block: Move initialisation of BlockLimits to bdrv_refresh_limits()

This function separates filling the BlockLimits from bdrv_open(), which
allows it to call it from other operations which may change the limits
(e.g. modifications to the backing file chain or bdrv_reopen)...

block: resize backing image during active layer commit, if needed

If the top image to commit is the active layer, and also larger than
the base image, then an I/O error will likely be returned during
block-commit.

For instance, if we have a base image with a virtual size 10G, and a...

libcurl versions 7.16.0 and later have a timer callback interface which

sheepdog: fix 'qemu-img map'

It was muted in the previous commit 4bc74be9. Let's revive it since nothing

drive mirror:fix memory leak

In the function mirror_iteration() > qemu_iovec_init(),
it allocates memory for op>qiov.iov, when the write request calls back,
but in the function mirror_iteration_done(), it only frees the op,
not free the op->qiov.iov, so this causes memory leak....
