- Move group task queue into kern/subr_gtaskqueue.c
- Change intr_enable to return an int so it can be detected if it's not
implemented
- Allow different TX/RX queues per set to be different sizes
- Don't split up TX mbufs before transmit
- Allow a completion queue for TX as well as RX
- Pass the RX budget to isc_rxd_available() to allow an earlier return
and avoid multiple calls

Some defines needed for exporting serial numbers from the SMBIOS were
missed during integration of SMBIOS support in the EFI boot loader (r281138).
This is needed for getting the hostid set from the system hardware UUID.

These may have ccache in them or -target/--sysroot from external
compiler or SYSTEM_COMPILER support. Many ports do not support
a CC with spaces in it, such as emulators/virtualbox-ose-kmod.
Passing --sysroot to ports makes no sense as ports doesn't support
--sysroot currently.
If these variables need to be overridden for ports then they can
be set in make.conf or passed as make arguments.

promote memory as I am not sure all the demotion cases are handled, however
it is useful to implement pmap_page_set_memattr. This is used, for example,
when mapping uncached memory for bus_dma(9).
pmap_page_set_memattr needs to demote the DMAP region as on ARM we need to
ensure all mappings to the same physical address have the same attributes.

CloudABI executables already provide support for passing in vDSOs. This
functionality is used by the emulator for OS X to inject system call
handlers. On FreeBSD, we could use it to optimize calls to
gettimeofday(), etc.
Though I don't have any plans to optimize any system calls right now,
let's go ahead and already pass in a vDSO. This will allow us to
simplify the executables, as the traditional "syscall" shims can be
removed entirely. It also means that we gain more flexibility with
regards to adding and removing system calls.

On all the other architectures, this function can also be called on the

Machine privilege level was specially designed to use in vendor's
firmware or bootloader. We have implemented operation in machine
mode in FreeBSD as part of understanding RISC-V ISA, but it is time
to remove it.
We now use BBL (Berkeley Boot Loader) -- standard RISC-V firmware,
which provides operation in machine mode for us.
We now use standard SBI calls to machine mode, instead of handmade
'syscalls'.
o Remove HTIF bus.
HTIF bus is now legacy and no longer exists in RISC-V specification.
HTIF code still exists in Spike simulator, but BBL do not provide
raw interface to it.
Memory disk is only choice for now to have multiuser booted in Spike,
until Spike has implemented more devices (e.g. Virtio, etc).

Previously the loop in PCIIOCGETCONF would terminate as soon as it
found enough matches. Now it will continue iterating through the
PCI device list and only terminate if it finds another matching device
for which it has no room to store a conf structure. This means that
PCI_GETCONF_LAST_DEVICE is reliably returned when the number of
matching devices is equal to the number of slots in the matches
buffer. For example, if a program requests the conf structure for a
single PCI function with a specified domain/bus/slot/function it will
now get PCI_GETCONF_LAST_DEVICE instead of PCI_GETCONF_MORE_DEVS.
While here, simplify the loop conditional a bit more by explicitly
breaking out of the loop if copyout() fails and removing a redundant
i < pci_numdevs check.
