Flavio Ceolin b5ca7a06b4 pm: device_runtime: Add delay to async put
Add a delay parameter to asynchronous device runtim put. This allows
to delay the put operation what is useful to avoid multiple states
transitions.

Daniel Leung 0a50ff366e kernel: rename z_current_get() to k_sched_current_thread_query()
The original idea of z_current_get() was to be the counterpart
of k_current_get() when thread local variable for current has
not been initialized if TLS is enabled, otherwise they are
the same function. Now since z_current_get() is being used
outside of core kernel, rename it under kernel namespace so
other subsystem can conceptually use them too.

Keith Packard ced5053e6c subsys/tracing: Use z_current_get in switch_{in,out}
The thread switching tracing hooks are called in the middle of swapping,
before z_thread_entry has a chance to set the z_tls_current value, so they
cannot use k_current_get. Switch them to z_current_get instead.

Gerard Marull-Paretas 79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Andrew Jackson e7e827a0d2 kernel: Use mask rather than boolean to update events
Although there is nothing wrong with the existing code,
it doesn't permit individual bits to be set (or cleared).
This makes further changes slightly awkward.

Use a mask to restrict the bits set in an event.

Peter Mitsis d1353a4584 kernel: pipes: add pipe flush routines
Adds two routines to flush pipe objects:
   k_pipe_flush()
     - This routine flushes the entire pipe. That includes both
     the pipe's buffer and all pended writers. It is equivalent
     to reading everything into a giant temporary buffer which
     is then discarded.
   k_pipe_buffer_flush()
     - This routine flushes only the pipe's buffer (if it exists).
     It is equivalent to reading a maximum of "buffer size" bytes
     into a temporary buffer which is then discarded.

Tom Burdick 97dc88bb6d tracing: Automatic syscall tracing
When generating syscall wrappers, call a tracing macro with the id,
name, and all parameters of the syscall as params when entering and
leaving the syscall. This can be disabled in certain call sites
by defining DISABLE_SYSCALL_TRACING which is useful for certain
tracing implementations which require syscalls themselves to work.

Notably some syscalls *cannot* be automatically traced this way and
headers where exclusions are set are in the gen_syscall.py as notracing.

Includes a systemview and test format implementation.

Tested with systemview, usb, and uart backends with the string
formatter using the tracing sample app.

Debugging the trace wrapper can be aided by setting the TRACE_DIAGNOSTIC
env var and rebuilding from scratch, a warning is issued for every
instance a syscall is traced.

Automatically generating a name mapping for SYSVIEW_Zephyr.txt is a
future item as is documenting how to capture and use the tracing data
generated.

Peter Mitsis ae394bff7c kernel: add support for event objects
Threads may wait on an event object such that any events posted to
that event object may wake a waiting thread if the posting satisfies
the waiting threads' event conditions.

The configuration option CONFIG_EVENTS is used to control the inclusion
of events in a system as their use increases the size of
'struct k_thread'.
