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.
