block: add .bdrv_co_write_zeroes() interface

The ability to zero regions of an image file is a useful primitive for
higher-level features such as image streaming or zero write detection.

Image formats may support an optimized metadata representation instead
of writing zeroes into the image file.  This allows zero writes to be
potentially faster than regular write operations and also preserve
sparseness of the image file.

The .bdrv_co_write_zeroes() interface should be implemented by block
drivers that wish to provide efficient zeroing.

Note that this operation is different from the discard operation, which
may leave the contents of the region indeterminate.  That means
discarded blocks are not guaranteed to contain zeroes and may contain
junk data instead.

cutils: extract buffer_is_zero() from qemu-img.c

The qemu-img.c:is_not_zero() function checks if a buffer contains all
zeroes.  This function will come in handy for zero-detection in the
block layer, so clean it up and move it to cutils.c.

Note that the function now returns true if the buffer is all zeroes.
This avoids the double-negatives (i.e. !is_not_zero()) that the old
function can cause in callers.

w32: Fix build with new net bridge code

Commit a7c36ee4920ea3acc227a0248dd161693f207357 added code for a net
bridge and explicitly said that "this is very Linux centric".

Indeed, compilation failed for w32, so the bridge code is now
conditional. Hosts which don't support it can simply remove the
definition of CONFIG_NET_BRIDGE.

object: sure up reference counting

Now we have the following behavior:

1) object_new() returns an object with ref = 1
2) object_initialize() does not increase the reference count (ref may be 0).
3) object_deref() will finalize the object when ref = 0.  it does not free the
   memory associated with the object.
4) both link and child properties correctly set the reference count.

The expected usage is the following:

1) child devices should generally be created via object_initialize() using
   memory from the parent device.  Adding the object as a child property will
   take ownership of the object and tie the child's life cycle to the parent.

2) If a child device is created via qdev_create() or some other form of
   object_new(), there must be an object_delete() call in the parent device's

linux-user: fake /proc/self/maps

glibc's pthread_attr_getstack tries to find the stack range from
/proc/self/maps. Unfortunately, /proc is usually the host's /proc

linux-user: save auxv length

We create our own AUXV segment on stack and save a pointer to it.
However we don't save the length of it, so any code that wants to
do anything useful with it later on has to walk it again.

Instead, let's remember the length of our AUXV segment. This

When running Linux on e500 with powersave-nap enabled, Linux tries to
read out the L1CFG0 register and calculates some things from it. Passing
0 there ends up in a division by 0, resulting in -1, resulting in badness.
