As suggested by danpb, to fix up the regression caused by last week's VIR_ENUM

Browse Source 
cleanup patch, add a ".defaultFormat" member to .poolOptions.  In
storage_conf.c, if virXPathString(/pool/source/format/@type) returns NULL, then
set the pool type to .defaultFormat; otherwise, lookup the type via
formatFromString.

* src/storage_backend.h src/storage_backend_disk.c
src/storage_backend_fs.c src/storage_backend_logical.c
src/storage_conf.c: Fix up a regression caused by the transition of
the storage backends to VIR_ENUM_IMPL. Before, we would accept
no format type, which would then use whatever the default for the pool
was. But the conversion caused this to instead cause a SEGFAULT,
which isn't good. Introduce a .defaultFormat parameter so that we
restore the previous behavior, although in a more generic format.

* configure.in: Fix syntax error which was breaking RPM builds.
