Introduce the functions needed to change the backing file of an image. The

If an image references a backing file that doesn't exist, qemu-img info fails
to open this image. Exactly in this case the info would be valuable, though:
the user might want to find out which file is missing.

This patch introduces a BDRV_O_NO_BACKING flag to ignore the backing file when
opening the image. qemu-img info is the first user and provides info now even
if the backing file is invalid.

After the next commit, pkg-config could be used for the shared library
configuration case and sdl-config for static libraries.  So I prepare
the test here by doing two changes:

at the same time I remove useless backslashes from the invocation of
grep;

1) fixing a typo ($sd_cflags).  The typo has been there since commit
1ac88f28 (remove sdl_static. Just do the right thing if static is yes,
2009-07-27).

2) fixing an erroneous "test `... | grep > /dev/null`" idiom that would
never succeed since grep's output would be empty;

3) checking the status code after executing sdl-config --static --libs;
this is needed for the next patch only.

Use new way to associate ROM files to devices.

Currently, there is only a ROM file for i82559er
included in QEMU, so the patch does not add
.romfile for the other devices.

When flexible mode is fixed in eepro100, adding
more ROM files will be possible. It should be
possible to create them from pxe-i82559er.bin,
because etherboot uses the same driver for all
eepro100 devices (only PCI ids differ).

Maybe it is even possible to create a single
pxe-i8255x.bin which supports all eepro100 devices
(not supported with current etherboot).

the ioctl doesn't actually work yet (except in the Linuxolator), so if

The {div,divu}2 opcodes are intended for systems for which the
division instruction produces both quotient and remainder.  Sparc
is not such a system.  Indeed, the remainder must be computed as

  quot = a / b
  rem = a - (quot * b)

Split out a tcg_out_div32 function that properly initializes Y
with the extension of the input to 64-bits.  Discard the code
that used the 64-bit DIVX on sparc9/sparcv8plus without extending
the inputs to 64-bits.  Implement remainders in terms of division
followed by multiplication.

Hi all,
calling vnc_update_client in vnc_refresh might have the unlikely side
effect of setting vd->timer = NULL, if the last vnc client disconnected.
In this case we have to return from vnc_refresh without updating the
