Luis R. Rodriguez dff4c31163 autoconf: xen: enable explicit preference option for xenstored preference
As it stands oxenstored will be used by default if ocaml tools are
found, the init system will also try to use oxenstored first if its
found otherwise the cxenstored will be used. Lets simplify the init
script and let users be explicit about the preference through configure.

This adds support to let you be explicit about the xenstored preference,
you can only use one of these two options:

./configure --with-xenstored=xenstored
./configure --with-xenstored=oxenstored

We continue with the old behaviour and default oxenstored will be used
but only if you have ocaml dependencies. Since the xenstored preference
is explicit now and since we require configure substitutions for it we
make use of the AX_XEN_EXPAND_CONFIG() helpers as otherwise substitution
for SBINDIR is not propagated from the top level configuration.

All this allows us to simplify the init script to use the configured
xenstore from the start. We update the sysconfig/default xencommons file
with the paths for the different options though, this can be used by
users to override the default xenstored, this follows the old behaviour
but we now just explicitly provide the full configured paths for users.

As before, changing the xenstore requires a reboot.

In order to help with documentation we update the README with some
details on configure usage refer to the wiki [0] [1] [2] for more elaborate
details.

Since we are now parsing an entry within Paths.mk.in on tools we let
the move the parsing of the file to be the tool's configure.
