linux-user build on fedora 11 breaks because fallocate
is broken on that system if -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64
are specified, which is what QEMU uses.
We do have a configure check to catch this and disable fallocate,
however, it turns out that default QEMU_CFLAGS/LDFLAGS were assigned in
script *after* all compiler checks: so during checks we were not running
compiler with same flags that we used for build later.
Fix this by moving QEMU_CFLAGS to before compiler checks, and using
comple_prog when checking for fallocate. This also fixes the fact that
we do some compiler checks while assigning the flags, right below a
comment that says "no cc tests beyond this point".

PCI spec states:
if a masked vector has its Pending bit set, and the associated
underlying interrupt events are somehow satisfied (usually by software
though the exact manner is function-specific), the function must clear
the Pending bit, to avoid sending a spurious interrupt message later
when software unmasks the vector.
In our case this happens if vector becomes unused.
Clear pending bit in this case.

On reset, we currently clear all bits in msix control register *except*
enable bit. This is wrong: the spec says we should clear writeable
bits: function mask and enable bit.
Correct this.

tcg: initial mips support
Based on a patch from Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org>
A few words about design choices:
* Two registers, at and t0, are reserved for TCG internal use. They are
useful for bswap and 64-bit ops.
* Most ops supports a constant argument with value 0, which is actually
mapped to the zero register.
* While the at register is available for constant loading, ops only
support a limited range of constants. TCG does a better job doing the
register allocation and constant loading by itself. There are plenty of
registers available anyway.

Revert "vga: do not resize the screen on hw_invalidate"
This causes ctrl+alt+u or ctrl+alt+f to not work when windows hasn't been
resized first. Other graphic emulators do resize the screen on
hw_invalidate.
Fix cpu_get_real_ticks:
- check should be done on __mips and not __mips_isa_rev
- linux kernels >= 2.6.25 are emulating the 2 needed rdhwr functions
so it's safe to use rdhwr.
This is better than what's currently in but it doesn't mean it works nicely
Some tests needs to be done imho

Convert linux bootrom to external rom and fw_cfg
We already have a working multiboot implementation that uses fw_cfg to get
its kernel module etc. data in int19 runtime now.
So what's missing is a working linux boot option rom. While at it I figured it
would be a good idea to take the opcode generator out of pc.c and instead use
a proper option rom, like we do with multiboot.
