197d00d21a parser: add support for a generic all rule type
Extend the policy syntax to have a rule that allows specifying all
permissions for all rule types.

  allow all,

This is useful for making blacklist based policy, but can also be
useful when combined with other rule prefixes, eg. to add audit
to all rules.

  audit access all,

5e8567c9e9 parser: rework perms rule merging
Instead of pushing the cmp logic for rule merging into each rule
class make it the default behavior for the perms_rule_t parent class.
Also save off the original perms for the merged rule.

For classes that don't want perms merging add an alternate
dedup_perms_rule_t clase.

cdb5e501d6 parser: add permission merging
By changing the compare function from each rule to use class_rule_t,
instead of perms_rule_t, we temporarily ignore if permissions are
different. If every rule attribute is the same, then the permissions
can be merged. This is done at the perms_rule_t's level.

io_uring rules have the following format:

io_uring [<access_mode>] [<label>],
access_mode := 'sqpoll'|'override_creds'
label := 'label' '=' <target label>
