When using bt_gatt_discover with BT_GATT_DISCOVER_CHARACTERISTIC the
read callback would be set to bt_gatt_attr_read_chrc which would attempt
to access the next attribute which in this case would not be set since
the value attribute is no fetched by the discovery, the spec actually
omit the value handle saying it should always be the first attribute to
appear after the characteristic thus we can assume it to be handle + 1.

Removing help "options" from shell API.
Currently SHELL_OPT macro is not used by users. What is more
commit: a89690d10f ignores possible options created in
command handler by the user. As a result they are not printed
in help message.
Second, currntly implemented "options" in command handlers options are
implemented without SHELL_OPT macro.
And last but not least this change will allow to implement
help handler in a way that user will not need to think about calling
functions printing help in a command handler.

When we're acting as a Friend for an LPN, we need to consider all
elements of the LPN. The information of how many elements the LPN has
is provided in the Friend Request message, however until now the code
did not do anything with this information.
Fix the issue by tracking the number of elements for each LPN and
update the unicast address matching code to take this into account.

There is not an easy way to relate an application's user_data to a
connection. One way is to save a pointer to bt_conn in the
application's user_data array upon connection establishment.
Each connection related callback function will have to loop for all
user_data and compare the saved pointer to the passed bt_conn
pointer. This is inefficient if there are many callback activations
during the connection.
This change makes the internal bt_conn mapping function accessible to
applications in conn.h. The function name is changed to
bt_conn_index() to clearly indicate that the function returns an
index of an array.
Add an ASSERT to catch illegal parameter.

Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
Application may need to handle the write differently depending on the
write operation so this adds a flag called BT_GATT_WRITE_FLAG_CMD which
can then be checked by the callback, for instance one can respond with
BT_ATT_ERR_WRITE_REQ_REJECTED when that flag is not set which should
indicate to the client to use write command instead.

In Bluetooth 5 the definition of LE security mode 1, has changed.
LE Security Mode 1 level 4 requires authenticated LE Secure Connections
pairing with encryption using a 128-bit strength encryption key.
This also changes the behaviour when a security request and response
would end up with a security level that is lower than the one requested.
Before pairing would complete, and the link would disconnect with error
authentication failure. Instead a SMP will abort pairing with error code
authentication requirement, or encryption key size.
