* src/util/storage_file.c: add virStorageFileGetMetadata() so that
  the caller does not need to open the file

Finally, we get to the point of all this.

Move virStorageGetMetadataFromFD() to virStorageFileGetMetadataFromFD()
and move to src/util/storage_file.[ch]

There's no functional changes in this patch, just code movement

* src/storage/storage_backend_fs.c: move code from here ...

* src/util/storage_file.[ch]: ... to here

* src/libvirt_private.syms: export virStorageFileGetMetadataFromFD()

Introduce a metadata structure and make virStorageGetMetadataFromFD()
fill it in.

* src/util/storage_file.h: add virStorageFileMetadata

* src/backend/storage_backend_fs.c: virStorageGetMetadataFromFD() now
  fills in the virStorageFileMetadata structure

Rename virStorageVolFormatFileSystem to virStorageFileFormat and
move to src/util/storage_file.[ch]

* src/Makefile.am: add src/util/storage_file.[ch]

* src/conf/storage_conf.[ch]: move enum from here ...

* src/util/storage_file.[ch]: .. to here

* src/libvirt_private.syms: update To/FromString exports

* src/storage/storage_backend.c, src/storage/storage_backend_fs.c,
  src/vbox/vbox_tmpl.c: update for above changes

* src/util/xml.c: The virXPath... function take extra care to preserve
  the XPath context node (ctxt->node) but in the case of virXPathString
  and virXPathBoolean they forgot to do this on the error path. This
  patch fixes this and move all ctxt->node = relnode instuctions just
  after the xmlXPathEval() to make sure this doesn't happen if this code
  is modified.

Seems standard to include internal.h in order to pull in libvirt.h

* src/util/util.h: include internal.h

Add the virStrncpy function, which takes a dst string, source string,
the number of bytes to copy and the number of bytes available in the
dest string.  If the source string is too large to fit into the
destination string, including the \0 byte, then no data is copied and
the function returns NULL.  Otherwise, this function copies n bytes
from source into dst, including the \0, and returns a pointer to the
dst string.  This function is intended to replace all unsafe uses
of strncpy in the code base, since strncpy does *not* guarantee that
the buffer terminates with a \0.
