0a7c308f1b examples/pwm: Fix PWM range 
This commit fixes the overflow that happens when setting the duty cycle to 100% in the PWM example.
It now correctly passes the value 0xffff rather than 0x0000 when setting the duty cycle to 100 and makes sure that no underflow happens when setting the duty cycle to 0.

6b720033cc examples/mqttc: Check for MQTT ACK and avoid passing '\0' 
This patch will force wait for MQTT ACK (connection) and also
fix the issue caused by "strlen(mqtt_cfg.msg) + 1" that will
include the "\0" in the payload. It's forbidded by MQTT spec.

Some MQTT servers will ignore it, others like TagoIO will refuse
the packet.

0a9b983e90 apps/examples/pipe: check POSIX-compliant behavior of NuttX's FIFOs 
Adjust the test considering the POSIX-compliant behavior of the
NuttX's FIFO (mkfifo), which should block `open` for read-only
and write-only. This test's result is expected to be the same with
any other POSIX-compliant system.

This commit also:

 * Fix redirect test;
 * Use pthread instead `task_create` to be able to run this test
on POSIX-compliant systems;
 * General fixes regarding formatting and error messages;

4f11f38c38 interpreters/wamr: add compile role of WebAssembly 
Add compilation rules to support WebAssembly(WASM/WAMR):

1. Compile Toolchain
 1> Download WASI sdk and export the WASI_SDK_PATH path:

$ wget https://github.com/WebAssembly/wasi-sdk/releases/download/wasi-sdk-19/wasi-sdk-19.0-linux.tar.gz
$ tar xf wasi-sdk-19.0-linux.tar.gz
Put wasi-sdk-19.0 to your host WASI_SDK_PATH environment variable, like:
$ export WASI_SDK_PATH=`pwd`/wasi-sdk-19.0

 2> Download Wamr "wamrc" AOT compiler and export to the PATH:
$ mkdir wamrc
$ wget https://github.com/bytecodealliance/wasm-micro-runtime/releases/download/WAMR-1.1.2/wamrc-1.1.2-x86_64-ubuntu-20.04.tar.gz
$ tar xf wamrc-1.1.2-x86_64-ubuntu-20.04.tar.gz
$ export PATH=$PATH:$PWD

2. Configuring and running

 1> Configuring sim/wamr and compile:

nuttx$ ./tools/configure.sh  sim/wamr
nuttx$ make
...
Wamrc Generate AoT: /home/archer/code/nuttx/n5/apps/wasm/hello.aot
Wamrc Generate AoT: /home/archer/code/nuttx/n5/apps/wasm/coremark.aot
LD:  nuttx

 2> Copy the generated wasm file(Interpreter/AoT)

nuttx$ cp ../apps/wasm/hello.aot .
nuttx$ cp ../apps/wasm/hello.wasm .
nuttx$ cp ../apps/wasm/coremark.wasm .

 3> Run iwasm

nuttx$ ./nuttx
NuttShell (NSH) NuttX-10.4.0
nsh> iwasm /data/hello.wasm

c57e7a7b81 examples/lvglterm: Add LVGL Terminal for NSH 
This PR adds an LVGL App that executes NSH Commands (entered with a Touchscreen Keyboard) and renders the NSH Output. The app follows the same design as the `lvgldemo` app and is explained here: ["NuttX RTOS for PinePhone: LVGL Terminal for NSH Shell"](https://lupyuen.github.io/articles/terminal)

`examples/README.md`: Added doc for `lvglterm` app

`examples/lvglterm/lvglterm.c`: LVGL Terminal App

`examples/lvglterm/Makefile`, `Make.defs`: Makefile for LVGL Terminal

`examples/lvglterm/Kconfig`: Added menuconfig option for "Application Configuration > Examples > LVGL Terminal"

757fc307c3 examples/lvgldemo: Select default demo 
The LVGL Example App `lvgldemo` currently requires 1 argument: the name of the demo to show.

```bash
lvgldemo widgets
```

In this PR, we propose to make the argument optional if there is only one demo configured. This will enable PINE64 PinePhone to boot straight into `lvgldemo` and auto-start the LVGL App, without entering any `nsh` commands.

### Modified Files

`examples/lvgldemo/lvgldemo.c`: If no arguments are specified and only 1 demo exists, select the demo

Reference:

RECV(2)

NAME
       recv, recvfrom, recvmsg - receive a message from a socket
...
RETURN VALUE
...
       When a stream socket peer has performed an orderly shutdown,
       the return value will be 0 (the traditional "end-of-file" return).

       Datagram sockets in various domains (e.g., the UNIX and Internet domains)
       permit zero-length datagrams.  When such a datagram is received, the return value is 0.
