[libvirt] [PATCH 10/4] virsh: split out virsh-interface.c

[Eric Blake]

Another relatively easy split, since helper functions were fixed
in the previous patch.

* tools/virsh-interface.h: New file.
* tools/Makefile.am (virsh_SOURCES): Build it.
* tools/virsh.c: Use new header.
* tools/virsh-interface.c: Likewise.
(vshCommandOptInterfaceBy): Check flags.
