3e7db8d3e8 Remove backslash alignment attempts
Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

cea3715b2e QoS: Set classes and filters in proper direction
Similarly to previous patch, for some types of interface domain
and host are on the same side of RX/TX barrier. In that case, we
need to set up the QoS differently. Well, swapped.

4ceac4bf29 tests: Rename VIRT_TEST_* macros to VIR_TEST_*
We use the "vir" prefix pretty consistently in our
APIs, both external and internal, which made these
macros stood out.

065054daa7 virnetdevbandwidth: Compute quantum value
I've noticed couple of warning in dmesg while debugging
something:

[ 9683.973754] HTB: quantum of class 10001 is big. Consider r2q change.
[ 9683.976460] HTB: quantum of class 10002 is big. Consider r2q change.

I've read the HTB documentation and linux kernel code to find out
what's wrong. Basically we need to pass another argument
"quantum" to our tc cmd line because the default computed by HTB
does not always work in which case the warning message is printed
out.

2397be694d virNetDevBandwidthSet: Add priority to filter
Currently, when constructing traffic shaping rules, the ingress
filter is created without any priority specified on the command
line. This makes kernel to make up one. While this works, it
simplifies things a bit if we provide the filter priority. In
this case, since it's the root filter lets give it the highest
priority of number 1.

a605025c21 conf: Increase virNetDevBandwidthParse intelligence
There's this function virNetDevBandwidthParse which parses the
bandwidth XML snippet. But it's not clever much. For the
following XML it allocates the virNetDevBandwidth structure even
though it's completely empty:

    <bandwidth>
    </bandwidth>

Later in the code there are some places where we check if
bandwidth was set or not. And since we obtained pointer from the
parsing function we think that it is when in fact it isn't.

9a8fc3efc2 Iface: disallow network tuning in session mode globally
Patch 43b67f2e disallowed network tuning only with qemu driver, however
this patch moved the check for root privileges into
virNetDevBandwidthSet function, so the call should now
fail in all possible cases. A mock function was created so that the test
suite doesn't fail because of unsufficient privileges.

d9de144385 QoS: make tc filters match all traffic
Up until now the traffic control filters for the vNIC QoS were
matching only ip traffic. For egress traffic that was unnoticed
because the unmatched traffic would just go to the default htb class
and be shaped anyway. For ingress, though, since the policing of the
rate is done by the filter itself.

The problem is solved by changing protocol to all and making anything
match the filter.

7b3f1f8c30 Add ability to register callback for virCommand dry run
To allow for fault injection of the virCommand dry run,
add the ability to register a callback. The callback will
be passed the argv, env and stdin buffer and is expected
to return the exit status and optionally fill stdout and
stderr buffers.

e60b36cb0d virnetdevbandwidthtest: Introduce some more tests
And while doing this, fix one error raised by coverity. With
current code, @actual_cmd is allowed to be NULL for the whole
run of testVirNetDevBandwidthSet. However, if something else
was expected, the @actal_cmd is passed to virtTestDifference
which dereference it immediately.

122cd16982 Revert "networkAllocateActualDevice: Set QoS for bridgeless networks too"
This reverts commit 2996e6be19
and some parts of 2636dc8c4d.

The former one tried to implement QoS setting on bridgeless networks.
However, as discussed upstream [1], the patch is far away from being
useful in even a single case. The whole idea of network QoS is to have
aggregated limits over several interfaces. This patch is doing
completely the opposite when merging two QoS settings (from the network
and the domain interface) into one which is then set at the domain
interface itself, not the network.

The latter one is the test for the previous one. Now none of them makes
sense.
