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.

0cf03bd3b1 zephyr: Use CONFIG_USB_DEVICE_STACK for conditional USB device support.
CONFIG_USB was removed in Zephyr v2.7.0 after some Kconfig rework that
made it sufficient to use CONFIG_USB_DEVICE_STACK only.

de43b500bd py/runtime: Allow initialising sys.path/argv with defaults.
If MICROPY_PY_SYS_PATH_ARGV_DEFAULTS is enabled (which it is by default)
then sys.path and sys.argv will be initialised and populated with default
values.  This keeps all bare-metal ports aligned.

80e79a777d zephyr: Add initial ubluetooth module integration.
Currently only advertising and scanning are supported, using the ring
buffer for events (ie not synchronous events at this stage).

The ble_gap_advertise.py multi-test passes (tested on a nucleo_wb55rg
board).

f17c0db5f7 zephyr: Update disk access configuration for Zephyr v2.6.0.
Zephyr's Kconfig symbols and defaults for SDHC/SDMMC disk drivers and
the disk access subsystem were reworked between Zephyr v2.5.0 and
v2.6.0. Update MicroPython accordingly.

d120859857 zephyr: Run scheduled callbacks at REPL and during mp_hal_delay_ms.
And ctrl-C can now interrupt a time.sleep call.  This uses Zephyr's k_poll
API to wait efficiently for an event signal, and an optional semaphore.

ac94e06f0b zephyr: Include storage/flash_map.h unconditionally.
Include storage/flash_map.h unconditionally so we always have access to the
FLASH_AREA_LABEL_EXISTS macro, even if CONFIG_FLASH_MAP is not defined.

This fixes a build error for the qemu_x86 board:

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.

4837b1caa2 zephyr: Convert DT_FLASH_AREA usages to new dts macros.
Converts DT_FLASH_AREA usages in the zephyr port to new device tree macros
introduced in zephyr 2.3.

84fa3312cf all: Format code to add space after C++-style comment start.
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //

110a610f70 zephyr: Execute main.py file if it exists.
Adds support in the zephyr port to execute main.py if the file system is
enabled and the file exists. Existing support for executing a main.py
frozen module is preserved, since pyexec_file_if_exists() works just
like pyexec_frozen_module() if there's no vfs.

78c7e4a859 zephyr: Enable usb mass storage class on mimxrt1050_evk.
Enables the zephyr usb device stack and mass storage class on the
mimxrt1050_evk board. The mass storage class is backed by the sdhc disk
access driver, so it's now possible to browse and modify the contents of
the SD card from a USB host (your PC). This is in preparation to support
writing a main.py script to the SD card, and then executing it after the
next reset.

5feb54afbb zephyr: Mount a file system during init.
Adds support in the zephyr port to mount a file system if a block device
(sdhc disk access or flash area) is available. The mount point is either
"/sd" or "/flash" depending on the type of block device.

Tested with an sdhc disk access block device and fatfs on the
mimxrt1050_evk board.

Tested with a flash area block device and littlefs on the reel_board.

53f3cbc2c4 zephyr/main: Use mp_stack API instead of local pointer for stack top.
The MP_STATE_THREAD(stack_top) is always available so use it instead of
creating a separate variable.  This also allows gc_collect() to be used as
an independent function, without real_main() being called.

a3dc1b1957 all: Remove inclusion of internal py header files.
Header files that are considered internal to the py core and should not
normally be included directly are:
    py/nlr.h - internal nlr configuration and declarations
    py/bc0.h - contains bytecode macro definitions
    py/runtime0.h - contains basic runtime enums

Instead, the top-level header files to include are one of:
    py/obj.h - includes runtime0.h and defines everything to use the
        mp_obj_t type
    py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
        and defines everything to use the general runtime support functions

Additional, specific headers (eg py/objlist.h) can be included if needed.
