When using GNULIB with Winsock, libvirt will never see the normal HANDLE
objects, instead GNULIB guarantees that libvirt gets a C runtime file
descriptor. The GNULIB poll impl also expects to get C runtime file
descriptors rather than HANDLE objects. Document this behaviour so that
it is clear to applications providing event loop implementations if they
need Windows portability.

Ideally we would test macOS 10.15 as the newest release, however, that
is not available in Travis yet. We can at least test newer XCode
versions though to get toolchain validation.

We initially claimed to only support the most recent macOS
release, which is currently 10.15. Our Travis CI, however,
is validating 10.14.4 / XCode 10.3.
For almost all of our other platforms, we support multiple
releases to some degree. This change brings macOS in line
with other long life distros, covering the most recent &
most recent but one for a 2 year overlap. With this docs
change our CI is now actually testing our minimum version.

We have a strong check for GCC >= 4.8, but don't validate any
version number for CLang historically.
This defines the min CLang to be 3.4 which is what is available
for RHEL-7. macOS uses a different versioning scheme for CLang,
based off XCode versions. There is a mapping recorded at
https://en.wikipedia.org/wiki/Xcode#Toolchain_versions
Here we see upstream CLang 3.4 corresponds to XCode 5.1
XCode 5.1 is available for macOS 10.8.4 or later which
trivially satisfies our platform support matrix requirements.
All these versions match what QEMU declares for its min GCC
and CLang checks.

The Python3 package has started failing to install from
HomeBrew with the following:
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink Frameworks/Python.framework/Headers
Target /usr/local/Frameworks/Python.framework/Headers
is a symlink belonging to python@2. You can unlink it:
brew unlink python@2
To force the link and overwrite all conflicting files:
brew link --overwrite python
The result is that libvirt fails to find python3:
checking for python3... no
configure: error: 'python3' binary is required to build libvirt
It is unclear what changed in Travis/HomeBrew to break our
previously working setup, but running the suggested command
fixes it well enough for libvirt's CI needs.

While command line arguments are sort of positional (because you
have to have two entries, one for "-arg" the other for "value"),
it doesn't really matter whether env variables come before or

If we use fake reboot then domain goes thru running->shutdown->running
state changes with shutdown state only for short period of time. At
least this is implementation details leaking into API. And also there is
one real case when this is not convinient. I'm doing a backup with the
help of temporary block snapshot (with the help of qemu's API which is
used in the newly created libvirt's backup API). If guest is shutdowned
I want to continue to backup so I don't kill the process and domain is
in shutdown state. Later when backup is finished I want to destroy qemu
process. So I check if it is in shutdowned state and destroy it if it
is. Now if instead of shutdown domain got fake reboot then I can destroy
process in the middle of fake reboot process.
After shutdown event we also get stop event and now as domain state is
running it will be transitioned to paused state and back to running
later. Though this is not critical for the described case I guess it is
better not to leak these details to user too. So let's leave domain in
running state on stop event if fake reboot is in process.
Reconnection code handles this patch without modification. It detects
that qemu is not running due to shutdown and then calls qemuProcessShutdownOrReboot
which reboots as fake reboot flag is set.

Mind that virfirewall.c was not touched and still contains no_memory

the conversion seems to be slightly more complicated than the rest, as
