[libvirt] [PATCH] Drop ChangeLog generation

[Cole Robinson]

Fedora is perpetually low on space for its live cd, and a bug was filed
asking libvirt to drop the rather large ChangeLog from the RPM:

https://bugzilla.redhat.com/show_bug.cgi?id=977099

Really though, what's the point of a static ChangeLog these days? git
has won, and is far more useful for querying log info than a large
static blob.

This patch drops the ChangeLog generation. In its place there's now
a small stub file pointing to the online git log.

Additionally, the RPM was installing the ChangeLog and other doc
bits twice, once with the daemon and once with the client. Drop the
docs from the daemon package, it requires the client anyways.

 I clipped the removal of ChangeLog-old since it exceeded mail size for
 the list.
