abfa3c39e7 Use capsicum_helpers(3) that allow us to simplify the code and its functions
will return success when the kernel is built without support of
the capability mode.

It is important to note, that I'm taking a more conservative approach
with these changes and it will be done in small steps.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

09fd42cb88 Re-adding an event to a kqueue modifies the parameters of the original event.
However, if the original knote had been disabled then it is not automatically
re-enabled.

Fix this by using EV_ADD to create an mevent and EV_ENABLE to enable it.

Adding a kevent for the first time implicitly enables it so existing callers
of mevent_add() don't need to change.

058e24d34b Extend the ACPI power management support to wire a virtual power button up
to SIGTERM when ACPI is enabled.  Sending SIGTERM to the hypervisor when an
ACPI-aware OS is running will now trigger a soft-off allowing for a graceful
shutdown of the guest.
- Move constants for ACPI-related registers to acpi.h.
- Implement an SMI_CMD register with commands to enable and disable ACPI.
  Currently the only change when ACPI is enabled is to enable the virtual
  power button via SIGTERM.
- Implement a fixed-feature power button when ACPI is enabled by asserting
  PWRBTN_STS in PM1_EVT when SIGTERM is received.
- Add support for EVFILT_SIGNAL events to mevent.
- Implement support for the ACPI system command interrupt (SCI) and assert
  it when needed based on the values in PM1_EVT.  Mark the SCI as active-low
  and level triggered in the MADT and MP Table.
- Mark PCI interrupts in the MP Table as active-low in addition to level
  triggered.

7f5487aca1 Add the VM name to the process name with setproctitle().
Remove the VM name from some of the thread-naming calls
since it is now in the proc title.
Slightly modify the thread-naming for the net and block
threads.

This improves readability when using top/ps with the -a
and -H options on a system with a large number of bhyve VMs.

151dba4a87 Add simplistic periodic timer support to mevent using kqueue's
timer support. This should be enough for the emulation of
h/w periodic timers (and no more) e.g. some of the 8254's
more esoteric modes that happen to be used by non-FreeBSD o/s's.

4e8c7465ad Change thread name for the main kqueue event loop to "<vmname> mevent" so
it can be easily distinguished from other non-vCPU threads in forthcoming
changes.
