Using a drop-in instead of an extra service avoids having to juggle
between both services (especially since irqbalance_mck did not have a
Conflict=irqbalance.service statement)
That way, we only have a single service to check for (irqbalance.service),
and system administrators should find this less confusing if they normally
rely on irqbalance.
The drop-in is also installed in /run so will automatically disappear in
the event of a linux crash or a reboot without shutting down mckernel

mcoverlayfs code is now unused (technically should work on top of the
soft emulation but not well tested, and untested unused code is bad).
Remove it.
Left the unshare/bind_mount_recursive code in mcexec in a new
MCEXEC_BIND_MOUNT ifdef (only in config.h.in directly to discourage use.
it disables the ioctl as well, but the main code is still compiled to
keep up to date with linux api changes... although it's using kallsyms
lookup so it does not validate much more than "the symbol still exists")
I honestly think this should go as well (people who would want to use it
are root and could do it manually), but will give up for now.

Use lsof to check for processes that still open /dev/mcosX at shutdown
time.
If lsof is not installed then the check is just not done (empty PROCS
result)
If -k is not passed, print a message listing pids of users and exit
(taking bets someone will use that and sed to kill out of mcstop+release
and rerun the stop script instead of passing -k at some point)

Separate copyright bumps in a different commit.
A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats

While we are here:
- fix uname -r (single quote?!)
- add compat for rhel8 (el kernel and version is 4.18)
- also remove linux version check in mcreboot.sh, trust configure check

Add "-T 0" to mcreboot.sh if you want to turn off time sharing. When
it's turned off, McKernel doesn't activate interval timer when the
length of per-CPU run-queue is larger than one.
Change-Id: I2cedc1b30a9cd9a0f4608a32ecec0a0d58c6225e
It's enabled by adding -s to mcreboot.sh.
