kcov: initial implementation
...
Implement a device (/dev/kcov) that exposes coverage info for the
kernel. This will be especially useful for coverage-based fuzzing (e.g.
syzkaller).
Exclude a lot of functions which would crash/otherwise interfere in the
coverage, including only processing coverage callbacks when not handling
an irq.

cpu: add irq depth counting
...
Add a way of checking if a cpu is in the middle of handling an irq and
how deep it is into it. This will allow for future code to conditionally
run only in/outside interrupts.

smp: fix race between cpu exposure and smp init
...
The SMP code exposes that a cpu woke up before it is properly
initialized in sched_ap_entry(). Fix this by initializing it first,
exposing it and then stopping the bootstrap thread.

scheduler: only run load balance when appropriate
...
Prevent the load balancer from balancing when running uniprocessor
machines and when not all CPUs are online yet.
This prevents a race between ap initialization and load balancing.

print: add nouserprint argument
...
For some usecases, silencing syscall_print()s is ideal. A good example
of that is syzkaller, which uses logs to detect crashes and a badly
timed syscall_print() could interfere.
Add a nouserprint argument which skips printing on syscall_print().
