Otherwise we could cause leaks.
Most of the time this check should be optimized out,
as most uses of AutoDeleter don't invoke SetTo. But
it would have caught some bugs in the VFS refactors
(which wound up being cancelled out by later commits
anyway, but this would've exposed them.)
Just invoke debugger(), which calls the kernel
debugger when compiled in kernel mode. And define
debugger() inline in this header if OS.h is not
included to avoid namespace pollution.
It's not used for anything by the OS but userspace might want
to use it for its own purposes.

Also increase MSI message data size to 32 bits according to PCIe spec.
Remove 0xff check for MSI interrupts because it is potentially valid

- MSI-X supports up to 2048 interrupts per device that do not fit to
`uint8`.
- Non-x86 systems may use separate interrupt vector ranges for
hard-wired interrupts and MSI interrupts so `uint8` is not enough to
represent all of them.

* Rename the "tun" network device to "tunnel". FreeBSD calls theirs
"tuntap" but speaks of both TUN and TAP devices as interfaces for
tunnels. The other BSDs seem to do likewise.
* Fold the "tun" driver into the "tunnel" network device. The
network device now publishes entries in devfs when interfaces
are created, and unpublishes them when interfaces are destroyed.
This removes the need for the driver and device to communicate
through a file descriptor, and thus allows the receive queue
to be totally eliminated, massively simplifying that logic.
* Use standard net-stack FIFOs instead of TCP BufferQueue, which is
specialized to TCP's needs in far too many ways. Thanks to the
previous commit adding support for interrupting semaphore waits,
we can use the FIFO wait mechanisms, too.
* Restructure the TAP logic, and generate MAC addresses more like
Linux does.
* Actually set type = IFT_TUN, and use the "loopback" frame handler
instead of the "ethernet" frame handler. This allows significant
cleanup of the header handling logic.
* In TUN mode, reject packets that don't look like IP packets.
* Delete "tunconfig"; it was mostly stubs and is now unnecessary.
TUN mode tested and confirmed as working by kallisti5 with OpenVPN.
TAP mode partially tested, but not yet confirmed as working.
Fixes#18673.

While debugging some problems on the HaikuPorts build VMs, mmlr
noticed their clocks had an alarming amount of drift. This prompted
an investigation into TSC calibration mechanisms, and the discovery
that there is a VM-specific one which we did not implement.
This mechanism is more accurate than counting cycles on VMs where
cycles can be "stolen" (the probable cause of the aforementioned
clock drift.)
Tested in VMware (works out of the box) and on QEMU/KVM
(may need TSC frequency specified or a host with invariant TSC.)

* Always set next/previous to NULL even when DEBUG is not

Based on hamishm's original patch from 2015, but heavily modified,
refactored, and reworked.
From the original commit message:
> When an object is deleted, a B_EVENT_INVALID event is delivered,
> and the object is unregistered from the queue.
>
> The special event flag B_EVENT_ONE_SHOT can be passed in when adding
> an object so that the object is automatically unregistered when an
> event is delivered.
Modifications to the original change include:
* Removed the public interface (syscalls remain private for the moment)
* Event list queueing/dequeueing almost entirely rewritten, including:
- Clear events field when dequeueing.
- Have B_EVENT_QUEUED actually indicate whether the event has been
appended to the linked list (or not), based around lock state.
The previous logic was prone to races and double-insertions.
- "Modify" is now just "Deselect + Select" performed at once;
previously it could cause use-after-frees.
- Unlock for deselect only once at the end of dequeue.
- Handle INVALID events still in the queue upon destruction,
fixing memory leaks.
* Deduplified code with wait_for_objects.
* Use of C++ virtual dispatch instead of C-style enum + function calls,
and BReferenceable plus destructors for teardown.
* Removed select/modify/delete flags. Select/Modify are now the same
operation on the syscall interface, and "Delete" is done when 0
is passed for "events". Additionally, the events selected can be fetched
by passing -1 for "events".
* Implemented level-triggered mode.
* Use of BStackOrHeapArray and other convenience routines in syscalls.
