Remove NULL checks for bdrv_new return value

It's an indirect call to qemu_malloc, which never returns an error.

use qemu_blockalign consistently

Use qemu_blockalign for all allocations in the block layer. This allows
increasing the required alignment, which is need to support O_DIRECT on
devices with large block sizes.

nbd: Introduce NBD named exports.

This patch allows to connect Qemu using NBD protocol to an nbd-server
using named exports.

For instance, if on the host "isoserver", in /etc/nbd-server/config, you have:

qemu-nbd: Improve error reporting

- use err(3) instead of errx(3) if errno is available
to report why failed
- let fail prior to daemon(3) if opening a nbd file
is likely to fail after daemonizing to avoid silent
failure exit
- add missing 'ret = 1' when unix_socket_outgoing failed...

Replace calls of old bdrv_open

What is known today as bdrv_open2 becomes the new bdrv_open. All remaining
callers of the old function are converted to the new one. In some places they
even know the right format, so they should have used bdrv_open2 from the...

qemu-nbd: Fix invalid usage of the first argument of errx

errx takes the exit status of a process as the first
argument. Passing errno to it is wrong. Instead the
patch lets errx take EXIT_FAILURE.

win32: pair qemu_memalign() with qemu_vfree()

Win32 suffers from a very big memory leak when dealing with SCSI devices.
Each read/write request allocates memory with qemu_memalign (ie
VirtualAlloc) but frees it with qemu_free (ie free).
Pair all qemu_memalign() calls with qemu_vfree() to prevent such leaks....

Instead of using the field 'readonly' of the BlockDriverState struct for passing the request,...
