src/conf/storage_conf.c: Add virStoragePoolMatch to filter the
pools; Add virStoragePoolList to iterate over the pool objects
with filter.
src/conf/storage_conf.h: Declare virStoragePoolMatch,
virStoragePoolList, and the macros for filters.
src/libvirt_private.syms: Export helper virStoragePoolList.
