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 DRAM .data size: 14796 bytes 14796 DRAM .bss size: 23560 bytes 23680 -120 Used static DRAM: 38356 bytes ( 142380 available, 21.2% used) 38476 -120 ( +120 available, +0 total) Used static IRAM: 89045 bytes ( 42027 available, 67.9% used) 89045 ( +0 available, +0 total) Flash code: 554231 bytes 563823 -9592 Flash rodata: 179000 bytes 181224 -2224 Total image size:~ 860632 bytes (.bin may be padded larger) 872568 -11936 This commit moves relevant config options to CoAP specific examples and also adds some run time warnings if they are kept disabled.
