Clean up some obsolete code in pci_virtio_net.c
Allow an error return from a PCI device emulation's init routine
to be propagated all the way back to the top-level and result in
the process exiting.

Gripe if the emulation is not recognized instead of silently ignoring the
emulated device.
If an error is detected by pci_parse_slot() then exit from the command line
parsing loop in main().

devices are MSI-X capable. This in turn would lead it to treat bar 0 as
the MSI-X table bar even if the underlying device did not support MSI-X.
Fix this by providing an API to query the MSI-X table index of the emulated
device. If the underlying device does not support MSI-X then this API will
return -1.

The current behavior of advertising a single MSI vector can be requested by
setting the environment variable "BHYVE_USE_MSI" to "true". The use of MSI
is not compliant with the virtio specification and will be eventually phased
out.

the maximum of 2048 allowed by the PCI specification.
Reuse macros from pcireg.h to interpret the MSI-X capability instead of rolling
our own.

Firmware tables require too much knowledge of system configuration,
and it's difficult to pass that information in general terms to a library.
The upcoming ACPI work exposed this - it will also livein bhyve.
Also, remove code specific to NetApp from the mptable name, and remove
the -n option from bhyve.

with a last-found per-vCPU cache to deal with the common case
of repeated guest accesses to MMIO registers in the same page.

be activated as part of the slot config options.
The syntax is:
-s <slotnum>,uart[,stdio]
The stdio parameter instructs the code to perform i/o using
stdin/stdout. It can only be used for one instance.
To allow legacy i/o ports/irqs to be used, a new variant of
the slot command, -S, is introduced. When used to specify a
slot, the device will use legacy resources if it supports
them; otherwise it will be treated the same as the '-s' option.
Specifying the -S option with the uart will first use the 0x3f8/irq 4
config, and the second -S will use 0x2F8/irq 3.
Interrupt delivery is awaiting the arrival of the i/o apic code,
but this works fine in uart(4)'s polled mode.
This code was written by Cynthia Lu @ MIT while an intern at NetApp,
with further work from neel@ and grehan@.
