The page 108 of the SPARC Version 8 Architecture Manual describes
that addcc and addxcc shall compute carry flag the same way.
The page 110 claims the same about subcc and subxcc instructions.
This patch fixes carry computation in corner cases and removes redundant code.
The most visible effect of the patch is enabling Solaris boot when using OBP.

You would only see this error on a fresh clone when srcdir == objdir.  configure
will fail because roms/pcbios doesn't exist.

git submodule integration doesn't cleanup very well when switching between
branches so you'll get an roms/pcbios directory from normal operations if you
switch between old branches.

Thanks to a mistake in configure, if you build outside of srcdir, you'll also
get a valid roms/pcbios.

      Unbreak tap compilation on OS X

Currently compiling the tap sources breaks on Mac OS X. This is because of:

  1) tap-linux.h requiring Linux includes
  2) typos
  3) missing #includes

This patch adds what's necessary to compile tap happily on Mac OS X.
I haven't tested if using tap actually works, but I don't think that's a
major issue as that code was probably seriously untested before already.

I didn't split the patch, because it's only a few lines of code and
splitting is probably not worth the effort here.

Fixes a couple of issues with msix table access:
- With misbehaving guests, misaligned 4 byte access could overflow
  msix table and cause qemu to segfault. Since PCI spec requires
  host to only issue dword-aligned accesses, as a fix,
  it's enough to mask the address low bits.
- Tables use pci format, not native format, and so
  we must use pci_[sg]et_long on read/write.

The context parameter in paio_submit isn't used anyway, so there is no reason
why block drivers should need to remember it. This also avoids passing a Linux
AIO context to paio_submit (which doesn't do any harm as long as the parameter
is unused, but it is highly confusing).

Changes:

 * We don't create/delete devices, we attach/detach them instead.
 * The separate autofilter list is gone, we simply walk the list
   of devices directly instead.
 * Autofiltering is done unconditionally now.  Non-auto device scan
   code got dropped.
 * Autofiltering turns off the timer if there is nothing to do, it
   runs only in case there are unattached host devices.

This patchs adds infrastructure to handle -usbdevice via qdev callbacks.
USBDeviceInfo gets a name field (for the -usbdevice driver name) and a
callback for -usbdevice parameter parsing.

The new usbdevice_create() function walks the qdev driver list and looks
for a usb driver with a matching name.  When a parameter parsing
callback is present it is called, otherwise the device is created via
usb_create_simple().

The rom_add_vga() and rom_add_option() macros are transformed into
functions.  They look at the new rom_enable_driver_roms variable
and only do something if it is set to non-zero, making vga+option rom
loading runtime option.  pc_init() sets rom_enable_driver_roms to 1.

With this in place we can move the rom loading calls from pc.c to the
individual drivers.
