7dbf01afad coap: move mbedTLS config options from component to examples
CoAP component relies on some mbedTLS crypto configuration
options, e.g. DTLS and PSK. These configuration options if
selected, have footprint impact on generic TLS examples like
https_request or https_ota as well.

Footprint of https_request example with/without change is per below:

$ ./tools/idf_size.py new_https_request.map --diff old_https_request.map

<CURRENT> MAP file: new_https_request.map
<REFERENCE> MAP file: old_https_request.map
Difference is counted as <CURRENT> - <REFERENCE>, i.e. a positive number means that <CURRENT> is larger.
Total sizes of <CURRENT>:                                                 <REFERENCE>     Difference

This commit moves relevant config options to CoAP specific examples
and also adds some run time warnings if they are kept disabled.

31b2702387 esp_netif, examples: esp_netif_init() moved into ESP_ERROR_CHECK()
esp_netif_init() returns standard esp_err_t error code (unlike tcpip_adapter init), so shall be checked for the return value
Also to make the initialization code more consistent.

430b737760 Fix libcoap building with various MbedTLS compile time options

configurations.

components/coap/component.mk:
components/coap/port/coap_notls.c:
components/coap/port/include/coap_config_posix.h:

Add in the ability to compile and run if MbedTLS does not have any TLS
mode enabled.

examples/protocols/coap_client/main/coap_client_example_main.c:

Inform user that MbedTLS Client Mode is required for DTLS if not enabled,
and coaps:// has been requested.
[Lower libcoap library will still error and report this condition]

bc9d1a65d7 Update component/coap to libcoap version release-4.2.0
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)

821c70f5d7 examples: Standardise naming of files, symbols, etc. in examples
* Use "example" in all example function & variable names,
  ie use i2c_example_xxx instead of i2c_xxx for example functions.
  Closes  https://github.com/espressif/esp-idf/issues/198
* Mark example functions, etc. static
* Replace uses of "test" & "demo" with "example"
* Split the UART example into two
* Rename "main" example files to end with "_main.c" for disambiguation

4813ab2d28 examples: check return value of nvs_flash_init
nvs_flash_init may return an error code in some cases, and applications
should check this error code (or at least assert on it being ESP_OK, to
make potential issues more immediately obvious).

This change modifies all the examples which use NVS to check the error
code. Most examples get a simple ESP_ERROR_CHECK assert, while NVS
examples, OTA example, and NVS unit tests get a more verbose check which
may be used in real applications.
