kbd: patch linker set methods, too

This is needed after r355796. Some double-registration of kbd drivers needs
to be sorted out, then this sysinit will simply add these drivers into the
normal list and kill off any other bits in the driver that are aware of the
linker set, for simplicity.

textproc/py-genshi: Update to 0.7.3

Genshi 0.7 doesn't support Python 3.5+, but the port currently allows it
to be built with any Python version. This doesn't affect the build, but
produces a broken runtime, including for all Genshi dependents:

Genshi (0.7) tests:

  2.7: Ran 854 tests in 3.623s - FAILED (failures=1)
  3.5: Ran 858 tests in 3.607s - FAILED (failures=4, errors=34)
  3.6: Ran 858 tests in 3.610s - FAILED (failures=4, errors=34)
  3.7: Ran 858 tests in 3.313s - FAILED (failures=11, errors=91)
  3.8: Ran 858 tests in 3.094s - FAILED (failures=32, errors=359)

Genshi added 3.5+ support in subsequent versions [1]:

  0.7.2: Add support for Python 3.8.
  0.7.1: Add support for Python 3.5, 3.6 and 3.7

Given Genshi 0.7 -> 0.7.3 involves only additional Python version support
and bugfix-only changes, this change updates the port to 0.7.3, instead of
restricting (correctly) its use to USES=python:-3.4, and is intended to be
merged to the quarterly branch accordingly.

kbd: remove kbdsw, store pointer to driver in each keyboard_t

The previous implementation relied on a kbdsw array that mirrored the global
keyboards array. This is fine, but also requires extra locking consideration
when accessing to ensure that it's not being resized as new keyboards are
added.

The extra pointer costs little in a struct that there are relatively few of
on any given system, and simplifies locking requirements ever-so-slightly as
we only need to consider the locking requirements of whichever method is
being invoked.

__FreeBSD_version is bumped as any kbd modules will need rebuilt following
this change.

kbd: provide default implementations of get_fkeystr/diag

Most keyboard drivers are using the genkbd implementations as it is;
formally use them for any that aren't set and make
genkbd_get_fkeystr/genkbd_diag private.

MFC r355670:

Rather than pass the address of the packet information control block to
ipf_pcksum6(), directly pass the adddress of the mbuf to it. This reduces
one pointer dereference. ipf_pcksum6() doesn't use the packet information
control block except to obtain the mbuf address.

keyboard switch definitions: standardize on c99 initializers

A future change will provide default implementations for some of these where
it makes sense and most of them are already using the genkbd

kbd drivers: use kbdd_* indirection for diag invocation

These invocations were directly calling enkbd_diag(), rather than
indirection back through kbdd_diag/kbdsw. While they're functionally
equivent, invoking kbdd_diag where feasible (i.e. not in a diag
implementation) makes it easier to visually identify locking needs in these
other drivers.

vfs: allow tail call optimisation in vops in the common case

Most frequently used vops boil down to checking SDT probes, doing the call and
checking again. There is no vop_post/pre in their case but the check after the
call prevents tail call optimisation from taking place. Instead, check once
upfront. Kernels with debug or vops with non-empty vop_post still don't short
circuit.

Apply a small optimization to pmap_remove_l3_range().  Specifically, hoist a
PHYS_TO_VM_PAGE() operation that always returns the same vm_page_t out of
the loop.  (Since arm64 is configured as VM_PHYSSEG_SPARSE, the
implementation of PHYS_TO_VM_PAGE() is more costly than that of
VM_PHYSSEG_DENSE platforms, like amd64.)

loader: rewrite zfs vdev initialization

In some cases the pool discovery will get stuck in infinite loop while setting
up the vdev children.

To fix, we split the vdev setup into two parts, first we create vdevs based on
configuration we do get from pool label, then, we process pool config from MOS
and update the pool config if needed.

Testing done: confirm previously hung loader is not hung any more.

schedlock 4/4

Don't hold the scheduler lock while doing context switches.  Instead we
unlock after selecting the new thread and switch within a spinlock
section leaving interrupts and preemption disabled to prevent local
concurrency.  This means that mi_switch() is entered with the thread
locked but returns without.  This dramatically simplifies scheduler
locking because we will not hold the schedlock while spinning on
blocked lock in switch.

This change has not been made to 4BSD but in principle it would be
more straightforward.

powerpc/powernv: Set the PTCR for the Nest MMU

The Nest MMU manages address translation for accelerators on the POWER9.  To
do so, it needs a page table, so export the system page table to the Nest
MMU.  This will quietly fail on pre-POWER9 systems that do not have a NMMU.

The NMMU is currently unused, so this change is currently effectively a NOP,
but the NMMU and VAS will eventually be used.

Rewrite arm kernel stack unwind code to work when unwinding through modules.

The arm kernel stack unwinder has apparently never been able to unwind when
the path of execution leads through a kernel module. There was code that
tried to handle modules by looking for the unwind data in them, but it did
so by trying to find symbols which have never existed in arm kernel
modules. That caused the unwind code to panic, and because part of panic
handling calls into the unwind code, that just created a recursion loop.

Locating the unwind data in a loaded module requires accessing the Elf
section headers to find the SHT_ARM_EXIDX section. For preloaded modules
those headers are present in a metadata blob. For dynamically loaded
modules, the headers are present only while the loading is in progress; the
memory is freed once the module is ready to use. For that reason, there is
new code in kern/link_elf.c, wrapped in #ifdef __arm__, to extract the
unwind info while the headers are loaded. The values are saved into new
fields in the linker_file structure which are also conditional on __arm__.

In arm/unwind.c there is new code to locally cache the per-module info
needed to find the unwind tables. The local cache is crafted for lockless
read access, because the unwind code often needs to run in context where
sleeping is not allowed.  A large comment block describes the local cache
list, so I won't repeat it all here.

schedlock 1/4

Eliminate recursion from most thread_lock consumers.  Return from
sched_add() without the thread_lock held.  This eliminates unnecessary
atomics and lock word loads as well as reducing the hold time for
scheduler locks.  This will eventually allow for lockless remote adds.
