[BlueZ,v2,0/2] Optionally require security for notify/indicate

Message

In some cases, it is desirable to require encryption and/or
authentication for server-initiated updates, as they may contain
sensitive data.

Currently, there is no way to do this with BlueZ.

Here is a query about this feature from 2019:

This patch implements this feature by introducing new `x-asynchronous`
flags that allow a user to restrict access to a characteristic's CCCD
(as well as documentation for those flags).

Changes in v2:
- Fix line-width issues brought up by CI

Dagan Martinez (2):
  gatt: allow GATT server to dicate CCC permissions
  doc/gatt-api: Add 'X-asynchronous` permissions
