A duplicate CON message is sent by the server if the client's ACK to the original
confirmable message did not reach the server.
See issue #1306 for full description: https://github.com/obgm/libcoap/issues/1306
Optional compile time thread safe code supported.
Locking is done at the coap_context_t level, and if enabled is primarily
done coap_threadsafe.c and coap_threadsafe_internal.h.
coap_threadsafe_internal.h causes coap_X() to get mapped to coap_X_locked()
throughout the libcoap library code with the exception of coap_threadsafe.c
if thread safe is enabled.
coap_debug.h: Support logging level set to _COAP_LOG_EMERG
coap_pdu.h: handle small ints
coap_pdu_internal.h: handle small ints
coap_session_internal.h: handle small ints
coap_uthash_internal.h: handle small ints
coap_block.c: Handle small ints
coap_debug.c: Fix use of vsnprintf() and vfprintf()
coap_pdu.c: Handle small ints
coap_tinydtls.c: Handle small ints
coap_uri.c: Fix alignment issue in coap_new_uri()
uncrustify run on RIOT examples to conform to RIOT's coding standards/
Reduce timeout to 1 second and enter established state for servers that
only partially implement RFC8323 for TCP support, but do not send a CSM.
Add new coap_context_set_csm_timeout_ms() to control the value of the timeout.
This then makes sure that all things libcoap are properly initialized
before use, and coders realize they need to do this.
Note: coap_new_context() continues to make sure that coap_startup()
is invoked if not done previously, but this may be too late.
