Add KCOV - kernel code coverage tracing device

The KCOV driver implements collection of code coverage inside the kernel.
It can be enabled on a per process basis from userland, allowing the kernel
program counter to be collected during syscalls triggered by the same
process.

The device is oriented towards kernel fuzzers, in particular syzkaller.

Currently the only supported coverage type is -fsanitize-coverage=trace-pc.

The KCOV driver was initially developed in Linux. A driver based on the
same concept was then implemented in FreeBSD and OpenBSD.

Documentation is borrowed from OpenBSD and ATF tests from FreeBSD.

This patch has been prepared by Siddharth Muralee, improved by <maxv>
and polished by myself before importing into the mainline tree.

All ATF tests pass.

Remove wrong KASSERT in EPT, and reorder the code to reduce duplication.

Reorder the detection in vmx_ident(), to fix panic on old CPUs. We must
read MSR_IA32_VMX_EPT_VPID_CAP _after_ ensuring EPT is there, because if
it's not, the rdmsr faults.

(maxv)

Another locking issue in NVMM: the {svm,vmx}_tlb_flush functions take VCPU
mutexes which can sleep, but their context does not allow it.

Rewrite the TLB handling code to fix that. It becomes a bit complex. In
short, we use a per-VM generation number, which we increase on each TLB
flush, before sending a broadcast IPI to everybody. The IPIs cause a
#VMEXIT of each VCPU, and each VCPU Loop will synchronize the per-VM gen
with a per-VCPU copy, and apply the flushes as neededi lazily.

The behavior differs between AMD and Intel; in short, on Intel we don't
flush the hTLB (EPT cache) if a context switch of a VCPU occurs, so now,
we need to maintain a kcpuset to know which VCPU's hTLBs are active on
which hCPU. This creates some redundancy on Intel, ie there are cases
where we flush the hTLB several times unnecessarily; but hTLB flushes are
very rare, so there is no real performance regression.

The thing is lock-less and non-blocking, so it solves our problem.

  most accesses to the mount with fstrans mount info.

- Add "fmi_gone" to be true after unmount and add a counter of
  outstanding mount infos so fstrans_clear_lwp_info() only runs
  if there may be something to do.

- Move lookup of base mounts into per-lwp state.

- Keep a list of valid mounts for DIAGNOSTIC checks.

(hannken)

Move fstrans_unmount() to vfs_rele(), just before it would free the mount.
Don't take a mount reference for fstrans as it gets notified about the release.

Defer the final free of the mount to fstrans_mount_dtor() when fstrans
has released all references to this mount.  Prevents the mount's memory
to be reused as a new mount before fstrans released all references.

Address PR kern/53928 modules/t_builtin:disable test case randomly fails.

(hannken)

Attach "mnt_transinfo" to "dead_rootmount" so every mount has a
valid "mnt_transinfo" and remove now unneeded flag IMNT_HAS_TRANS.

Run fstrans_start()/fstrans_done() on dead_rootmount if FSTRANS_DEAD_ENABLED.
Should become the default for DIAGNOSTIC in the future.

(hannken)

Assign vnode to dead_rootmount before vcache_dealloc() releases it.

Now v_mount is never NULL.

(hannken)

Set "mnt_lower" before the first file system operation on the new file system.

(hannken)

Bracket do_sys_renameat() and nfsrv_rename() with fstrans.

The v_mount field for vnodes on the same file system as "from"
is now stable for referenced vnodes.

VFS_RENAMELOCK no longer may use lock from an unreferenced and
freed "struct mount".

(hannken)

Fix vnode locking, must lock for VOP_OPEN() and VOP_UNLOCK() when done.

(hannken)

Remove superfluous VOP_UNLOCK(), vnode will be unlocked from spec_reclaim().

(hannken)

Make FSS_ERROR a flag to prevent bogus fscow_disestablish() after error.

(hannken)

Fix vnode locking for opendisk(), must lock for VOP_OPEN().

(hannken)

compat70_ocreds_valid is not a pointer to a boolean, it is the boolean
itself which controls whether or not we recognize the OCRED options.

Should fix the panic identified in PR kern/53991 (awaiting confirmation
from submitter).

Export atomic_cas_32_ni in a similar manner to its 64-bit counterpart.

Compile test only, but seems trivial enough for me.

Fix build error due to test/lib/libc/atomic/t_atomic_cas.

Note that mips32 does not use atomic_cas.S.
