Add some helpers for handling filenames which might need different
implementations between stubdom and daemon environments:
- expansion of relative filenames (those are not really defined today,
just expand them to be relative to /var/lib/xen/xenstore)
- expansion of xenstore_daemon_rundir() (used e.g. for saving the state
file in case of live update - needs to be unchanged in the daemon
case, but should result in /var/lib/xen/xenstore for stubdom)

Mount the 9pfs device in stubdom enabling it to use files.
This has to happen in a worker thread in order to allow the main thread
handling the required Xenstore accesses in parallel.

All of the socket handling is needed only when running as daemon.
Move it into posix.c, allowing to remove the NO_SOCKETS macro.

All of the log-pipe handling is needed only when running as daemon.
Move it into posix.c. This requires to have a service function in the
main event loop for handling the related requests and one for setting
the fds[] array, which is renamed to poll_fds to have a more specific
name. Use a generic name for those functions, as socket handling can
be added to them later, too.

Move systemd handling to a new late_init() function in posix.c.
This prepares a future removal of the NO_SOCKETS macro.

Some xenstored initialization needs to be done in the daemon case only,
so split it out into a new early_init() function being a stub in the
stubdom case.
Remove the call of talloc_enable_leak_report_full(), as it serves no
real purpose: the daemon only ever exits due to a crash, in which case
a log of talloc()ed memory hardly has any value.

Rename the xenbus_evtchn() function to get_xenbus_evtchn() in order to
avoid two externally visible symbols with the same name when Xenstore-
stubdom is being built with a Mini-OS with CONFIG_XENBUS set.

In tools/xenstore there are living xenstored and xenstore clients.
They are no longer sharing anything apart from the "xenstore" in their
names.
Move the xenstored sources into a new directory tools/xenstored while
dropping the "xenstored_" prefix from their names. This will make it
clearer that xenstore clients and xenstored are independent from each
other.
In order to avoid two very similar named directories below tools,
rename tools/xenstore to tools/xs-clients.
Drop the make targets [un]install-clients as those are not used in
the Xen tree.
