panic: print backtrace on panic
...
Panics currently lack backtraces, which are a very useful thing to
have. Make the profiling backtrace function generic and print backtraces
using it.

kcov: move thread attach from open to start
...
The current kcov code attaches a kcov object to the thread which opened
it. This is not desirable, as syzkaller opens /dev/kcov in a parent
process and passes it down to the child.
Move the thread attachment from open() time to start time.

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.

devfs: add anonymous variants to register/remove
...
The current devfs code requires registered devices to have a name on
creation. This makes temporary/hidden devices like pty master ends
appear for a split second on the devfs tree.
Add a way of registering/removing devfs nodes which do not have a name
on the tree.
