Info structure in advertising PDUs.
Signed-off-by: Vinayak Kariappa Chettimada <vich@nordicsemi.no>
This adds support to allow advertising PDUs to be linked which is
required to send advertising trains, i.e. AUX_CHAIN_IND.
PDUs are linked with a simple single-linked list, the pointer to next
PDU is stored at the very end of PDU buffer. This prevents it from
being overwritten if PDU is modified and allows for build time offset
calculation.
There are few helpers added to make handling easier, e.g.:
- get next linked PDU
- get last linked PDU
- link one PDU to another
- link PDU at the end
- release all linked PDUs (except for 1st)

Change use of dedicated memory pool for linked list nodes for
node_rx_iq_report to common mem_link_rx. Former solution had
a drawback. Released link nodes may be enqueued to wrong memory
pool. E.g. link related with nopde_rx_iq_report went to common
link memory pool, whereas link nodes from common pool were enqueued
to dedicated list.
The solution was working because links have the same memory layout,
just different memory pools they originated from.
The problem may occur if one of those link memory pools is reset.
Then the same link may be used by node_rx and node_rx_iq_report
at the same time, causing controller failure.

Disable of CTE sampling for periodic advertising sync PDUs may be
interrupted by radio event. In such situation, TX thread will be
handled before RX thread delivers IQ samples report to host. In
this case RX thread would deliver IQ samples report after CTE
sampling was disabled.
To avoid such situation RX thread has to check if:
- CTE sampling is not disabled,
- CTE sampling was not requested to be disabled after start of radio
event.
CTE sampling configuration is double buffered. Updated configuration is
swapped at the beginning of radio event.
If CTE sampling is diabled or requested to disable (next radio event
didn't start), the IQ samples report should be dropped by RX thread
and should not be delivered to host.

Refactor and simplify the bluetooth buffer configurations to improve the
easy of configurations and eliminate invalid ones.
By moving configurations out of host and controller specific
configurations and into a common one it becomes easier to configure
the host and controller separately as the same configurations can be
used as would be for a combined build.
All HCI configurations are now given exluding the matching HCI header,
which eases the configuration as the application don't have to know the
different header sizes.
The BT_RX_BUF_LEN is split into ACL and Event, as well as the suprising
use of Command size.
BT_L2CAP_RX_MTU is removed as the stack does not support reassembling of
HCI ACL data to larger L2CAP PDUs. The application will have to set
ACL RX size and account for the L2CAP PDU header itself.
BT_EATT_RX_MTU was removed as it is only used for setting a different
default value for another option which leads to the stuck kconfig symbol
problem.
The configurations can be updated according to the table below:
** New configuration | ** Old configuration
All configurations
BT_BUF_ACL_RX_SIZE | BT_L2CAP_RX_MTU + 4
BT_BUF_ACL_RX_SIZE | BT_RX_BUF_LEN - 4
BT_BUF_EVT_RX_SIZE | BT_RX_BUF_LEN - 2
BT_BUF_CMD_TX_SIZE | BT_RX_BUF_LEN - 3
BT_BUF_CMD_TX_COUNT | BT_HCI_CMD_COUNT
BT_BUF_EVT_RX_COUNT | BT_RX_BUF_COUNT
BT_BUF_ACL_RX_COUNT | BT_RX_BUF_COUNT
BT_BUF_ACL_RX_COUNT | BT_ACL_RX_COUNT
BT_BUF_EVT_DISCARDABLE_SIZE | BT_DISCARDABLE_BUF_SIZE - 2
BT_BUF_EVT_DISCARDABLE_COUNT | BT_DISCARDABLE_BUF_COUNT
Controller-build
BT_BUF_ACL_TX_SIZE | BT_CTLR_TX_BUFFERS_SIZE
BT_BUF_ACL_TX_COUNT | BT_CTLR_TX_BUFFER
HCI-bridge
BT_BUF_ACL_TX_SIZE | BT_HCI_ACL_DATA_SIZE
BT_BUF_ACL_TX_COUNT | 6
Fixed invalid configurations setting either BT_L2CAP_RX_MTU or
BT_CTLR_DATA_LENGTH_MAX larger than BT_RX_BUF_LEN could lead to buffer
overruns.
Fix advertising report max data length calculation.
This always used the BT_DISCARDABLE_BUF_SIZE macro but this feature
can be turned off and advertising reports will be allocated from the RX
buffer in that case. Also controller-build does not have this buffer
(in hci_raw.c). Also the wrong HCI header was used in the calculation,
HCI event header should have been used instead of HCI ACL header.
