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.

* It doesn't make much sense to have the default values for
these highly environment-dependent settings.
* netutils/netinit/netinit_associate.c calls wpa_driver_wext_associate
if the SSID is not empty. Depending on the environment, it can take
long to fail. It slows down the boot of some configurations
considerably. eg. esp32-devkitc:wapi
wget is missing from some system (like macOS and Windows native),
it's better to use curl to simplify build environment.

the audio driver may config a very large buffer count,
so let's adjust the message queue length dynamically.

Summary:
- stdin/stdout/stderr are now preallocated in libc and fs_fd
in file_struct are also initialized to -1
- So we need to call fdopen() for stdin again as we did before.
- Also, cn_outstream and cn_errstream are not needed to be set.
- See apps/nshlib/nsh_console.h as well
Impact:
- nsh_usbconsole.c only
Testing:
- Tested with stm32f4discovery:usbnsh

The following nxstyle error is intentionally left.
It's a nested function. I guess nxstyle doesn't support it.
netutils/chat/chat.c:110:8: error: Bad comment alignment
- Fix bug for multiple PWM outputs (CONFIG_PWM_MULTICHAN). Wrong define
was in use and only the information about the first channel was shown.
- Fix formatting (a few line breaks and spaces missing).
