- Group the output so that it follows the capability register set more
closely. The first line now contains device information and the
second line contains link information. As a result, ARI status is now
output on the first line, and the link width is moved down to the second
line of link information.
- Only read the DEVICE_CAP2 register to check for ARI if the capability
version is >= 2.
- Don't output any link information if the link capability and status
registers are zero.
- Label the MSI interrupt index value as "MSI" instead of "IRQ".

The i8254 simulation in Hyper-V is kinda broken and is not available
in Generation 2 Hyper-V VMs, so Hyper-V timer must be registered early
enough so that it can be used to do the TSC freq calibration.

The large read test uses an empty file created via mkstemp() rather than
/dev/null as character devices are subject to two different clamping
sysctls. However, I forgot to update some of the error messages after
changing to mkstemp() that were still referring to /dev/null.
- Set BI_CAN_EXEC_DYN, so we can execute ET_DYN ELF files in addition to
regular ET_EXECs.
- Provide an AT_BASE entry in the auxiliary vector, so the executable
knows at which address it got loaded and can apply relocations.
Some time ago I made a change to merge together the memory scope
definitions used by mmap (MAP_{PRIVATE,SHARED}) and lock objects
(PTHREAD_PROCESS_{PRIVATE,SHARED}). Though that sounded pretty smart
back then, it's backfiring. In the case of mmap it's used with other
flags in a bitmask, but for locking it's an enumeration. As our plan is
to automatically generate bindings for other languages, that looks a bit
sloppy.
Change all of the locking functions to use separate flags instead.

Previously, calls to *sleep() and cv_*wait*() immediately returned during
early boot. Instead, permit threads that request a sleep without a
timeout to sleep as wakeup() works during early boot. Sleeps with
timeouts are harder to emulate without working timers, so just punt and
panic explicitly if any thread tries to use those before timers are
working. Any threads that depend on timeouts should either wait until
SI_SUB_KICK_SCHEDULER to start or they should use DELAY() until timers
are available.
Until APs are started earlier this should be a no-op as other kthreads
shouldn't get a chance to start running until after timers are working
regardless of when they were created.

nic->num_vf_en is set based on the number of the enabled LMACs.
This number should not be overwritten later by any routine.
Instead it should fail PCI_IOV_ADD_VF() so that available VFs
with the corresponding LMACs will attach whereas other, disabled
VFs will fail with the proper error code.
Error signaling (due to improper number of VFs requested) is also moved
from PCI_IOV_INIT() to PCI_IOV_ADD_VF().
This will be reworked when multiple queue sets are enabled but for
now this is the correct behavior of the driver.
