ca17315d7f pcie: endpoint: Add public APIs for PCIe endpoint driver
Add public APIs for PCIe endpoint driver:
- EP configuration space read/write
- Mapping/Unmapping of Host buffer and PCIe outbound region
- Raise interrupt to Host
These are minimal base APIs to make PCIe EP functional.

Also, add a Kconfig and an empty CMakeLists.txt for drivers to extend.

8c29aa9881 net: mqtt: Constify utf8 pointer in mqtt_utf8 struct
mqtt_utf8 structure is used to store the client_id, user_name, password,
topic, will_message.
There is no reason for the mqtt code to modify such data, therefore we
can constify the utf8 pointer.

This would also means that theses client, topic, ... strings can be
safely stored in ROM.

fe74218956 sys: util.h: remove template implementation of ARRAY_SIZE
This was added because GNU G++ doesn't support the built-in function
used to produce a compile-time error when invalid parameters are
passed to the macro imlementation.  The template implementation does
not work on declarations like this:

  mytype array[] = { ... }

because it requires an explicit size for the template parameter.

Remove the template specialization, and support C++ with a version of
the macro that doesn't involve references to undefined builtins.

378024c510 userspace: add z_is_in_user_syscall()
Certain types of system call validation may need to be pushed
deeper in the implementation and not performed in the verification
function. If such checks are only pertinent when the caller was
from user mode, we need an API to detect this situation.

This is implemented by having thread->syscall_frame be non-NULL
only while a user system call is in progress. The template for the
system call marshalling functions is changed to clear this value
on exit.

A test is added to prove that this works.

99c2d2d047 kernel/queue: Remove interior use of k_poll()
The k_queue data structure, when CONFIG_POLL was enabled, would
inexplicably use k_poll() as its blocking mechanism instead of the
original wait_q/pend() code.  This was actually racy, see commit
b173e4353f.  The code was structured as a condition variable: using
a spinlock around the queue data before deciding to block.  But unlike
pend_current_thread(), k_poll() cannot atomically release a lock.

A workaround had been in place for this, and then accidentally
reverted (both by me!) because the code looked "wrong".

This is just fragile, there's no reason to have two implementations of
k_queue_get().  Remove.

Note that this also removes a test case in the work_queue test where
(when CONFIG_POLL was enabled, but not otherwise) it was checking for
the ability to immediately cancel a delayed work item that was
submitted with a timeout of K_NO_WAIT (i.e. "queue it immediately").
This DOES NOT work with the origina/non-poll queue backend, and has
never been a documented behavior of k_delayed_work_submit_to_queue()
under any circumstances.  I don't know why we were testing this.

Fixes #25904
