51ac70d42b Bluetooth: GATT: Refactor subscription API
This removes destroy callback for userdata as bt_gatt_subscribe
doesn't take any user data parameters and that destroy callback
was acctually called with subscribe parameters.

We assume subscription is active if bt_gatt_subscribe returned 0
(ie write command was sent). This is due to remote might be sending
notifications before reply to write.

Also note that bt_gatt_subscribe doesn't take any user data parameters
and that destroy callback was acctually called with subscribe
parameters.

If application would require to pass user data along with parameters
it may use CONTAINER_OF macro along with bt_gatt_subscribe_params.

6645d3f485 Bluetooth: GATT: Remove destroy callback from bt_gatt_discover_params
Instead of destroy callback, call discovery_func with NULL attribute to
indicated that discovery has completed. This makes it clear when
discovery is completed and parameters used for it are no longer used.
Thanks to this application doesn't need to abuse user data destroy
callback for detecting if discovery has completed.

Also note that bt_gatt_discover doesn't take any user data parameter
and that destroy callback was acctually called with discovery
parameters.

If application would require to pass user data along with parameters
it may use CONTAINER_OF macro along with bt_gatt_discover_params.

44541091dc Bluetooth: GATT: Remove unnecessary usage of full UUID structs
To access the 16-bit value of GATT UUIDs it's quite overkill to first
create anonymous UUID structs and then access the value member from
them. We can simplify this a lot with the help of the recently added
UUID value definitions.

bt_gatt_attr_func_t don't return bt_conn which could be used
later on to issue other commands and to application to know
from which connection this results come.

d42a70288b Bluetooth: gatt: Refactor read of attributes as a gatt client
This patch refactor reading of attribute values as a client.
Current MTU size is taken into account to determine if read
procedure has been completed or not.
For now, read procedure will be continued until whole is read,
or stopped by client.
Core Specification says that "The Read Blob Request is repeated
until the Read Blob Response’s Part Attribute Value parameter is
shorter than (ATT_MTU – 1)." (Vol 3, Part G 4.8.3)
Because application didn't know the current MTU value,
there was no way to determine if data received is complete.
