Hi manintainers,

This series is to
1. Implement a few methods in core so that a plugin can have control of
   allowing / disallowing certain service connections.
2. Implement the AdminPolicy plugin. The plugin provides interfaces
   AdminPolicySet and AdminPolicyStatus. For each policy, users should
   set the value thorugh AdminPolicySet and query the current setting
   through AdminPolicyStatus. We separeted these two interfaces so that
   developers can assign different groups of users to these interfaces.
   Currently the only policy is ServiceAllowList, which make bluez only
   allow a list of service by specified their UUIDs, but the plugin is
   also expected to provide more controls over other bluez behaviors.
Since the second part is a plugin, it might not be necessary to land in
upstream tree.

Thanks.

Changes in v6:
- include <errno.h> instead of <error.h> in plugins/admin.c

Changes in v5:
- Fix compiler errors in plugins/admin.c

Changes in v4:
- Update commit message (admin_policy -> admin)
- remove old plugins/admin_policy.c

Changes in v3:
- Rename plugins/admin_policy.c -> plugins/admin.c
- Use device_added callback in btd_adapter_driver instead of listen for
  dbus
- Add authorization method in profiles/health/mcap.c and block incoming
  connections in adapter authorization function.

Changes in v2:
- Move bt_uuid_hash and bt_uuid_equal functions to adapter.c.
- Modify the criteria to say a device is `Affected` from any-of-uuid
  to any-of-auto-connect-profile.
- Remove the code to remove/reprobe disallowed/allowed profiles,
  instead, check if the service is allowed in bt_io_accept connect_cb.
- Fix a typo in emit_property_change in
  plugin/admin_policy.c:set_service_allowlist
- Instead of using device_state_cb, utilize D-BUS client to watch device
  added/removed.
- Add a document in doc/
