Add DTLS support to libcoap using TinyDTLS
As TinyDTLS is already a submodule to libcoap, adding in DTLS support is straightforward, but only supports PSK at this point in time. components/coap/CMakeLists.txt: components/coap/component.mk: Add in the new files that have to be built components/coap/Makefile.projbuild: Update the compiler options with -DESPIDF_VERSION components/coap/libcoap: Update the version to include the correct version of tinydtls submodule components/coap/port/dtls_prng.c: components/coap/port/include/coap/dtls_config.h: New port files for DTLS components/coap/port/include/coap_config_posix.h: Include building with TinyDTLS examples/protocols/coap_client/README.md: examples/protocols/coap_client/main/Kconfig.projbuild: examples/protocols/coap_client/main/coap_client_example_main.c: Update CoAP client to support DTLS examples/protocols/coap_server/README.md: examples/protocols/coap_server/main/Kconfig.projbuild: examples/protocols/coap_server/main/coap_server_example_main.c: Update CoAP server to support DTLS See Issue espressif#1379
