libvirt/src/qemu/qemu_hotplug.c
Daniel P. Berrange 896104c9f0 Rename and split the macvtap.c file 
Rename the macvtap.c file to virnetdevmacvlan.c to reflect its
functionality. Move the port profile association code out into
virnetdevvportprofile.c. Make the APIs available unconditionally
to callers

* src/util/macvtap.h: rename to src/util/virnetdevmacvlan.h,
* src/util/macvtap.c: rename to src/util/virnetdevmacvlan.c
* src/util/virnetdevvportprofile.c, src/util/virnetdevvportprofile.h:
  Pull in vport association code
* src/Makefile.am, src/conf/domain_conf.h, src/qemu/qemu_conf.c,
  src/qemu/qemu_conf.h, src/qemu/qemu_driver.c: Update include
  paths & remove conditional compilation
