Add a new landlock_key union and landlock_id structure to support
a socket port rule type. A struct landlock_id identifies a unique entry
in a ruleset: either a kernel object (e.g inode) or typed data (e.g TCP
port). There is one red-black tree per key type.
This patch also adds is_object_pointer() and get_root() helpers.
is_object_pointer() returns true if key type is LANDLOCK_KEY_INODE.
get_root() helper returns a red_black tree root pointer according to
a key type.
Refactor landlock_insert_rule() and landlock_find_rule() to support coming
network modifications. Adding or searching a rule in ruleset can now be
done thanks to a Landlock ID argument passed to these helpers.
Remove unnecessary inlining.
You need to keep the Co-developed-by before the Signed-off-by for my entry.
Got it.

* Refactors commit message, adds a co-developer.
Changes since v6:
* Adds union landlock_key, enum landlock_key_type, and struct
landlock_id.
* Refactors ruleset functions and improves switch/cases: create_rule(),
insert_rule(), get_root(), is_object_pointer(), free_rule(),
landlock_find_rule().
* Refactors landlock_append_fs_rule() functions to support new
landlock_id type.
Changes since v5:

Can you please create a (previous) dedicated patch for all the inlining
changes?
a patch with just inlining changes?
Yes, a new patch with just the inlining changes extracted from this patch.
