qemu.org enabled HTTPS in 2017 and it should be used instead of HTTP.
There are also URLs to json.org, openvpn.net, and other domains that
support HTTPS.
This patch updates the qemu.org domains everywhere and also third-party
domains that I have checked.

The owner of qemu.org has delegated authority to modify DNS records to
the QEMU Project. This has allowed us to use the domain name without
worries about IP address changes or technical issues disrupting service.
The issues described in commit 8593898109
("Use qemu-project.org domain name") have therefore been mitigated.
This patch switches back to consistently using qemu.org instead of
qemu-project.org in documentation, version.rc, and the Windows installer
script.
The git submodules and SeaBIOS still use qemu-project.org for the time
being. This will be fixed in the QEMU 2.12 release cycle.

Introduce a privileged helper to run persistent reservation commands.
This lets virtual machines send persistent reservations without using
CAP_SYS_RAWIO or out-of-tree patches. The helper uses Unix permissions
and SCM_RIGHTS to restrict access to processes that can access its socket
and prove that they have an open file descriptor for a raw SCSI device.
The next patch will also correct the usage of persistent reservations
with multipath devices.
It would also be possible to support for Linux's IOC_PR_* ioctls in
the future, to support NVMe devices. For now, however, only SCSI is
supported.

Currently, vhost-user does not implement any means for notifying the
backend about guest endianess. This commit introduces a new message
called VHOST_USER_SET_VRING_ENDIAN which is analogous to the ioctl()
called VHOST_SET_VRING_ENDIAN used for kernel vhost backends. Such
message is necessary for backends supporting legacy (pre-1.0) virtio
devices running in big-endian guests.

This patch documents (including their QMP invocations) all the four
major kinds of live block operations:
- `block-stream`
- `block-commit`
- `drive-mirror` (& `blockdev-mirror`)
- `drive-backup` (& `blockdev-backup`)
Things considered while writing this document:
- Use reStructuredText as markup language (with the goal of generating
the HTML output using the Sphinx Documentation Generator). It is
gentler on the eye, and can be trivially converted to different
formats. (Another reason: upstream QEMU is considering to switch to
Sphinx, which uses reStructuredText as its markup language.)
- Raw QMP JSON output vs. 'qmp-shell'. I debated with myself whether
to only show raw QMP JSON output (as that is the canonical
representation), or use 'qmp-shell', which takes key-value pairs. I
settled on the approach of: for the first occurrence of a command,
use raw JSON; for subsequent occurrences, use 'qmp-shell', with an
occasional exception.
- Usage of `-blockdev` command-line.
- Usage of 'node-name' vs. file path to refer to disks. While we have
`blockdev-{mirror, backup}` as 'node-name'-alternatives for
`drive-{mirror, backup}`, the `block-commit` command still operates
on file names for parameters 'base' and 'top'. So I added a caveat
at the beginning to that effect.
Refer this related thread that I started (where I learnt
`block-stream` was recently reworked to accept 'node-name' for 'top'
and 'base' parameters):
https://lists.nongnu.org/archive/html/qemu-devel/2017-05/msg06466.html
"[RFC] Making 'block-stream', and 'block-commit' accept node-name"
All commands showed in this document were tested while documenting.
Thanks: Eric Blake for the section: "A note on points-in-time vs file
names". This useful bit was originally articulated by Eric in his
KVMForum 2015 presentation, so I included that specific bit in this
document.

This is part of the on-going effort to convert QEMU upstream
documentation syntax to reStructuredText (rST).
The conversion to rST was done using:
$ pandoc -f markdown -t rst bitmaps.md -o bitmaps.rst
Then, make a couple of small syntactical adjustments. While at it,
reword a statement to avoid ambiguity. Addressing the feedback from
this thread:

A bitmap directory entry is sometimes called a 'bitmap header'. This
patch leaves only one name - 'bitmap directory entry'. The name 'bitmap
header' creates misunderstandings with 'qcow2 header' and 'qcow2 bitmap
header extension' (which is extension of qcow2 header)
