1. separate rom include files and linkscript to esp_rom
2. modefiy "include rom/xxx.h" to "include esp32/rom/xxx.h"
3. Forward compatible
4. update mqtt
This takes the code up to the latest released version of libcoap.
As there have been API changes, coap_client and coap_server in
examples/protocols have been updated to use the new APIs.
Further information on the new libcoap APIs can be found at
https://libcoap.net/doc/reference/4.2.0/
coap_client has been updated to handle BLOCK2 responses from
"coap://californium.eclipse.org"
coap_client has been modified to only send out one request (and wait for
the response)
coap_server has been updated to support Observe subscriptions, and well as
adding in PUT and DELETE handlers to work on the Espressif resource
coap_server and coap_client have had their stack sizes increased.
port/coap_io.c has been added, a copy of libcoap/src/coap_io.c with support
added for systems that do not have RFC 3542 section 20 support.
port/coap_io_socket.c has been removed as a lot of the code is now
replicated in different libcoap files.
Once this PR is place, then adding in DTLS will be a lot simpler (as a
separate PR)

newlib uses significantly more stack space when printing to an
unbuffered stream. To reduce the amount of stack space required to
use the console, don’t disable buffering. linenoise should support
unbuffered stdout instead.
The current API is insufficient to allow the users to set different combinations of connection and discoverable mode
Users should be able to choose the device modes independently:
1. Connectable-
i. Non-connectable mode
ii. Connectable mode
2. Discoverable-
i. Non-discoverable mode
ii. Limited discoverable mode
iii. General discoverable mode
