[PULL 1/8] tests/vm: netbsd autoinstall, using serial console

[Alex Bennée]

From: Gerd Hoffmann <kraxel@redhat.com>

Instead of fetching the prebuilt image from patchew download the install
iso and prepare the image locally.  Install to disk, using the serial
console.  Create qemu user, configure ssh login.  Install packages
needed for qemu builds.

[PULL 5/8] tests: only run ipmi-bt-test if CONFIG_LINUX

[Alex Bennée]

This test has been unstable on NetBSD for awhile. It seems the
mechanism used to listen to a random port is a Linux-ism (although a
received wisdom Linux-ism rather than a well documented one). As
working around would add more hard to test complexity to the test I've
gone for the easier option of making it CONFIG_LINUX only.

[PULL 7/8] .travis.yml: don't run make check with multiple jobs

[Alex Bennée]

Let's challenge the convention that doing more at a time helps. It
certainly doesn't tell you unambiguously where in the test cycle you
were before the test hangs and exceeds the job time limit.

[PULL 8/8] tcg plugins: expose an API version concept

[Alex Bennée]

This is a very simple versioning API which allows the plugin
infrastructure to check the API a plugin was built against. We also
expose a min/cur API version to the plugin via the info block in case
it wants to avoid using old deprecated APIs in the future.

Applied, thanks.

Please update the changelog at https://wiki.qemu.org/ChangeLog/4.2
for any user-visible changes.

PS: just noticed, but shouldn't the plugin-version change
have needed an update to the docs ?

thanks
