54814c87f3 docs: Fix template matching in page.xsl
Our last default template had a match of "node()" which incidentally matched
everything, including text nodes.  Since this has the same priority according to
the XSLT spec, section 5.5:

  https://www.w3.org/TR/1999/REC-xslt-19991116#conflict

this is an error.  Also according to the same spec section, the XSLT processor
may signal the error or pick the last rule.

This was uncovered with libxslt 1.1.35 which contains the following commit:

  b0074eeca3

which makes the build fail with:

  runtime error: file ../docs/page.xsl line 223 element element
  xsl:element: The effective name '' is not a valid QName.

because our last rule also matches text nodes and we are trying to extract the
node name out of them.

To fix this we change the match to "*" which only matches elements and not all
the nodes, and to avoid any possible errors with different XSLT processors we
also bump the priority of the match="text()" rule a little higher, just in case
someone needs to use an XSLT processor that chooses signalling the error instead
of the optional recovery.

4c69d64efa meson: Explicitly specify run_command's check parameter
An update to meson 0.61.1 meant that it started showing warnings due to the fact
that the default for run_command's 'check' parameter is going to change.  It
unveiled the fact that we were even missing that parameter in some calls where
we expected different outcome.  To make sure the behaviour does not change
specify the parameter explicitly.  In places where we check for the return code
the parameter should be 'false' so that meson does not fail.  In all other cases
the parameter should be set to 'true' to make sure possible failure also stops
meson.

The warning in meson was added in https://github.com/mesonbuild/meson/pull/9304

f3b422d9cc docs: Clarify 'burst' units for QoS
The burst attribute for bandwidth specifies how much bytes can be
transmitted in a single burst. Therefore, the unit is in
multiples of 1024 (thus kibibytes) not SI-like 1000. It has
always been like that.

The 'tc' output is still confusing though, for instance:

  # tc class add dev $DEV parent 1: classid 1:1 htb rate 1000kbps burst 2097152
  # tc class show dev vnet2
  class htb 1:1 root rate 8Mbit ceil 8Mbit burst 2Mb cburst 1600b

Please note that 2097152 = 2*1024*1024. Even the man page is
confusing. From tc(8):

  kb or k        Kilobytes
  mb or m        Megabytes

But I guess this is because 'tc' predates IEC standardisation of
binary multiples and thus can't change without breaking scripts
parsing its output.

And while at it, adjust _virNetDevBandwidthRate struct member
description, to make it obvious which members use SI/IEC units.
