a56cbed603 Bluetooth: ISO: Split ISO broadcast config
Splitt he ISO broadcast config into broadcaster and
sync receiver. This will allow a device that only
wants to one of the roles to have a much more optimized
configuration.

8d20e8d5bc Bluetooth: ISO: Add iso accept info struct
Add a new struct that provides information to the upper
layer when accepting an connected isochronous stream.

The CIG ID and CIS ID makes it possible for the upper layer
to determine which ISO channels are "together" in a group.

5a11a19713 Bluetooth: Iso: Add BT_ISO_SDU_BUF_SIZE macro
Add the BT_ISO_SDU_BUF_SIZE which can be used to declare
the TX buffers for ISO, similar to the BT_L2CAP_SDU_BUF_SIZE
macro for L2CAP.

This also updates the ISO samples to use this as well
updating the SDU check to use
CONFIG_BT_ISO_TX_MTU/CONFIG_BT_ISO_RX_MTU without
subtracting the BT_ISO_CHAN_SEND_RESERVE to make the
API more clear.

3b33ba2320 Bluetooth: shell: Avoid reusing the same label
To avoid hitting the following violation:
Violation to rule 5.7 (Tag name should be unique)

Replace the use of "shell" in the shell as an instance of a pointer to
const struct shell.

a1cf45b26e Bluetooth: ISO: Split connected and broadcast ISO Kconfig
Add a new Kconfig option, BT_ISO_UNICAST, to make it possible
either configure unicast only, broadcast only or both.

This results in some code being moved, but not modified, and
should not effect anything.

3af1f4bac5 Bluetooth: ISO: Make it possible to setup unidirectional CIS
The current iso commands in the shell only supports setting up
a bidirectional stream or unidirectional for central role.
Adding rx/tx/rxtx option to iso listen command to allow for
peripheral side configuration of an iso connection.

04dfcba792 Bluetooth: ISO: Add sequence number to ISO data packets
The sequence number is needed in the appliaction layer to detect lost
packets in the ISO stream in cases where the timestamp is not included.
(Sequence number is mandatory to include where timestamp is optional).
The API for the public metadata have been moved to a public header file.

As the size of the ISO meta data exceeds the default 4 octets net_buf
user_data the public ISO metadata have been moved into a seperate array.
The internal metadata is still stored in net_buf user_data.

This also fixed the user_data overflow on 32 bit systems, caused by
writing the ts into user_data on index 4 to 7, which is outside the 4
allocated bytes.

9d0fb5ec47 Bluetooth: ISO: Remove channel direction
Channel direction was actually a source of confusion since the spec does
actually define the data path direction from controller point of view
meaning input actually means transmit and output receive, also direction
can be configured with different QoS settings.

To make these APIs less confusing and allow QoS to be configured
independently they are now split into RX (receiving) and TX
(transmission) settings including its data path.
