Immediate logging is not compatible with the software-based controller
due to the additional ISR latency that it introduces. Ensure that
deferred logging is in use whenever using the software-based LL.

Fix bluetooth config dependencies where the definitions depend on other
definitions.
BT_RX_PRIO is not always defined in a controller only build.
BT_CTLR_TX_BUFFER_SIZE does not depend on BT_CTLR, but BT_LL_SW.

Invalid configurations should be detected during configuration instead
of during compilation whenever possible.
This patch replaces a BUILD_ASSERT on CONFIG_SYSTEM_WORKQUEUE_PRIORITY
with what is intended to be an equivalent Kconfig restriction.

The HCI command buffers are the only ones with more than 4 bytes of
required user data. Move the user data into a separate array and do
the mapping with the help of net_buf_id(). After this, it will be
possible to reduce the default net_buf user data size from 8 to 4.

Redesign of the net_buf_simple and net_buf structs, where the data
payload portion is split to a separately allocated chunk of memory. In
practice this means that buf->__buf becomes a pointer from having just
been a marker (empty array) for where the payload begins right after
the meta-data.

Rename the BT_CONTROLLER prefix used in all of the Kconfig variables
related to the Bluetooth controller to BT_CTLR.

The API name space for Bluetooth is bt_* and BT_* so it makes sense to
align the Kconfig name space with this. The additional benefit is that
this also makes the names shorter. It is also in line with what Linux
uses for Bluetooth Kconfig entries.
Some Bluetooth-related Networking Kconfig defines are renamed as well
in order to be consistent, such as NET_L2_BLUETOOTH.

Added BUILD_ASSERT check for Tx and Rx thread priorities.
The Tx thread priority shall be higher than Rx thread
priority in order to correctly detect transaction violations
in ATT and SMP protocols. The Number of Completed Packets
for a connection shall be processed before any new data is
received and processed for that connection.
The Controller's priority receive thread priority shall be
higher than the Host's Tx and the Controller's Rx thread
priority.

The Bluetooth subsystem assumes execution of its system threads in
cooperative priority, including the system workqueue and the thread
that interact with the controller (i.e. calling bt_send). This commit
adds a compile-time check for the system workqueue priority and
documentation for the bt_send API call.
