Intel Multiprocessor Specification v1.4. The Intel SDM claims that
the INIT IPIs here are invalid, but other systems follow the MP
spec instead.
While here, fix the IPI wait routine to accept a timeout in microseconds
instead of a raw spin count, and don't spin forever during AP startup.
Instead, panic if a STARTUP IPI is not delivered after 20 us.

This change allows multiple "portal-group" options to be specified per
target. Each of them may include new optional auth-group name parameter
to override per-target auth parameters for specific portal group.

particular, updates to the watchdog should no longer sleep.
- Add a new IPMI_IO_LOCK for low-level I/O access. Use this for
kcs_polled_request() and smic_polled_request().
- Add a new backend callback "ipmi_driver_request" to handle a driver
request. The new callback performs the request sychronously for KCS
and SMIC. SSIF still defers the work to the worker thread since the
worker thread sleeps during request processing anyway.
- Allocate driver requests on the stack rather than using malloc().

allows the user to request administrative changes to individual devices
such as attach or detaching drivers or disabling and re-enabling devices.
- Add a new /dev/devctl2 character device which uses ioctls for device
requests. The ioctls use a common 'struct devreq' which is somewhat
similar to 'struct ifreq'.
- The ioctls identify the device to operate on via a string. This
string can either by the device's name, or it can be a bus-specific
address. (For unattached devices, a bus address is the only way to
locate a device.) Bus drivers register an eventhandler to claim
unrecognized device names that the driver recognizes as a valid address.
Two buses currently support addresses: ACPI recognizes any device
in the ACPI namespace via its full path starting with "\" and
the PCI bus driver recognizes an address specification of
'pci[<domain>:]<bus>:<slot>:<func>' (identical to the PCI selector
strings supported by pciconf).
- To make it easier to cut and paste, change the PnP location string
in the PCI bus driver to output a full PCI selector string rather
than 'slot=<slot> function=<func>'.
- Add a devctl(3) interface in libdevctl which provides a wrapper around
the ioctls and is the preferred interface for other userland code.
- Add a devctl(8) program which is a simple wrapper around the requests
supported by devctl(3).
- Add a device_is_suspended() function to check DF_SUSPENDED.
- Add a resource_unset_value() function that can be used to remove a
hint from the kernel environment. This is used to clear a
hint.<driver>.<unit>.disabled hint when re-enabling a boot-time
disabled device.

This was a local addition to the original change from NetBSD.
Being this libc there is some chance for it to interfere with

I discovered this while working on llvm/lld and realized export-dynamic

both - and --, switch this in our build system, because GNU ld supports
both modes, and because there's some hope lld will become the default linker
for FreeBSD in the future.
