Instead of using Espressif's emulated NVS to save Wi-Fi data, use
`wapi`s wireless configure initialization mechanism for saving
Wi-Fi data. It 1) avoids creating a specific storage partition
just to save Wi-Fi data (ESP32's storage partition is used
instead); 2) avoids initialization problems of the emulated NVS
when SMP is enabled (the Wi-Fi driver tries to initialize it before
the actual partition is initialized); and 3) enables reconnecting
using `wapi reconnect` command and connect the device automatically
on bringup if `CONFIG_NETUTILS_NETINIT` is selected.
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.

* 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;
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.
In order to turn longjmp context-switch safe, it's necessary
to disable interrupts before modifying windowbase and windowstart.
Otherwise, after a context switch, windowstart and windowbase
would be different, leading to a wrongly set windowstart bit due to
longjmp writing it based on the windowbase before the context switch.
This corrupts the registers at the next window overflow reaching
that wrongly set bit.
*Background:*
This PR is related to an issue first observed on ESP-IDF
https://github.com/espressif/esp-idf/issues/5229 and it was, then,
checked on NuttX using a test application.
*The test application:*
To check if the problem affects ESP32, ESP32-S2 and ESP32-S3 on
NuttX, it was created an application based on:
https://en.cppreference.com/w/c/program/longjmp
The application creates 16 tasks (`#define NUMBER_OF_TASKS 16`)
that implements the following daemon:
```
static int setjmp_longjmp_daemon(int argc, char *argv[])
{
for (int i = 0; i < NUMBER_OF_TASKS * 2; i++)
{
jmp_buf env;
volatile int count = 0;
if (setjmp(env) != UINT16_MAX)
{
foo(&env, ++count);
}
}
sem_post(&g_sem);
return EXIT_SUCCESS;
}
```
The main function also initializes a semaphore to avoid application
exiting before tasks return successfully:
```
sem_init(&g_sem, 0, -NUMBER_OF_TASKS);
```
Finally, the round-robin interval was lowered to 1ms to raise the
chances of the longjmp being interrupted by a context switch
(`CONFIG_RR_INTERVAL=1).
This setup was able to reproduce the problem prior to this patch
being applied.
- Add ioctl method to enable allocating the apb buffer.
- Add RX methods to set data width, sample rate, channels and
for receiving data from the I2S peripheral.
- Update the i2schar defconfig to enable the I2S receiver.
- Add nxlooper defconfig to enable testing the RX interface.
- Add specific bindings on ESP32 bringup to enable nxlooper
to work without the need of any specific codec.
