Regen test cases for yacc(1) after r274460.  YYINT is int now.

Remove the no-at variants of the kern_xx() syscall helpers.  E.g., we
have both kern_open() and kern_openat(); change the callers to use
kern_openat().

This removes one (sometimes two) levels of indirection and
consolidates arguments checks.

Fix assertion, &uc->uc_busy is never zero, the intent is to test the
uc_busy value, and not its address [1].

Remove the single use of the macro, write KASSERT() explicitely in the
code of umtxq_sleep_pi().

Remove reference to sys/dev/dpt/dpt_control.c.  It was removed back in 2001 after having
never been updated for CAM changes in 1998.
Remove dpt_isa.c and commented out references to it.  It was never connected
to the build in either sys/conf/files* or sys/modules/dpt/Makefile.  Also,
it was denoted as "doesn't quite work yet" when the file was initially added
(which may account for it never having been hooked up to the build).
Drop mention of ISA cards.  Note that I have no idea what to cull from the
supported hardware list.  Judging by the PCI driver attachment, dpt_pci.c
only supports a single adapter rather than the various PCI adapters listed.
The list of EISA adapters listed somewhat overlaps with the device IDs in
dpt_eisa.c.  It's not clear which devices are ISA-only devices.
filedesc: fixup fdinit to lock fdp and preapare files conditinally

Not all consumers providing fdp to copy from want files.

Perhaps these functions should be reorganized to better express the outcome.

This fixes up panics after r273895 .

﻿The fix imported into llvm in r274442 contains some C++11 constructs,
which gcc in base cannot handle.  Replace these with C++98 equivalents.

While here, add the patch for the adapted fix.

Lock iir(4) and mark it MPSAFE.
- Add a per-device mutex to the softc and use it for bus_dma tags,
  CAM SIMs, callouts, and interrupt handler.
- Switch from timeout(9) to callout(9).
- Add a separate global mutex to protect the global event buffer ring.
- Return completed index from iir_intr_locked() and remove the global
  gdt_wait_* variables.
- Remove global list of gdt softcs and replace its use with
  devclass_get_device().
- Use si_drv1 to store softc pointer in the SDEV_PER_HBA case instead
  of minor numbers.
- Do math on osreldate instead of dubious char math on osrelease[]
  that didn't work on 10.0+.
- Use bus_*() instead of bus_space_*().
- Use device_printf() instead of printf() with a unit number.

Migrate the callouts from using mutex locks to being mpsafe with
the locks being held by the callers.

Kill callout_drain() and use callout_stop().
There should not be zero length mbufs in socket buffers.  The code comes
from r1451, and thus can't be explained.  A patch with explicit panic()
here survived all tests.
