[1] closes gap in virDomainObjListRemove so that concurrent thread can
not step in and obtain the domain while domain is temporary unlocked. But
there is another gap exist:
thread B - executes create API
thread C - executes undefine API
- thread A executes some job on domain
- threads B and C obtains domain from list and wait for job condition
- thread A finishes its job and C grabs job condition, removes domain
from list and finishes
- thread B grabs job condition and start the domain, unfortunately
is not in the list already

SPICE ports cleanup looks overly complicated. We can just set *reserved
flags whenever port is reserved (auto or non auto).
Also *Reserved flags are not cleared on stop in case of reconnect with
autoport (flags are set on reconnect in qemuProcessGraphicsReservePorts
call). Yeah config is freed in the end of stopping domain but still.

Docutils-0.17 switched to using <main> instead of a <div
class='document'> and <section> instead of <div class='section'>.
To ensure that our pages still work we need to slightly adapt our XSL
stylesheet to select the <main> tag properly and adapt the CSS to also
select the 'section' element instead of a class and to apply to a <main>
tag with the appropriate names.
Docutils-0.17 also changed to use 'h2' for section heading instead of
'h1'.
Note the styles applied to the 'main' element with certain id can't be
made more universal by just applying to the id itself, as in certain
cases (e.g. 'documentation') we also have sections with that name. This
was previously ensured by also matching the 'document' class which would
make it equal to the 'main' element.

While the content is slightly outdated it's still a good primer on how
an API call traverses through the client library and to the remote
driver.
To make the page useful, this commit:
- removes the paragraphs which were intended to serve as a directory
page for the 'internals' subdirectory
- adds a note saying that some facts might not be up to date
- adds linking to this page from the kbase directory page
- adds more monospace formatting around function names

Historically we had two top level XSL files for top level and nested

We can instead pass the variable as argument from the build system so
that we have just one XSL file and also allow for more nested document
trees in the future.

The aim of 'restrictive' numatune mode is to rely solely on
CGroups to have QEMU running on configured NUMA nodes. However,
we were never setting the cpuset controller when a domain was
starting up. We are doing so only when
virDomainSetNumaParameters() is called (aka live pinning).
This is obviously wrong. Fortunately, fix is simple as
'restrictive' is similar to 'strict' - every location where
VIR_DOMAIN_NUMATUNE_MEM_STRICT occurs can be audited and
VIR_DOMAIN_NUMATUNE_MEM_RESTRICTIVE case can be added.
