Using the interrupt pipe is recommended in the Get_Report
request section of the HID standard. This option has been
added to support some keyboards that refuse to return valid
keys when polled using the Get_Report request. Support for
the Caps Lock key, including LED, has also been added.
According to RFC 2525, Section 2.17:
"When an application closes a connection in such a way that it can no longer read any received data, the TCP SHOULD, per section 4.2.2.13 of RFC 1122, send a RST if there is any unread received data, or if any new data is received."
When our TCP socket is closed (even when the thread has exited), the peer can keep sending data and NuttX keeps replying ACK (we've tried for ~12h). This is not a good behavior (also different from Linux), so send RST instead of ACK for data receiving in FIN_WAIT.

Problem:
A SOCK_CTRL socket may be led to udp_pollsetup but never reaches
udp_pollteardown, it seems that we shouldn't call udp_pollsetup for
other socket types.

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.
Support mirror display by X/Y axis, it's useful for
single portrait/landscape but need to mirror specific direction.

Refer to issue #8867 for details and rational.
Convert sigset_t to an array type so that more than 32 signals can be supported.
Why not use a uin64_t?
- Using a uin32_t is more flexible if we decide to increase the number of signals beyound 64.
- 64-bit accesses are not atomic, at least not on 32-bit ARMv7-M and similar
- Keeping the base type as uint32_t does not introduce additional overhead due to padding to achieve 64-bit alignment of uin64_t
- Some architectures still supported by NuttX do not support uin64_t
types,
Increased the number of signals to 64. This matches Linux. This will support all xsignals defined by Linux and also 32 real time signals (also like Linux).
This is is a work in progress; a draft PR that you are encouraged to comment on.
In the last change, the assert behavior test was not considered. Therefore, in this change, sync will be performed only when SYS_RESTART/SYS_DOWN situation occurs, avoiding unpredictable results caused by handling locks or semaphores in interrupts.
Calling syslog to print logs in clock_gettime will cause the system to have recursive output, i.e., clock_gettime->sinfo->syslog->clock_gettime, with the consequences of stack overflow or non-stop log output.
