysmacros.h as the old defines in
the sys/types.h file will be removed in the future.

272f112c98 Added new signal handler for SIGUSR2. When init receives SIGUSR2
it closes (and leaves closed) the named pipe /run/initctl. This
can be used to make sure init does not have any files open. However,
it also means we cannot switch run levels or bring down the system.
The pipe can be re-opened by sending init the SIGUSR1 signal.

Updated the man pages for initctl and init to include this information.

f09da9cb55 Add check to make sure /run/initctl is open before we try to close
it when receiving SIGUSR1. Avoids crashing upon receiving signal.

aee28b3292 Updated init page to reference the initctl manual page instead of
telling people to read the source code to learn how to use
the /run/initctl named pipe. Updated Makefile to install
the initctl.5 manual page.

a4508479f5 Updated shutdown to check if time has lapsed when we did not
notice. For example if the computer was in sleep mode pending
a shutdown. The shutdown command now notices time has past
and adjusts its countdown clock to compensate. Accurate
to the nearest minute.
Closes Savannah bug #36279

d9b6475d85 Removed unneeded "count" variable in utmpdump.c.
Fixed typo in accidental wrote_wtmp_rlevel == 0 || wrote_wtmp_rlevel
comparison so the latter is wrote_utmp_rlevel.

Simplified logic in mountpoint.c when testing for same device or same inode.

Thanks to David Binderman for pointing out the above three issues.

8c8172349e Updated mountpoint to search for circular mount points when using
the -p parameter. This works around mountpoint not recognizing
circular mounts where /a/b/c/d and /a/b are the same location
(ie the same device and same inode).
Closes Savannah bug #37114.

2e1f87635e Removed extra sleep() calls from shutting down process since we use
sync() anyway to pause and make sure data is written out to disk.

986bee63c0 Allow multiple console output
When booting a kernel with multiple serial console support, or multuiple
console arguments ala "console=tty1 console=ttyS0,9600" the kernel will output
messages to all consoles, init however will not. It will only send output to,
and accept input from, the last of the consoles.
This patch fixes it.

80dbcf3de3 Moved the named communication pipe from /dev/initctl to /run/initctl. This
patch was supplied by Robert Millan from Debian. FreeBSD apparently does not
like named piped in /dev, so we move it to /run for better cross-platform
compatibility.

6e3e87bf32 Patch to automatically spawn agetty on kernel consoles
The feature is useful for developers and admins that occasionally need
to boot with e.g. console=ttyS0.
The built in default can be overridden via inittab for each device. An
entry like "S0::off:" turns off the getty on ttyS0.
