6b82eb75be zephyr/main: Add /flash/lib or /sd/lib to sys.path on start up.
If there is a filesystem available, this change makes sure there is a "lib"
in `sys.path`, eg so that "mip install" works correctly.

d9b4327c66 zephyr/main: Execute boot.py and main.py like other ports.
Changes here make the zephyr port act the same as other ports for the
start up and shut down sequence:
- `boot.py` is executed if it exists, and can force a soft reset
- `main.py` is only executed if in friendly REPL and if `boot.py` executed
  successfully; and it can also force a soft reset
- print "MPY: " before "soft reboot" on soft reset

f47e214cdc all: Rename the "NORETURN" macro to "MP_NORETURN".
This commit renames the NORETURN macro, indicating to the compiler
that a function does not return, into MP_NORETURN to maintain the same
naming convention of other similar macros.

To maintain compaitiblity with existing code NORETURN is aliased to
MP_NORETURN, but it is also deprecated for MicroPython v2.

This changeset was created using a similar process to
decf8e6a8b ("all: Remove the "STATIC"
macro and just use "static" instead."), with no documentation or python
scripts to change to reflect the new macro name.

6601d4d7eb zephyr: Create ability to use device_next with CDC ACM as REPL.
This enables using the newer USB stack and its CDC ACM for the REPL.

To switch to it, board file must contain `CONFIG_USB_DEVICE_STACK_NEXT=y`
and `CONFIG_USBD_CDC_ACM_CLASS=y`.  In the case of a board that is a
platform that supports the older device stack, `CONFIG_USB_DEVICE_STACK=n`
may be necessary.

Commit 07a8e3253a2d8a2076c9c83c4ed4158fa3fbb2a2 removes
CONFIG_MMC_VOLUME_NAME from the Kconfig space. Instead we need to use
the device tree to find the "disk-name" property of "zephyr,mmc-disk"
devices.

6833f3dda9 zephyr: Add threading support.
This commit implements the `_thread` module on the zephyr port.

Due to the fact that we are still using a rather old version of Zephyr,
`CONFIG_DYNAMIC_THREAD` is not available and therefore the stack for
threads cannot be allocated dynamically, only at compile time.  So for the
time being and for the purpose of this commit, a maximum of 4 Zephyr
threads (besides the main thread) can be created.  Once we manage to update
to the latest version of Zephyr this won't be a problem anymore.

Configuration for the nrf52840dk is added as part of this change, because
this board was used to test the threading support.

The Zephyr option `CONFIG_THREAD_CUSTOM_DATA` is used to enable threading
on a per board basis.  The `thread.conf` file is added as a convenient way
to enable threading.

05cad7b56f zephyr: Remove obsolete tinytest test framework.
Commit f573e73bae rewored the zephyr port to
build MicroPython as a cmake target, and since that commit the
`make-bin-testsuite` helper script no longer works (it requires a Makefile)
and hence the tinytest test framework can no longer be run.

Instead of fixing this, remove the option to use tinytest.  Boards running
zephyr can use the standard `tests/run-tests.py` script to run tests in the
usual way.

decf8e6a8b all: Remove the "STATIC" macro and just use "static" instead.
The STATIC macro was introduced a very long time ago in commit
d5df6cd44a.  The original reason for this was
to have the option to define it to nothing so that all static functions
become global functions and therefore visible to certain debug tools, so
one could do function size comparison and other things.

This STATIC feature is rarely (if ever) used.  And with the use of LTO and
heavy inline optimisation, analysing the size of individual functions when
they are not static is not a good representation of the size of code when
fully optimised.

So the macro does not have much use and it's simpler to just remove it.
Then you know exactly what it's doing.  For example, newcomers don't have
to learn what the STATIC macro is and why it exists.  Reading the code is
also less "loud" with a lowercase static.

One other minor point in favour of removing it, is that it stops bugs with
`STATIC inline`, which should always be `static inline`.

Methodology for this commit was:

1) git ls-files | egrep '\.[ch]$' | \
   xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/"

2) Do some manual cleanup in the diff by searching for the word STATIC in
   comments and changing those back.

3) "git-grep STATIC docs/", manually fixed those cases.

4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

5015779a6f py/builtinevex: Handle invalid filenames for execfile.
If a non-string buffer was passed to execfile, then it would be passed
as a non-null-terminated char* to mp_lexer_new_from_file.

This changes mp_lexer_new_from_file to take a qstr instead (as in almost
all cases a qstr will be created from this input anyway to set the
`__file__` attribute on the module).

This now makes execfile require a string (not generic buffer) argument,
which is probably a good fix to make anyway.

Fixes issue #12522.

94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

6e71cde6aa ports: Use default VFS config for import_stat and builtin_open.
For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.

This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
  nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

5956466c0e py/builtin: Clean up and simplify import_stat and builtin_open config.
The following changes are made:

- If MICROPY_VFS is enabled then mp_vfs_import_stat and mp_vfs_open are
  automatically used for mp_import_stat and mp_builtin_open respectively.

- If MICROPY_PY_IO is enabled then "open" is automatically included in the
  set of builtins, and points to mp_builtin_open_obj.

This helps to clean up and simplify the most common port configuration.

f84145bea1 zephyr: Implement machine.Pin.irq() for setting callbacks on pin change.
Supports hard and soft interrupts.  In the current implementation, soft
interrupt callbacks will only be called when the VM is executing, ie they
will not be called during a blocking kernel call like k_msleep.  And the
behaviour of hard interrupt callbacks will depend on the underlying device,
as well as the amount of ISR stack space.

Soft and hard interrupts tested on frdm_k64f and nucleo_f767zi boards.
