Jon Shallow 8559e40cce async: Fix session->ref assertion failure and timeout values ...

Calling coap_free_context() does not free off any async entries, and so
raises assertion errors when coming to freeing off sessions if any async
entries exist.

async_data_t is a union, but the size of val and ptr are not the same - so
usage can have uninitialized data - hence bad timeout values.

Makefile.am:

Do not expose coap_delete_all*() functions.

examples/coap-server.c:

Fix async_data_t issue.

examples/etsi_iot_01.c:

Fix 32 bit compiler warnings using same logic as coap-server for holding the
async timeout value.

examples/lwip/Makefile:

Include async.c for the LwIP build.

include/coap2/async.h

Define coap_delete_all_async() function.

include/coap2/net.h
include/coap2/resource.h

Document coap_delete_all*() functions as internal.

libcoap-2.map
libcoap-2.sym

Remove non-exposed coap_delete_all*() functions.

src/async.c

Provide coap_delete_all_async() function.

src/net.c

Call coap_delete_all_async() from within coap_free_context().
