Luiz Augusto von Dentz 14ff92cea0 Bluetooth: Handle ATT execute write request
This introduce a new callback called flush to bt_gatt_attr to indicate
when and attribute can cache data, the data is automatically flushed if
regular write request happens and in case of prepare write it checks if
flush is supported otherwise return an error, then upon receiving an
execute write it perform flush over the entire database and respond
with result:

< ACL Data TX: Handle 42 flags 0x00 dlen 6
      ATT: Execute Write Request (0x18) len 1
        Flags: Immediately write all pending values (0x01)
> ACL Data RX: Handle 42 flags 0x02 dlen 5
      ATT: Execute Write Response (0x19) len 0

Luiz Augusto von Dentz aa1260999e Bluetooth: Fix persisting CCC config for non-bonded devices
The spec says that CCC shall only be persistent accross connection for
bonded devices:

  'The Client Characteristic Configuration descriptor value shall be
  persistent across connections for bonded devices. The Client Characteristic
  Configuration descriptor value shall be set to the default value at each
  connection with non-bonded devices'.

To handle this now each configuration has a valid field indicating if the
configuration is valid.

Johan Hedberg 5e16f9b849 Bluetooth: Add missing include to gatt.h needed by ARRAY_SIZE
All public headers should be self-contained. Since gatt.h uses the
ARRAY_SIZE macro it should also include the <misc/util.h> header file
that provides it.

Luiz Augusto von Dentz e8e0fbe63a Bluetooth: Add BT_GATT_CCC macro
BT_GATT_CCC uses _bt_gatt_ccc internal struct to handle peer
configurations and special helpers to read and write to minimize the
code necessary to handle CCC in the task.

Note this not yet include handling of connection and disconnection but
the idea is that the core would automatically disable the configurations
while disconnected and re-enable once peer connect back.

Luiz Augusto von Dentz c6ce7792a7 Bluetooth: Add Bluetooth remote address to attribute callbacks
To implement CCC properly it is required to know the remote address since
it is per client, futhermore bt_gatt_notify requires an address where to
send the notification.
