Upstream author, Mikio Hirabayashi, released qdbm 1.8.28 that includes qdbm 1.8.27-2 fixes. In addition, as I suggested, qdbm now provides qdbm.pc so that we can use pkg-config to find appropriate cflags and libs for qdbm.

He bumped up soname to libqdbm.so.11, but the difference from prior version is just new field addition in database file (version field), so there are no API changes, so I think it is unnecessary soname change...
