File offset actually varies on a per-file-descriptor basis,
and not with the resource that is abstracted behind the file
descriptor.
This is consistent with both the POSIX model and also the
ISO C/C++ model, so Zephyr should follow suit.
This is very work-around-y, but it's necessary to ensure
that shared memory objects, block devices, files and
directories all behave consistently.

Add a mode field for struct fd_entry, as well as a new
initializer, z_finalize_typed_fd().
The constants ZVFS_MODE_* may be used to differentiate
between fifo, character device, message queues, directories,
semaphores, block devices, shared memory objects, regular files,
symbolic links, and sockets.

Mark mlockall() and munlockall() as supported, as well as the
_POSIX_MEMLOCK Option.
These functions are currently expected to fail, but are

Add support for mlockall() and munlockall(). These two functions
comprise the _POSIX_MEMLOCK Option which is required by PSE51,
PSE52, PSE53, and PSE54.
Zephyr's on-demand paging API does not yet support pinning and
unpinning *all* virtual memory regions, so these functions are
expected to fail, setting errno to ENOSYS. Any other usage is
currently categorized as undefined behaviour.

Move the zvfs_ftruncate() call from fs.c to fdtable.c, as file

With many tests having 10s or scenarios and variants, anytime we make a
change to a test right now, we end up building all scenarios on all
platforms which ends up in multiple 10s of the thousands of instances
that need to run on 30 or 40 runners blocking CI for hours. We do not
really need that, a test needs to be smart about its coverage and not
rely on boiling the ocean to catch, mostly build errors that are
platform specific.
Change this to do the normal coverage we get on push events.

Extern declaration of __stack_chk_guard added volatile to
the type while the declaration was non-volatile. This cause
type check errors with compilers that declares the
__stack_chk_guard variable in an internal pre-include
header file (IAR).
While I think the volatile keyword is unnecessary, I decided
on keep it and add it to the declaration in
kernel/compiler_stack_protect.c

The LL_EXTENSION_SYMBOL macro is used to export a symbol to the base
image. When CONFIG_LLEXT is not defined, or the file is being compiled
outside of an llext, the macro is not useful and would leave orphan
sections in the final image instead.
This patch adds the LL_EXTENSION_BUILD definition to the llext build
process, and uses it to stub out the symbol-defining macro when not
building an llext.

There are some compatibilty situations where carriage return does not
work (e.g. on Serial Monitor in VSCode). Moreover, keeping the

in this case.
