This commit adds documentation to the almost empty `calib_udelay` page
as part of #11081. It provides reasoning for the example, an explanation
of what it does and why `CONFIG_BOARD_LOOPSPERMSEC` is necessary, and
also shows some example console output of the program.

This commit provides documentation for using the `bmp280` application to

This patch will report events in the following scenarios:
1. Events that have changed but not been waited for before being added to
the interest list.
2. Events that occur after `epoll_wait()` returns and before it is called
again.

The functions `hw_write_masked` and `hw_xor_bits` (as defined in
pico-sdk) were defined in NuttX twice.
Additionally these definitions were in conflict (one lacked the
`volatile` modifier).
Now these functions and their dependencies are defined in a new header
file.
Its name is based on the filename of the original definition in
pico-sdk:
src/rp2_common/hardware_base/include/hardware/address_mapped.h
This change should fix the potential issue of GPIO operations failing
due to compiler optimizations caused by the absence of `volatile`.

In certain cases, when the event-wait thread is awakened,
it needs to know the specific mask bit that triggered it,
so that it can branch to different paths accordingly.
This patch introduces the nxevent_getmask function to address this requirement.

Change:
Replace list_delete_init() with list_delete() in nxevent_post.
Reason:
PR 16933 removed list_delete() in nxevent_wait() and allow other task
to preempt event-wait thread after list_add_tail() option, the even-post thread
can preempt it at this time and do list_delete_init().
The problem is that list_delete_init() will make list_in_list() return true, so
DEBUGASSERT(!list_in_list(&(wait->node))); will fail in nxevent_wait() after the event-wait thread
returns.

This code owner file is auto-generated by the Python script in tools/
based off the git logs. It will allow new contributors to get better
auto-suggestions for which reviewers to request on their PRs. It also
creates an easy way to track down authors of certain NuttX subsystems
when refactors/changes are to be made.

There are cases that users do not want the event wait object to be allocated automatically
in the stack as a temporary varialbe in nxevent_tickwait, since multiple threads will
access the varialbe, they want to allocate the object as a global variable for safety
control or easy debug. To solve this problem, this patch add a new function nxevent_tickwait_wait
implementation to give user the chance to pass the global wait object to it.

The nxsig_dispatch should just deliver the signal to either a
thread by pid (tid) or to the process (group) by pid.
Simplify the code so that the intent is more obvious.

The signal dispatch is called from interrupt handlers as well, so
this_task() is wrong. The thread to which the signal is supposed to
be delivered is known (stcb), use that.

On a system with multiple CPU cores, when the system is powered on,
multiple cores may start running simultaneously. In this case, software
is required to handle the startup logic for multi-core synchronization.
One approach is to use global variables.
however, the global variable region may not have been initialized yet.
In such scenarios, we can use a busywait flag to
implement the synchronization strategy.
