This patch adds the common code for outputting drive sizing
information, when a user has requested the new API flag from
the previous patch.
* src/util/virstoragefile.h (_virStorageSource): Add physical, to
mirror virDomainBlockInfo.
* docs/schemas/domaincommon.rng (storageSourceExtra): New define.
* src/conf/domain_conf.c (virDomainDiskDefFormat): Output sizing
when flag is set.
(DUMPXML_FLAGS): Add new flag.
