41afd838aa Bluetooth: Crypto: Fix naming of params
The naming and documentation of the parameters was inconsistent with
their actual meaning and the implementation - enc_data and plaintext
were swapped.
Also, the parameter names in the file aes_ccm.c were completely
different from the ones in the header. Since all functions in the
header file are consistent in their parameter naming, I chose to make
the implementation follow the header and not the other way around.

98321c61fb bluetooth: host: Allow concurrent advertising with multiple ids
The HCI specification creates additional complexity to allow this
configuration:
 - When a connection gets established, we need to know which
   identity the HCI_LE_Connection_Complete event corresponds to.
 - The identity is a property of the advertising set.
   Therefore we need the advertising handle.
 - The advertising handle is part of the
   HCI_LE_Advertising_Set_Terminated event and is not part of
   the HCI_LE_Connection_Complete event. Therefore
   the information of both events needs to be combined.

By spec the LE_Connection_Complete comes first. Therefore we cache
this event until the identity is available.
The event is only cached when a connection gets established as
that is the only case where we need to resolve the identity.

As the caching requires more resources, it is only enabled if the
application requires multiple advertising sets and multiple
identities.

The host maps the HCI_LE_Advertising_Set_Terminated event with
the HCI_LE_Connection_Complete event by comparing the connection
handles.

6483e12a8a Bluetooth: Refactor bluetooth buffer configuration for simplification
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.
