Bluetooth had two public types with similar name _bt_gatt_ccc and
bt_gatt_ccc, but for absolutely different purposes.
That caused misunderstanding of relationship of them and cases
where to use which one.
Commit changes name of _bt_gatt_ccc to more suitable by usage and
improves documentation of it.
Additionally, it changes name of BT_GATT_CCC_INITIALIZER
to correspond the type name.

The stack will no longer implicitly set the data path
for ISO channel, and the responsibility for doing that is
now for the upper layers/applications.
This provides additional flexibility for the higher layers
as they can better control the values and timing of the data
path, as well as support removing and even reconfiguring the
data path at will.
This also removes some complexity from the stack.
This commit also fixed a inconsistency in the disconnected
handler. CIS for centrals as well as BIS were still valid
bt_iso_chan channels in the disconnected callback,
but CIS for peripherals were completely cleaned up at this
point. This issue is fixed by moving the disconnected callback
handling to before the code to cleanup the channel for
peripherals.
Since there is a difference in how you remove data paths
depending on the GAP role (central/peripheral), the
iso_info struct type has been expanded to be more
concise of which type of CIS it is.

Fix HCI command buffer allocation failure, that can cause

When Controller to Host data flow control is supported in
the Controller only build, ensure that BT_BUF_CMD_TX_COUNT
is greater than or equal to (BT_BUF_RX_COUNT + Ncmd),
where Ncmd is supported maximum Num_HCI_Command_Packets in

Because the number of ACL RX buffers must be at least the number of
maximum connections plus one, increasing `CONFIG_BT_MAX_CONN` could
inadvertently lead to a build failure if the number of ACL RX buffers is
not also increased. This dependency may not be obvious to users.
To address this issue, this commit deprecates the
`CONFIG_BT_BUF_RX_COUNT` Kconfig symbol and computes the value in
`buf.h` using the new `BT_BUF_RX_COUNT` define. Note that the default
value and the minimum range value have been changed to 0 to "disable"
the option.
Additionally, to allow users to increase the number of ACL RX buffers,
this commit introduces the new `CONFIG_BT_BUF_RX_COUNT_EXTRA` Kconfig
symbol. The value of this symbol will be added to the computed value of
`BT_BUF_RX_COUNT`.
The configurations of tests and samples have been updated to reflect
these changes.

Reducing the heap requirement for the hci_ipc sample from

The heap requirement is not documented, and it is unclear why

be investigated further.

Add conversion macros from milliseconds to various units.
The purpose of these macros is to make it more clear/easier
for users to set and read values using milliseconds rather
than the various BT units which may be in 0.625, 1.25 or 10ms
units.
This is especially useful when comparing related values using
different units, such as advertising interval (0.625ms units)
and periodic advertising interval units (1.25ms units).
Users will have to be aware that these macros can provide slightly
different values than what is provided, if the provided values
do not match the units.

Refactors teh BIS bitfield values used for ISO
and BAP.
Previously BIT(1) meant BIS index 1, which was a Zephyr choice
in the early days of ISO, as the BT Core spec did not use
a bitfield for BIS indexes.
Later the BASS specification came along and defined that
BIT(0) meant BIS index 1, which meant that we had to shift BIS
bitfields between BAP and ISO.
This commit refactors the ISO layer to use BIT(0) for Index 1 now,
which means that there is no longer a need for conversion
between the BAP and ISO layers, and that we can use a value
range defined by a BT Core spec (BASS).

The current TX pattern in the host is to try to push a buffer through all
the layers up until it is ingested by the controller.
Since sending can fail at any layer, we need error-handling and separate
retry logic on pretty much all layers. That logic obscures the "happy path"
for people trying ot understand the code.
This commit inverts the control, in a way that doesn't require changing the
host or HCI driver API (yet):
Layers don't send buffers synchronously, they instead put their buffer in a
private queue of their own and raise a TX flag on the lower layer. Think of
it as a `READY` interrupt line that has to be serviced by the lower layer.
Sending is now non-blocking, rate depends on the size of buffer pools.
There is a single TX processing function. This can be thought as the
Interrupt Service Routine that will handle the `READY` interrupt from the
layers above.
That `tx_processor()` will then attempt to allocate enough resources in
order to send the buffer through to the controller. This allocation logic
does not block.
After acquiring all the resources, the TX processor will attempt to pull
data from the upper layer. The upper layer has to figure out which buffer
to pass to the controller. This is a good spot to put scheduling or QoS
logic in the upper layer.
Notes:
- user-facing API for tuning QoS will be implemented in a future patch
- this scheme could (and probably will) be extended to upper layers (e.g.
ATT, L2CAP CoC segmentation).
- this patch removes the `pending_no_cb()` memory optimization for
clarity/correctness. It might get re-implemented after a stabilization
period. Hopefully with more documentation.
