[PATCH 0/3] stubdom: reduce xenstore library dependencies

[Juergen Gross]

Instead of letting the xenstore stubdoms depend on libxenguest and
with that on basically all Xen libraries, only let it depend on the
actually used libraries.

This is in preparation of removing the libxenctrl dependency from
Xenstore and with that the capability to use xenstore-stubdom on
multiple hypervisor versions.

[PATCH 2/3] tools/xenstored: remove unneeded libxenguest reference

[Juergen Gross]

Today the xenstored Makefile contains an unneeded reference to the
not used libxenguest library.

Remove it.

[PATCH 3/3] stubdom: use real lib dependencies for xenstore stubdoms

[Juergen Gross]

Today the build of Xenstore stubdoms depend on libxenguest just because
libxenguest depends on all needed libraries. In reality there is no
dependency on libxenguest for Xenstore stubdoms.

Use the actual dependencies instead.
