When context is de-allocated, other threads can still access the
context lock held within context. Indicating being freed when
coap_free_context() was called worked in most cases, but not all.
Update the Public API equivalent of the libcoap functions that need to be
called when locked with a name suffix of _lkd.
Move matching Public API functions out of coap_threadsafe.c to be coded
just ahead of the newly renamed _lkd function.
Properly define the _lkd function in the appropriate _internal.h file for
documentation, removing the #defines from coap_threadsafe_internal.h.
Tag all the Public API functions that have a _lkd function with COAP_API.
COAP_API can then be defined as to what should be done for that function.
Check libcoap library does not call the original Public API function when
it should be calling the _lkd function by marking the Public API not _lkd
functions as deprecated during the libcoap library build.
[Done by the new COAP_API being defined as __attribute__((deprecated)).]
Work in progress for all the functions that need to be multi-thread safe.

Remove coap_lock_* requirements for testdriver (coap_delete_node()).
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.
