Make it more obvious which parameters are read-only and not being
modified and allow callers to pass const pointers.

Both boolean and tunable keywords are processed by define_bool_tunable(),
argument 0 and 1 would be passed for boolean and tunable respectively.
For tunable, a TUNABLE flag would be set in cond_bool_datum_t.flags.
Note, when creating an if-else conditional we can not know if the
tunable identifier is indeed a tunable(for example, a boolean may be
misused in tunable_policy() or vice versa), thus the TUNABLE flag
for cond_node_t would be calculated and used in expansion when all
booleans/tunables copied during link.

1. Add a uint32_t "flavor" field and an ebitmap "roles" to the
role_datum_t structure;
2. Add a new "attribute_role" statement and its handler to declare
a role attribute;
3. Modify declare_role() to setup role_datum_t.flavor according
to the isattr argument;
4. Add a new "roleattribute" rule and its handler, which will record
the regular role's (policy value - 1) into the role attribute's
role_datum_t.roles ebitmap;
5. Modify the syntax for the role-types rule only to define the
role-type associations;
6. Add a new role-attr rule to support the declaration of a single
role, and optionally the role attribute that the role belongs to;
7. Check if the new_role used in role-transition rule is a regular role;
8. Support to require a role attribute;
9. Modify symtab_insert() to allow multiple declarations only for
the regular role, while a role attribute can't be declared more than once
and can't share a same name with another regular role.

This patch adds support for using the last path component as part of the
information in making labeling decisions for new objects. A example
rule looks like so:
type_transition unconfined_t etc_t:file system_conf_t eric;
This rule says if unconfined_t creates a file in a directory labeled
etc_t and the last path component is "eric" (no globbing, no matching
magic, just exact strcmp) it should be labeled system_conf_t.
The kernel and policy representation does not have support for such
rules in conditionals, and thus policy explicitly notes that fact if
such a rule is added to a conditional.
