Only look for boostrap useful options:
- PACKAGESITE
- ABI
- MIRROR_TYPE
- ASSUME_ALWAYS_YES
While here makes PACKAGESITE expand the ${ABI} variable.
Allow to deactivate any SRV record look up (MIRROR_TYPE=none)
Use the same mechanism as for pkgng itself: first get configuration out of
environment variable and fallback on pkg.conf if exists.

This fixes a build error at the same time (unused variable "item"), if
the kernel is compiled without INVARIANTS.

Without this, read data is mis-interpreted. This could trigger a panic,
as was the case on one computer where computed "recsize" was zero,
leading to a call to g_read_page() asking for 0 bytes.
The early commit is done to facilitate the off-tree work on the
porting of the Radeon driver.

When the VirtIO barrier feature is not negotiated, the driver
must enforce the proper ordering for BIO_ORDERED BIOs. All the
in-flight BIOs must complete before starting the BIO, and the
ordered BIO must complete before subsequent BIOs can start.
Also fix a few whitespace nits.

being compiled only when setting LEGACY_TX, this means you would
not get the drain when needed on detach!!
Thanks to Bryan Venteicher (bryanv@freebsd.org) for catching this
little gremlin!! :)
Fixes:
- flow control - don't override user value on re-init
- fix to make 1G optics work correctly
- change to interrupt enabling - some bits were incorrect
for certain hardware.
- certain stats fixes, remove a duplicate increment of
ierror, thanks to Scott Long for pointing these out.
- shared code link interface changed, requiring some
core code changes to accomodate this.
- add an m_adj() to ETHER_ALIGN on the recieve side, this
was requested by Mike Karels, thanks Mike.
- Multicast code corrections also thanks to Mike Karels.
the pid provider on a kernel compiled with INVARIANTS.
sys/cddl/contrib/opensolaris/uts/intel/dtrace/fasttrap_isa.c:
In fasttrap_probe_pid(), attempts to write to the
address space of the thread that fired the probe
must be performed with the process of the thread
held. Use _PHOLD() to ensure this is the case.
In fasttrap_probe_pid(), use proc_write_regs() instead
of calling set_regs() directly. proc_write_regs()
performs invariant checks to verify the calling
environment of set_regs(). PROC_LOCK()/UNLOCK() around
the call to proc_write_regs() so that it's invariants
are satisfied.

This will allow GENERIC configurations to boot on small memory boxes, but
not require end users who want to use CTL to recompile their kernel. They
can simply set kern.cam.ctl.disable=0 in loader.conf.
The eventual solution to the memory usage problem is to change the way
CTL allocates memory to be more configurable, but this should fix things
for small memory situations in the mean time.
UPDATING: Explain the change in the CTL configuration, and
how users can enable CTL if they would like to use
it.
sys/conf/options: Add a new option, CTL_DISABLE, that prevents CTL
from initializing.
ctl.c: If CTL_DISABLE is turned on, don't initialize.
i386/conf/GENERIC,
amd64/conf/GENERIC: Re-enable device ctl, and add the CTL_DISABLE
option.
- Rewrite kevent() timeout implementation to allow sub-tick precision.
- Make the interval timings for EVFILT_TIMER more accurate. This also
removes an hack introduced in r238424.

kern_nanosleep() is now converted to use tsleep_sbt(). With this change
nanosleep() and usleep() can handle sub-tick precision for timeouts.
Also, try to help coalesce of events passing as argument to tsleep_bt()
a precision value calculated as a percentage of the sleep time.
This percentage is default 5%, but it can tuned according to users
need via the sysctl interface.

- Switch syscons from timeout() to callout_reset_flags() and specify that
precision is not important there -- anything from 20 to 30Hz will be fine.
- Reduce syscons "refresh" rate to 1-2Hz when console is in graphics mode
and there is nothing to do except some polling for keyboard. Text mode
refresh would also be nice to have adaptive, but this change at least
should help laptop users who running X.

As vm objects are type-stable there is no need to initialize the
resident splay tree pointer and the cache splay tree pointer in
_vm_object_allocate() but this could be done in the init UMA zone
handler.
The destructor UMA zone handler, will further check if the condition is
retained at every destruction and catch for bugs.
