When a TCP connection is established, if there is no data exchange
between the two parties within the set time, the side that enables
TCP Keep-alive will send a TCP probe packet with the same sequence
number as the previous TCP packet. This TCP probe packet is an empty
ACK packet (the specification recommends that it should not contain
any data, but can also contain 1 nonsense byte, such as 0x00.). If
there is no response from the other side after several consecutive
probe packets are sent, it is determined that the tcp connection has
failed, and the connection is closed.
The keep-alive default parameters are aligned with Linux defaults.

This removes the fixed size bt_bap_base, which provides
2 improvements:
1) The RAM usage of the broadcast sink has been reduced.
For the Broadcast Sink sample it is a reduction of 120
octets, but with much better scaling for supporting
more or larger BASEs.
2) The functions to parse BASEs now support arbitrary sized
BASEs, where they were previously restricted by our
local Kconfig options. This allow us to parse any BASE
from a remote device, without encounting memory issues.
We are still memory restricted on the devices we
actually want to sync to.

Iterating over connection list w/o mutex lock could lead to a crash on
constant incoming packet flow. Fix this by:
1. Adding mutex lock when iterating over an active connection list, to
prevent list corruption.
2. Create a copy of the callback and user data pointers before releasing
lock, to prevent NULL pointer dereference in case connection is
released before callback is executed.

Eliminate race between TCP input thread and TCP work queue, when
dereferencing connection. This normally would not manifest itself during
standard TCP operation, but could be a potential opening for abuse, when
the already closed TCP connection is kept being spammed with packets.
The test scenario involved sending multiple TCP RST packets as a
response to establishing the connection, which could result in system
crash. The following changes in the TCP stack made it stable in such
scenario:
1. Use `tcp_lock` when searching for active connections, to avoid
potential data corruption when connection is being removed when
iterating.
2. Avoid memset() during connection dereference, not to destroy mutex
associated with the connection. The connection context is only
cleared during allocation now.
3. Lock the connection mutex while releasing connection.
4. In tcp_in(), after locking the mutex, verify the connection state,
and quit early if the connection has already been dereferenced.
5. When closing connection from the TCP stack as a result of RST or
malformed packet, verify connection state to make sure it's only done
once, even if multiple RST packets were received.

If server registration fails, allow fallback to secondary server,
or fallback to bootstrap.
Also allow fallback to different bootstrap server.
Add API to tell RD client when server have been disabled by
executable command.
Changes to RD state machine:
* All retry logic should be handled in NETWORK_ERROR state.
* New state SERVER_DISABLED.
* Internally disable servers that reject registration
* Temporary disable server on network error.
* Clean up all "disable timers" on start.
* Select server first, then find security object for it.
* State functions return void, error handling is done using states.
* DISCONNECT event will only come when client is requested to stop.
* NETWORK_ERROR will stop engine. This is generic error for all kinds
of registration or network failures.
* BOOTSTRAP_REG_FAILURE also stops engine. This is fatal, and we cannot
recover.
Refactoring:
* Server selection logic is inside server object.
* sm_handle_timeout_state() does not require msg parameter. Unused.
* When bootstrap fail, we should NOT back off to registration.
This is a fatal error, and it stops the engine and informs application.
