6abc1273cf capabilities: Allow suppressing error message from virCapabilitiesDomainSupported()
In a few cases (CH driver) we want
virCapabilitiesDomainSupported() just to check whether given
virtType is supported and report a different error message (that
suggests how to solve the problem). Introduce reportError
argument which makes the function report an error iff set.

a9f76d6ab7 Don't overwrite error message from 'virXPathNodeSet'
'virXPathNodeSet' returns -1 only when 'ctxt' or 'xpath' are NULL or
when the 'xpath' string is invalid. Both are programming errors. It
doesn't make sense for the code to overwrite the error message for
anything supposedly more relevant.

The majority of calls to 'virXPathNodeSet' already didn't do this, so
this patch fixes the rest to prevent it from spreading again.

95e6615cd2 systemd: Set service_extra_in/socket_extra_in everywhere
It's somewhat confusing that some of the services have a
corresponding foo.service.extra.in and foo.socket.extra.in, some
have just one of the two, and some have neither.

In order to make things more approachable, make sure that both
files exists for each service.

In most cases the extra units are currently unused, so they will
just contain a comment briefly explaining their purpose and
pointing users to meson.build, where they can find more
information. The same comment is also added to the top of
extra units that already have some contents in them for
consistency.

When this option is enabled (default=false), then it will no longer

discard to the lower layer.

This was implemented to avoid fragmentation within the qcow2 image.

84e9fd068c conf: extend xmlopt with job config & add job object into domain object
This patch adds the generalized job object into the domain object

Because of this, the job object needs to be created and set

xmlopt with possible job config containing virDomainJobObj
callbacks, its private data callbacks and one variable
(maxQueuedJobs).

This patch includes:
* addition of virDomainJobObj into virDomainObj (used in the
  following patches)
* extending xmlopt with job config structure
* new function for freeing the virDomainJobObj
