RTP Tools is a set of small applications that can be used for
processing RTP data. This application is able to receive RTP
packets and write the content to a FIFO. `nxplayer` then reads
from the FIFO, enabling using NuttX as a RTP receiver for audio
applications.
This is particularly useful to stream uncompressed audio through
Wi-Fi to remote speakers.
The defconfigs that test PSRAM on ESP32 contain the `ramtest` app,
but it doesn't test the memory correctly as it try to access the
memory directly. The memory, however, is being used by the system's
heap and `ramtest` can mess with it. Therefore, it makes sense to
test using `mm` testing app.
If TELNET_CHARACTER_MODE is set, the ECHO must be handled by the telnet server.
So this option is useless. We need a new approach to control the ECHO behavior.

This commit adds support to Ai-Thinker ESP32 Audio Kit V2.2 A247
board.
There are two modules of this board. The old model uses AC101 audio
and is not supported currently (AFAIK there is no AC101 driver) and
the new version uses the ES8388 audio codec. This model is supported
by this commit.
Just read the documentation to test playing an audio file.
TODO: Test audio recording.
* Remove the 'COEXISTENCE' suffix from Wi-Fi's STA + SoftAP mode.
Coexistence usually refers to Wi-Fi + BLE, instead of Wi-Fi's
operation mode;
* Remove commented debug code;
* Remove outdate function descriptions;
These are basically the same from the esp32-devkitc board. As the
defconfigs do not make use of any board-specific peripheral, there
is no need to duplicate them in every ESP32 board.

MCUboot support is no longer behind EXPERIMENTAL for the following
chips:
- ESP32
- ESP32-S2
- ESP32-S3
- ESP32-C3

* enable DLFCN.
* bump WAMR to a version which i happened to test.
* enable bulk-memory because it's required by recent versions of
wasi-sdk, which i happened to use to build a test module.
(test.wasm in the log below.)
Lightly tested with a stripped down version of WAMR native-lib example. [1]

* disable too verbose wamr options.
* enable CONFIG_SCHED_WAITPID. because async execution on nsh prompt
sometimes confuses me.
* enable toywasm. it's sometimes convenient to have another interpreter.
note: wasm3 in nuttx apps doesn't have wasi enabled.
