96a4435be1 stm32/boards/STM32F769DISC: Add config to use external SPI as filesys.
This board now has the following 3 build configurations:
- mboot + external QSPI in XIP mode + internal filesystem
- mboot + external QSPI with filesystem (the default)
- no mboot + external QSPI with filesystem

30501d3f54 drivers, stm32: Support SPI/QSPI flash chips over 16MB.
With a SPI flash that has more than 16MB, 32-bit addressing is required
rather than the standard 24-bit.  This commit adds support for 32-bit
addressing so that the SPI flash commands (read/write/erase) are selected
automatically depending on the size of the address being used at each
operation.

b72cb0ca1b py/mpthread.h: Use strong type for mp_thread_set_state() argument.
This modifies the signature of mp_thread_set_state() to use
mp_state_thread_t* instead of void*.  This matches the return type of
mp_thread_get_state(), which returns the same value.

`struct _mp_state_thread_t;` had to be moved before
`#include <mpthreadport.h>` since the stm32 port uses it in its
mpthreadport.h file.

a542c6d7e0 stm32/powerctrl: For F7, allow PLLM!=HSE when setting PLLSAI to 48MHz.
PLLM is shared among all PLL blocks on F7 MCUs, and this calculation to
configure PLLSAI to have 48MHz on the P output previously assumed that PLLM
is equal to HSE (eg PLLM=25 for HSE=25MHz).  This commit relaxes this
assumption to allow other values of PLLM.

888ddb81dd py/emitnative: Stop after finding an unwind target.
The loop searches backwards for a target, but doesn't stop after finding
the first result, meaning that it'll always end up at the outermost
exception handler.

0de304e7da py/emitnative: Use NULL for pending exception (not None).
This previously made the native emitter incompatible with the bytecode
emitter, and mp_resume (and subsequently mp_obj_generator_resume) expects
the bytecode emitter behavior (i.e. throw==NULL).

1f4b607116 tests: Add tests for generator throw and yield-from with exc handlers.
This commit adds a generator test for throwing into a nested exception, and
one when using yield-from with a pending exception cleanup.  Both these
tests currently fail on the native emitter, and are simplified versions of
native test failures from uasyncio in #5332.

d89ed3e62b unix/unix_mphal: Add compile check for incompatible GIL+ASYNC_KBD_INTR.
It is not safe to enable MICROPY_ASYNC_KBD_INTR and MICROPY_PY_THREAD_GIL
at the same time.  This will trigger a compiler error to ensure that it
is not possible to make this mistake.

fee7e5617f unix: Release GIL during all system calls.
Addition of GIL EXIT/ENTER pairs are:

- modos: release the GIL during system calls.  CPython does this as well.

- moduselect: release the GIL during the poll() syscall.  This call can be
  blocking, so it is important to allow other threads to run at this time.

- modusocket: release the GIL during system calls.  Many of these calls can
  be blocking, so it is important to allow other threads to run.

- unix_mphal: release the GIL during the read and write syscalls in
  mp_hal_stdin_rx_chr and mp_hal_stdout_tx_strn.  If we don't do this
  threads are blocked when the REPL or the builtin input function are used.

- file, main, mpconfigport.h: release GIL during syscalls in built-in
  functions that could block.

96716b46e1 unix/Makefile: Reserve CFLAGS_EXTRA/LDFLAGS_EXTRA for external use.
When CFLAGS_EXTRA/LDFLAGS_EXTRA (or anything) is set on the command line of
a make invocation then it will completely override any setting or appending
of these variables in the makefile(s).  This means builds like the coverage
variant will have their mpconfigvariant.mk settings overridden.  Fix this
by using CFLAGS/LDFLAGS exclusively in the makefile(s), reserving the
CFLAGS_EXTRA/LDFLAGS_EXTRA variables for external command-line use only.

d9433d3e94 py/obj.h: Add and use mp_obj_is_bool() helper.
Commit d96cfd13e3 introduced a regression in
testing for bool objects, that such objects were in some cases no longer
recognised and bools, eg when using mp_obj_is_type(o, &mp_type_bool), or
mp_obj_is_integer(o).

This commit fixes that problem by adding mp_obj_is_bool(o).  Builds with
MICROPY_OBJ_IMMEDIATE_OBJS enabled check if the object is any of the const
True or False objects.  Builds without it use the old method of ->type
checking, which compiles to smaller code (compared with the former
mentioned method).

