Do not check whether AcpiOsGetTimer() is called during boot.

From ACPICA 20170929, AcpiOsGetTimer() should be available early because
While() loop timeout mechanism was reimplemented with it. Unfortunately,
it means AcpiLoadTables() may cause panic when a While() loop is executed.
After having lengthy discussions with ACPICA developers, I have concluded
that dummy timecounter is good enough for the purpose and it is the least
intrusive solution for now. Also, they reminded me the ACPI specification
implies OS timer function should be available before loading tables.

Defer ACPI taskqueue creation to SI_SUB_KICK_SCHEDULER.

This addresses a deadlock during boot when EARLY_AP_STARTUP is configured:
a taskqueue thread may call pause() with an ACPI mutex held, and thread0
may block on this mutex before configuring the eventtimer. In this case
the taskqueue thread will sleep forever waiting for its callout to fire.

Extend the meaning of the CTLFLAG_TUN flag to automatically check if
there is an environment variable which shall initialize the SYSCTL
during early boot. This works for all SYSCTL types both statically and
dynamically created ones, except for the SYSCTL NODE type and SYSCTLs
which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to
be used in the case a tunable sysctl has a custom initialisation
function allowing the sysctl to still be marked as a tunable. The
kernel SYSCTL API is mostly the same, with a few exceptions for some
special operations like iterating childrens of a static/extern SYSCTL
node. This operation should probably be made into a factored out
common macro, hence some device drivers use this. The reason for
changing the SYSCTL API was the need for a SYSCTL parent OID pointer
and not only the SYSCTL parent OID list pointer in order to quickly
generate the sysctl path. The motivation behind this patch is to avoid
parameter loading cludges inside the OFED driver subsystem. Instead of
adding special code to the OFED driver subsystem to post-load tunables
into dynamically created sysctls, we generalize this in the kernel.

Other changes:
- Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask"
to "hw.pcic.intr_mask".
- Removed redundant TUNABLE statements throughout the kernel.
- Some minor code rewrites in connection to removing not needed
TUNABLE statements.
- Added a missing SYSCTL_DECL().
- Wrapped two very long lines.
- Avoid malloc()/free() inside sysctl string handling, in case it is
called to initialize a sysctl from a tunable, hence malloc()/free() is
not ready when sysctls from the sysctl dataset are registered.
- Bumped FreeBSD version to indicate SYSCTL API change.
