MORITA Kazutaka 7cdb1f6d30 block: call the snapshot handlers of the protocol drivers
When snapshot handlers are not defined in the format driver, it is
better to call the ones of the protocol driver.  This enables us to
implement snapshot support in the protocol driver.

We need to call bdrv_close() and bdrv_open() handlers of the format
driver before and after bdrv_snapshot_goto() call of the protocol.  It is
because the contents of the block driver state may need to be changed
after loading vmstate.

MORITA Kazutaka 2bc93fed76 close all the block drivers before the qemu process exits
This patch calls the close handler of the block driver before the qemu
process exits.

This is necessary because the sheepdog block driver releases the lock
of VM images in the close handler.

Kevin Wolf 08a00559f0 block: Assume raw for drives without media
qemu -cdrom /dev/cdrom with an empty CD-ROM drive doesn't work any more because
we try to guess the format and when this fails (because there is no medium) we
exit with an error message.

This patch should restore the old behaviour by assuming raw format for such
drives.

Markus Armbruster 57dac7ef8a ide: Remove redundant IDEState member conf
Commit 428c149b added IDEState member conf to let commit 0009baf1 find
the BlockConf from there.  It exists only for qdev drives, created via
ide_drive_initfn(), not for drives created via ide_init2().

But for a qdev drive, we can just as well reach its IDEDevice, which
contains the BlockConf.  Do that, and revert the parts of commit
428c149b that add IDEState member conf.

Luiz Capitulino 637503d122 Monitor: Drop QMP documentation from code
Previous commit added QMP documentation to the qemu-monitor.hx
file, it's is a copy of this information.

While it's good to keep it near code, maintaining two copies of
the same information is too hard and has little benefit as we
don't expect client writers to consult the code to find how to
use a QMP command.

Jan Kiszka b40292e711 QMP: Introduce commands documentation
One of the most important missing feature in QMP today is its
supported commands documentation.

The plan is to make it part of self-description support, however
self-description is a big task we have been postponing for a
long time now and still don't know when it's going to be done.

In order not to compromise QMP adoption and make users' life easier,
this commit adds a simple text documentation which fully describes
all QMP supported commands.

This is not ideal for a number of reasons (harder to maintain,
text-only, etc) but does improve the current situation. To avoid at
least divering from the user monitor help and texi snippets, QMP bits
are also maintained inside qemu-monitor.hx, and hxtool is extended to
generate a single text file from them.
