[PATCH v2 1/2] libxl: xl mem-max et consortes must update static-max in xenstore too

[Daniel Kiper <daniel.kiper@oracle.com>]

xl mem-max et consortes must update static-max in xenstore too.
Without this patch there is no chance to increase memory reservation
for given domain above memory limit defined in config file. It means
that memory hotplug is practicaly unusable without this patch.
