igc.4: Remove non-existent timer tunables
These were removed in a40ecb6f7405 because they do not apply to igc

dtrace: Add some more annotations for KMSAN
- Don't allow FBT and kinst to instrument the KMSAN runtime.
- When fetching data from the traced thread's stack, mark it as
initialized. It may well be uninitialized, but as dtrace permits
arbitrary inspection of kernel memory, it isn't very useful to raise
KMSAN reports.
- Mark data copied in from userspace as initialized, as we do for
copyin() etc. using interceptors.

rtld/arm: fix initial-exec (IE) thread-local storage relocation
net/frr[89] revealed an interesting edge-case on arm when dynamically
linking a shared library that declares more than one static TLS variable
with at least one using the "initial-exec" TLS model. In the case
of frr[89], this library was libfrr.so which essentially does the
following:
#include <stdio.h>
#include "lib.h"
static __thread int *a
__attribute__((tls_model("initial-exec")));
void lib_test()

dtrace: Avoid excessive pcpu allocations
We were previously allocating MAXCPU structures for several purposes,
but this is generally unnecessary and is quite excessive, especially
after MAXCPU was bumped to 1024 on amd64 and arm64. We already are
careful to allocate only as many per-CPU tracing buffers as are needed;
extend this to other allocations.
For example, in a 2-vCPU VM, the size of a consumer state structure
drops from 64KB to 128B. The size of the per-consumer `dts_buffer` and
`dts_aggbuffer` arrays shrink similarly. Ditto for pre-allocations of
local and global D variable storage space.

libthr: allow very early atfork registration
LSan wants to be able to register atfork handlers at __lsan_init time,
which can happen either at the first intercepted function call or in a
.preinit_array function. Both of these end up being very early in rtld
and executed with the bind lock held, which ends up causing problems
when we go to _libpthread_init().
Instead of requiring libpthread to be initialized, just insert the new
atfork handler straight into the list if it's not ready yet. The
critical section and locking should not be necessary if we're really
executing this early, as there won't be any threads to contend with.

_utmx_op: don't recurse on chain busy
In handling a PP mutex, we'll busy it as soon as we enter the loop and
unbusy it either prior to sleeping or at exit time. In this particular
case, if we fail to transition the mutex from OWNERDEAD -> owned because
of casueword(9) failure and the suspend check fails, we'll start over
and attempt to busy an already-busied chain and irrecoverably lock up
both this thread and anything else that tries to busy the chain.
Unbusy the chain prior to restarting because I couldn't decide if that
was a better or worse idea than just keeping track of whether we dirtied
it in do_lock_pp() and avoiding re-dirty. This is marginally easier to
reason about as it returns us to expected state on entry to the loop.
While we're here, simplify the code a bit as `error` will be clobbered
right after the branch anyways.
