commit 7354ab187ed701ae041b45a0a6603878ab9b165d and commit
1e2f06718103e7028809012a69b7ac932e9ae537 added code to skip all
remaining channels when the channel number is -1. This adds support for
testing that using the example app. The BL602 driver's first channel is
channel 0, so this also allows the example app to select the first
channel.
commit d8199fe460 changed Kconfig, but it
looks like pwm_main.c should have been changed too. This adds support
for the 5th and 6th channels to the code, and adds an error if more than
6 channels are configured.
commit 36d4bfa774 set a hostname to work
around getaddrinfo failing. getaddrinfo returns a non-zero value on
error, and there should be an early return after the error message is
printed.

void sched_note_string(FAR const char *buf);

FAR const void *buf, size_t len);

void sched_note_bprintf(uint32_t module, uint8_t event,
FAR const char *fmt, ...) printflike(3, 4);

suggestion:
1. add "&" after the command when running this example.
2. must enable SCHED_INSTRUMENTATION_DUMP, and that enable CONFIG_SYSTEM_TRACE can help you view log.
Modulo operation used to calculate digits after decimal point,
but if that result is <10, a leading zero wasn't added, giving a
wrong value.
Same as 34c7bec0dc
but on the example app.

Fix some issues and update license to apache.
- Fails to open the video driver.
- Change format from YUV422 to RGB565,
and add captured image output to LCD.
- An application cannot exit by infinite loop.
- In video-only mode without capturing still images,
do not allocate capture memory for still images to
reduce the memory usage.
format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'off_t' {aka 'long long int'}

following the idea of having a kill \<pid\> that will send SIGTERM default signal to the task,
this example of a "daemon leds" will handle SIGTERM in order to gracefully terminate itself.
It allows to restart this daemon after correctly terminating it.
No mode was set before the first read by the app.
The first time the app was run, it worked properly, reading
temperature and humidity on the first read(). But subsequent reads
returned humidity only since that was last mode set up.
Also, the ioctl read was returning invalid results.

The examples/webserver app can be built in two modes:
(1) in standalone mode, or
(2) as a NSH built-in app.
When run in standalone mode, the webserver program is responsible for
bringing up the network (including DHCP if configured). Also, the
webserver program must never exit, so if httpd fails (i.e., if
httpd_listen() returns), webserver_main() goes into an endless loop.
When run as a NSH built-in app, network bring-up is the responsibility
of other processes and the webserver program assumes the network is
already properly configured when it starts. Also, if httpd_listen()
returns, the webserver program should terminate.
Prior to this change, the webserver program would *not* terminate,
even when running as a NSH built-in app. For example:
nsh> webserver &
webserver [6:100]
nsh> Starting webserver
nsh> kill -9 6
nsh> webserver_main: Still running
nsh> webserver_main: Still running
nsh> webserver_main: Still running
nsh> webserver_main: Still running
The line "webserver_main: Still running" would be forever printed
every 3 seconds, however httpd_listen() is no longer running and the
webserver is not functional.
This change makes the webserver play nicely when running as a NSH
built-in app. With this change applied:
nsh> webserver &
webserver [6:100]
nsh> Starting webserver
nsh> kill -9 6
nsh> webserver_main: Exiting
apps/examples/webserver/webserver_main.c:
* main(): Infer from CONFIG_NSH_BUILTIN_APPS if this is a
standalone program or a NSH built-in app. (See [1], where
similar logic was added to decide whether to do network bring-up
or not.) If standalone, run forever as before. If built-in
app, exit when httpd terminates.

- Fix formatting (a few line breaks and spaces missing).
Because the configured signo may have the default action(e.g. SIGPIPE),
and then will generate the bad side effect before the caller wakeup.

This makes LVGL use malloc/free to handle its memory (instead of
their own memory handling) and supports a tick interface by which
LVGL can ask NuttX the elapsed time, instead of having to periodically
"tick" LVGL internal time in a thread.
since it is wrong to close the builtin stream and specially note
https://pubs.opengroup.org/onlinepubs/9699919799/functions/fclose.html:
Since after the call to fclose() any use of stream results in
undefined behavior, fclose() should not be used on stdin, stdout,
or stderr except immediately before process termination (see XBD
Process Termination), so as to avoid triggering undefined behavior
in other standard interfaces that rely on these streams. If there
are any atexit() handlers registered by the application, such a
call to fclose() should not occur until the last handler is
finishing. Once fclose() has been used to close stdin, stdout, or
stderr, there is no standard way to reopen any of these streams.
and it is also unnecessary because the stream always get flushed.
