vfio-pci: Generalize PCI config mangling

Kernel-side vfio virtualizes all of config space, but some parts are
unique to Qemu.  For instance we may or may not expose the ROM BAR,
Qemu manages MSI/MSIX, and Qemu manages the multi-function bit so that
single function devices can appear as multi-function and vica versa.
Generalize this into a bitmap of Qemu emulated bits.

vfio-pci: Add PCIe capability mangling based on bus type

Windows seems to pay particular interest to the PCIe header type of
devices and will fail to load drivers if we attach Endpoint devices or
Legacy Endpoint devices to the Root Complex.  We can use
pci_bus_is_express and pci_bus_is_root to determine the bus type and
mangle the type appropriately:

* Legacy PCI
  * No change, capability is unmodified for compatibility.
* PCI Express
  * Integrated Root Complex Endpoint -> Endpoint
* PCI Express Root Complex
  * Endpoint -> Integrated Root Complex Endpoint
  * Legacy Endpoint -> none, capability hidden

We also take this opportunity to explicitly limit supported devices
to Endpoints, Legacy Endpoints, and Root Complex Integrated Endpoints.
We don't currently have support for other types and users often cause
themselves problems by assigning them.

qemu vfio-pci: Add support for VGA MMIO and I/O port access

Most VGA cards need some kind of quirk to fully operate since they
hide backdoors to get to other registers outside of PCI config space
within the registers, but this provides the base infrastructure.  If
we could identity map PCI resources for assigned devices we would need
a lot fewer quirks.

To enable this, use a kernel side vfio-pci driver that incorporates
VGA support (v3.9), and use the -vga none option and add the x-vga=on
option for the vfio-pci device.  The "x-" denotes this as an
experimental feature.  You may also need to use a cached copy of the
VGA BIOS for your device, passing it to vfio-pci using the romfile=
option.

qemu vfio-pci: Graphics device quirks

Graphics cards have a number of different backdoors.  Some of these
are alternative ways to get PCI BAR addresses, some of them are
complete mirrors of PCI config space available through MMIO and
I/O port access.  These quirks cover a number of ATI Radeon and
Nvidia devices.  On the ATI/AMD side, this should enable HD5450
and HD7850 and hopefully a host of devices around those generations.
For Nvidia, my card selection is much more dated.  A 8400gs works
well with both the Window shipped driver and the Nvidia downloaded
driver.  A 7300le works as well, with the caveat that generating
the Window experience index with the Nvidia driver causes the card
to reset several times before generating a BSOD.  An NVS 290 card
seems to run well with the shipped Windows driver, but generates
a BSOD with the Nvidia driver.  All of the Nvidia devices work with
the Linux Nvidia proprietary driver and nouveau, the HD5450 works
with either radeon or fglrx, HD7850 works with vesa and fglrx (not
supported by radeon).  Extremely limited 3D testing.

Device reset is also an issue with graphics.  It's unfortunately
very common that the devices offer no means to reset the card or
doesn't seem effective.  Nvidia devices are pretty good about being
able to get the device to a working state through the VGA BIOS init,
Radeon devices less so, and often require a host reboot.  Work
remains to be done here.

vfio-pci: Add extra debugging

Often when debugging it's useful to be able to disable bypass paths
so no interactions with the device are missed.  Add some extra debug
options to do this.  Also add device info on read/write BAR accesses,
which is useful when debugging more than one assigned device.  A
couple DPRINTFs also had redundant "vfio:" prefixes.

qemu-char: rewrite io_channel_send_all and drop the '_all' suffix

The current code is oddly written and have equally odd semantics.
Despite the '_all' suffix, upon EAGAIN the result will be a partial
write but instead of returning the partial write, we return EAGAIN.

Change the behavior to write as much as we can until we get an EAGAIN
returning a partial write if we do.
