Currently we use the "Virtualization Tools" product in Red Hat Bugzilla
for issue tracking upstream. This changes to point people to GitLab for
issue tracking.
Note that Bugzilla still has plenty of bugs present against libvirt.
Triaging these to determine what is still valid will be a separate
exercise. Bugzilla will be locked to prevent creation of new issues
meanwhile.

The libvirt project has alot of git repositories, and they must all be
configured in the same way, more or less. This page documents the
settings changes that I have made in GitLab and GitHub when configuring
projects, both as a reminder for myself, and to help anyone else doing
the same in future. Also included is info about the repo mirroring on
the libvirt.org server.

To encourage contributors to make changes to the main website, add a
footer link to every page which links to the corresponding source file
in git. With gitlab, they are able to edit content directly in the web
browser and then submit a merge request. This gives a way to contribute
content that is arguably easier than our wiki which requires manual
account creation, while this will also benefit from maintainer review.

The signatures of these two CPU model differ only in stepping as both
report family 6 and model 85. Skylake-Server uses stepping 4 or less and
Cascadelake-Server uses stepping 5..7.

CPU models defined in the cpu_map can use signature/@stepping attribute
to match a limited set of stepping numbers. The value is a bitmap for
bits 0..15 each corresponding to a single stepping value. For example,
stepping='4-6,9' will match 4, 5, 6, and 9. Omitting the attribute is
equivalent to stepping='0-15'.

The hint was introduced a long time ago when broken TSX implementation
was found in Haswell and Broadwell CPUs. Since then many more CPUs with
TSX were introduced and and disabled due to TAA vulnerability.
Thus the hint is not very useful and I think removing it is a better
choice then updating it to cover all current noTSX models.
This partially reverts:

Unlike `waitpid`, `virProcessWait` only returns -1 (error) or 0
(success), so comparing that to `pid` will always be false and the
parent will report failure with:
error : main:851 : Failed to fork as daemon: No such file or directory
even though the grandchild process is succesfully running. Note that the
errno message is misleading: it was last set when trying to find a
restart state file.
