libvirtd creates libvirt-sock in a directory selected by the arguments
you passed to configure.  The configuration file is optional (it is up
to you to create it if you want it - libvirt merely reads it if it exists).

Hmm - I wonder if we have a flaw in our documentation - the name
$HOME/.libvirt/libvirt-sock implies that the socket is NOT in the
abstract namespace; I know we recently changed where qemu:///session
looks for its socket, but I don't remember if the change was from
abstract to named, or from named to abstract.

But really, a lot of your questions sound like they are all stemming
from the fact that you are building your own libvirt, but not setting
the same configure arguments as your distro, and then you are
mis-matching self-built and distro files which have been configured to
look into different locations.  My advice would be to rebuild libvirt
using the same configure arguments as your distro, so that everything
looks in the same place.
