Use struct net to reference CAIF configuration object instead of static variables.
Refactor functions caif_connect_client, caif_disconnect_client and squach
files cfcnfg.c and caif_config_utils.

RCU read_lock and refcount is used to protect in-flight packets.
Use RCU and counters to manage freeing lower part of the CAIF stack if
CAIF-link layer is removed. Old solution based on delaying removal of
device is removed.
When CAIF link layer goes down the use of CAIF link layer is disabled
(by calling caif_set_phy_state()), but removal and freeing of the
lower part of the CAIF stack is done when Link layer is unregistered.

Changes:
o Bugfix: SO_PRIORITY for SOL_SOCKET could not be handled
in caif's setsockopt, using the struct sock attribute priority instead.
o Bugfix: SO_BINDTODEVICE for SOL_SOCKET could not be handled
in caif's setsockopt, using the struct sock attribute ifindex instead.
o Wrong assert statement for RFM layer segmentation.
o CAIF Debug channels was not working over SPI, caif_payload_info
containing padding info must be initialized.
o Check on pointer before dereferencing when unregister dev in caif_dev.c

Previously CAIF supported maximum transfer size of ~4050.
The transfer size is now calculated dynamically based on the
link layers mtu size.
