Eric Blake b279e52f7b maint: prefer enum over int for virstoragefile structs 
For internal structs, we might as well be type-safe and let the
compiler help us with less typing required on our part (getting
rid of casts is always nice).  In trying to use enums directly,
I noticed two problems in virstoragefile.h that can't be fixed
without more invasive refactoring: virStorageSource.format is
used as more of a union of multiple enums in storage volume
code (so it has to remain an int), and virStorageSourcePoolDef
refers to pooltype whose enum is declared in src/conf, but where
src/util can't pull in headers from src/conf.

* src/util/virstoragefile.h (virStorageNetHostDef)
(virStorageSourcePoolDef, virStorageSource): Use enums instead of
int for fields of internal types.
* src/qemu/qemu_command.c (qemuParseCommandLine): Cover all values.
* src/conf/domain_conf.c (virDomainDiskSourceParse)
(virDomainDiskSourceFormat): Simplify clients.
* src/qemu/qemu_driver.c
(qemuDomainSnapshotCreateSingleDiskActive)
(qemuDomainSnapshotPrepareDiskExternalBackingInactive)
(qemuDomainSnapshotPrepareDiskExternalOverlayActive)
(qemuDomainSnapshotPrepareDiskInternal): Likewise.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
