Move sched/task/task/task_gettid.c to libs/libc/unistd/lib_gettid.c. gettid() is a dumb wrapper around getpid(). It is wasteful of resources to support TWO systme calls, one for getpid() and one for gettid(). Instead, move gettid() in the C library where it calls the single sysgtem call, getpid(). Much cleaner.
This adds support for the Q10 BlackBerry based keyboard
from Solder Party. https://www.solder.party/docs/keyboard-pmod/
They keyboard device registered at /dev/kbdN is fully compatible
with hidkbd and has been testing with the Keyboard FeatherWing
on the nRF52 platform.
The buttons are added as a standard discrete joystick if
optionally enabled. The PMOD variant of this does not
include these buttons, but the Keyboard FeatherWing does.
This joystick is usually defined at /dev/djoyN and
can be used with the djoy example application.

The WS2812 is very common in LED strips as it is an integrated
controller and LED. It is driven by a single data line, but
the timing requirements can be met by using most SPI controllers
and the use of DMA.
This driver has been validated on the nRF52 arch both with a
single LED and a strip of 144.

Summary:
- ARCH_GLOBAL_IRQDISABLE was initially introduced for LC823450 SMP
- At that time, i.MX6 (quad Cortex-A9) did not use this config
- However, this option is now used for all CPUs which support SMP
- So it's good timing for refactoring the code
Impact:
- Should have no impact because the logic is the same for SMP
Testing:
- Tested with board: spresense:smp, spresense:wifi_smp
- Tested with qemu: esp32-core:smp, maix-bit:smp, sabre-6quad:smp
- Build only: lc823450-xgevk:rndis, sam4cmp-db:nsh

https://linux.die.net/man/2/epoll_ctl:
EPOLLONESHOT (since Linux 2.6.2)
Sets the one-shot behavior for the associated file descriptor.
This means that after an event is pulled out with epoll_wait(2)
the associated file descriptor is internally disabled and
no other events will be reported by the epoll interface.
The user must call epoll_ctl() with EPOLL_CTL_MOD to
rearm the file descriptor with a new event mask.

Linux Programmer's Manual
NAME
epoll_create, epoll_create1 - open an epoll file descriptor
...
SYNOPSIS
#include <sys/epoll.h>
int epoll_create1(int flags);
...
epoll_create1()
If flags is 0, then, other than the fact that the obsolete
size argument is dropped, epoll_create1() is the same as
epoll_create(). The following value can be included in flags
to obtain different behavior:
EPOLL_CLOEXEC
Set the close-on-exec (FD_CLOEXEC) flag on the new file
descriptor. See the description of the O_CLOEXEC flag in
open(2) for reasons why this may be useful.

DESCRIPTION
EPOLL_CTL_DEL

The event argument describes the object linked to the file descriptor
fd. The struct epoll_event is defined as:

void *ptr;
int fd;
uint32_t u32;
uint64_t u64;
} epoll_data_t;
struct epoll_event {

};

Provide functions which get and set the 3A (Auto white balance/Auto
exposure/Auto
focus) parameters.
These are achieved by the ioctl request codes VIDIOC_G_EXT_CTRLS and
VIDIOC_S_EXT_CTRLS which have the following settings:
1. ctrl_class = V4L2_CTRL_CLASS_CAMERA
2. id = V4L2_CID_3A_PARAMETER
Also, provide function which get the 3A adjustment status.
This is achieved by the ioctl request codes VIDIOC_G_EXT_CTRLS which has the
following settings:
1. ctrl_class = V4L2_CTRL_CLASS_CAMERA
2. id = V4L2_CID_3A_STATUS
Fix the following three bugs about ON/OFF control of auto white balance and auto
exposure:
- The returned value of VIDIOC_G_CTRL with id = V4L2_CID_AUTO_WHITE_BALANCE is
different from V4L2 specification.
- Auto exposure is locked if auto white balance lock is requested.
- Auto exposure and auto white balance are locked if auto exposure lock is
requested.
