Add proper -errno error return values to qcow2_open()

In addition this adds missing braces to the function to be consistent
with the coding style.

block/qcow2.c: rename qcow_ functions to qcow2_

It doesn't really make sense for functions in qcow2.c to be named
qcow_ so convert the names to match correctly.

qed: Table, L2 cache, and cluster functions

This patch adds code to look up data cluster offsets in the image via
the L1/L2 tables. The L2 tables are writethrough cached in memory for
performance (each read/write requires a lookup so it is essential to
cache the tables)....

qed: Read/write support

This patch implements the read/write state machine. Operations are
fully asynchronous and multiple operations may be active at any time.

Allocating writes lock tables to ensure metadata updates do not
interfere with each other. If two allocating writes need to update the...

qed: Consistency check support

This patch adds support for the qemu-img check command. It also
introduces a dirty bit in the qed header to mark modified images as
needing a check. This bit is cleared when the image file is closed

If an image file is opened and it has the dirty bit set, a consistency...

block: add discard support

Add a new bdrv_discard method to free blocks in a mapping image, and a new
drive property to set the granularity for these discard. If no discard
granularity support is set discard support is disabled.

raw-posix: add discard support

Add support to discard blocks in a raw image residing on an XFS filesystem
by calling the XFS_IOC_UNRESVSP64 ioctl to punch holes. Support for other
hole punching mechanisms can be added when they become available.
