* src/virsh.c: Implement 'virsh edit', 'virsh net-edit' and
'virsh pool-edit' commands. These edit the XML for domains,
networks and storage pools respectively, and are the
equivalent of doing 'virsh dumpxml; vi foo.xml; virsh define'
* src/Makefile.am, src/.cvsignore: Auto-generate the net-edit
and pool-edit commands.
* docs/virsh.pod: Updated the documentation.
* src/.cvsignore: Ignore *.loT files (generated under Windows).
* proxy/libvirt_proxy.c: Bail out earlier --without-xen.
* src/proxy_internal.c: Don't build proxy client side if
configured --without-xen.
* src/iptables.c, src/iptables.h: Disable this code if
configured --without-qemu.
* src/nodeinfo.c: If no 'uname' function, set model name to
empty string (for Windows).
* src/xen_unified.h, src/util.c, src/test.c: Include <winsock2.h>
on Windows.
* src/util.c: Disable virExec* and virFileLinkPointsTo on
MinGW.
