[v9.2] "database" object class of contrib/sepgsql

From

The attached patch is a portion that we splitted off when we added
pg_shseclabel system catalog.

It enables the control/sepgsql to assign security label on pg_database
objects that are utilized as a basis to compute a default security
label of schema object.
Currently, we have an ugly assumption that all the pg_database entries
are labeled as "system_u:object_r:sepgsql_db_t:s0", and default
security label of schema is computed based on this assumption. See,
sepgsql_schema_post_create() in sepgsql/schema.c

It also enables initial labeling at sepgsql_restorecon() and
permission checks on relabeling, however, nothing are checked any
more.

Thanks,

Committed, although the fact that it didn't compile until I made
schema.c include pg_database.h makes me wonder how thoroughly you
tested this.

Hmm.. As I did usually, I might build the module and run installation
script and regression test when I submitted this patch.
However, it was fact I submitted a patch with an obvious miss.
Sorry, I'll be careful to check the code being tested.
