esp2020r1 toolchain includes a nano.specs file, which instructs GCC to
substitute libc.a with libc_nano.a.
In the build system, this simplifies handling of the nano formatting
option, eliminating LIBC and LIBM global variables.
If BLK2 is empty then it's OK to continue with a warning (otherwise it may spook users into thinking
something this is wrong, but this is the expected workflow.)
If BLK2 is not empty and doesn't match then we need to fail because it won't be possible to
trust the signature.
The transport segmented TX nack and seg_pending fields must be at least
6 bits to avoid overflow for 32 segment messages. This change rearranges
the seg_tx fields to gather all state flag fields in one byte, while
making the counter fields whole bytes.
Ensures that friend messages are enqueued, even if the packet is
received with an appkey is unknown to the friend. Previously, sdu_recv
would return EINVAL if the appkey was unknown, which would prevent the
lower transport layer from adding the packet to the friend queue. This
is irrelevant for the logic in lower transport, and should not be
returned as an error.
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.

Previous implementation violated the RFC by having both the actual opcode and WS_FIN flag set for all fragments of a message.
Fixed by setting the opcode only for the first fragment and WS_FIN for the last one
Closes IDFGH-2938

Since the scripts of CI will bypass common_components when
trying to get ALL_EXAMPLES, and these BLE Mesh components
will only be used by other mesh examples, i.e. no need to
be compiled as a single example, so we rename the folder
to common_componnets.
