Series [1/4] libsepol/cil: Provide option to allow qualified names in declarations | expand

Commit Message

Provide the option "-Q" or "--qualified-names" to indicate that the
policy is using qualified names.

Using qualified names means that declaration names can have "dots"
in them, but blocks, blockinherits, blockabstracts, and in-statements
are not allowed in the policy.

The libsepol function cil_set_qualified_names() is called with the
desired value for the CIL db's "qualified_names" field.
