Hi,

To simplify code for new access types [1], add 2 new helpers:
- landlock_merge_access_masks()
- landlock_match_ruleset()

The last patch uses these helpers to optimize Landlock scope management
like with filesystem and network access checks.

[1] https://lore.kernel.org/r/3433b163-2371-e679-cc8a-e540a0218bca@huawei-partners.com

Previous version:
v1: https://lore.kernel.org/r/20241001141234.397649-1-mic@digikod.net

Regards,
