Adjust dtrace_unload() definition to avoid clang 15 warning

With clang 15, the following -Werror warnings is produced:

In file included from sys/cddl/contrib/opensolaris/uts/common/dtrace/dtrace.c:18440:
sys/cddl/dev/dtrace/dtrace_unload.c:26:14: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
dtrace_unload()
^
void

This is because dtrace_unload() is declared with a (void) argument list,
but defined with an empty argument list. Make the definition match the
declaration.

Continue the crusade towards a dev_clone()-free kernel, removing its
usage from dtrace. The dtrace code already uses cdevpriv(9) since FreeBSD
8, so this change should be quite harmless.

MFC @ r259205 in preparation for some SVM updates. (for real this time)

Revert r260091. The vmem calls seem to be slower than the *_unr() calls that
they replaced, which is important considering that probe IDs are allocated
during process startup for USDT probes.

Now that vmem(9) is available, use vmem arenas to allocate probe and
aggregation IDs, as is done in the upstream illumos code. This still
requires some FreeBSD-specific code, as our vmem API is not i

Now that vmem(9) is available, use vmem arenas to allocate probe and

Initialize and free the DTrace taskqueue in the dtrace module load/unload
handlers rather than in the dtrace device open/close methods. The current
approach can cause a panic if the device is closed which the taskqueue
thread is active, or if a kernel module containing a provider is unloaded
while retained enablings are present and the dtrace device isn't opened.

Rename the kld_unload event handler to kld_unload_try, and add a new
kld_unload event handler which gets invoked after a linker file has been
successfully unloaded. The kld_unload and kld_load event handlers are now
invoked with the shared linker lock held, while kld_unload_try is invoked
with the lock exclusively held.

Convert hwpmc(4) to use these event handlers instead of having
kern_kldload() and kern_kldunload() invoke hwpmc(4) hooks whenever files are
loaded or unloaded. This has no functional effect, but simplifes the linker
code somewhat.