Fixes #5538.

edbb73a411 py/qstr: Don't include or init qstr_mutex when GIL is enabled.
When threads and the GIL are enabled, then the qstr mutex is not needed.
The qstr_mutex field is never used in this case because of:

    #if MICROPY_PY_THREAD && !MICROPY_PY_THREAD_GIL
    #define QSTR_ENTER() mp_thread_mutex_lock(&MP_STATE_VM(qstr_mutex), 1)
    #define QSTR_EXIT() mp_thread_mutex_unlock(&MP_STATE_VM(qstr_mutex))
    #else
    #define QSTR_ENTER()
    #define QSTR_EXIT()
    #endif

So, we can completely remove qstr_mutex everywhere when MICROPY_PY_THREAD
&& !MICROPY_PY_THREAD_GIL.

ccc18f047d py/gc: Don't include or init gc_mutex when GIL is enabled.
When threads and the GIL are enabled, then the GC mutex is not needed.  The

    #define GC_ENTER() mp_thread_mutex_lock(&MP_STATE_MEM(gc_mutex), 1)
    #define GC_EXIT() mp_thread_mutex_unlock(&MP_STATE_MEM(gc_mutex))
    #else
    #define GC_ENTER()
    #define GC_EXIT()
    #endif

So, we can completely remove gc_mutex everywhere when MICROPY_PY_THREAD
&& !MICROPY_PY_THREAD_GIL.

6db5cede06 tools/pydfu.py: Clean up syntax, update comments and docstrings.
Some parts of code have been aligned to increase readability.  In general
'' instead of "" were used wherever possible to keep the same convention
for entire file.  Import inspect line has been moved to the top according
to hints reported by pep8 tools.  A few extra spaces were removed, a few
missing spaces were added.  Comments have been updated, mostly in
"read_dfu_file" function.  Some other comments have been capitalized and/or
slightly updated.  A few docstrings were fixed as well.  No real code
changes intended.

599371b133 windows: Support word-based move/delete key sequences for REPL.
Translate common Ctrl-Left/Right/Delete/Backspace to the EMACS-style
sequences (i.e. Alt key based) for forward-word, backward-word, forwad-kill
and backward-kill.  Requires MICROPY_REPL_EMACS_WORDS_MOVE to be defined so
the readline implementation interprets these.

c14ff6194c esp8266/modules: Fix AttributeError in _boot.py if flash not formatted.
Prior to this commit, if the flash filesystem was not formatted then it
would error: "AttributeError: 'FlashBdev' object has no attribute 'mount'".
That is due to it not being able to detect the filesystem on the block
device and just trying to mount the block device directly.

This commit fixes the issue by just catching all exceptions.  Also it's not
needed to try the mount if `flashbdev.bdev` is None.

integer is not negative.

40057600b8 py/obj: Optimise mp_obj_get_type for immediate objs with repr A and C.
This function is called often and with immediate objects enabled it has

is now slightly faster with immediate objects enabled than with them
disabled.

d96cfd13e3 py/obj: Add MICROPY_OBJ_IMMEDIATE_OBJS option to reduce code size.
This option (enabled by default for object representation A, B, C) makes
None/False/True objects immediate objects, ie they are no longer a concrete
object in ROM but are rather just values, eg None=0x6 for representation A.

Doing this saves a considerable amount of code size, due to these objects
being widely used:

   bare-arm:  -392 -0.591%
minimal x86:  -252 -0.170% [incl +52(data)]
   unix x64:  -624 -0.125% [incl -128(data)]
unix nanbox:    +0 +0.000%
      stm32: -1940 -0.510% PYBV10
     cc3200: -1216 -0.659%
    esp8266:  -404 -0.062% GENERIC
      esp32:  -732 -0.064% GENERIC[incl +48(data)]
        nrf:  -988 -0.675% pca10040
       samd:  -564 -0.556% ADAFRUIT_ITSYBITSY_M4_EXPRESS

6f0c83f6e1 py/obj.h: Redefine qstr object encoding to add immediate obj encoding.
This commit adjusts the definition of qstr encoding in all object
representations by taking a single bit from the qstr space and using it to
distinguish between qstrs and a new kind of literal object: immediate
objects.  In other words, the qstr space is divided in two pieces, one half
for qstrs and the other half for immediate objects.

There is still enough room for qstr values (29 bits in representation A on
a 32-bit architecture, and 19 bits in representation C) and the new
immediate objects can be used for things like None, False and True.

339d0816c5 py/runtime: Move MICROPY_PORT_INIT_FUNC near the end of mp_init().
This moves the MICROPY_PORT_INIT_FUNC hook to the end of mp_init(), just
before MP_THREAD_GIL_ENTER(), so that everything (in particular the GIL
mutex) is intialized before the hook is called.  MICROPY_PORT_DEINIT_FUNC
is also moved to be symmetric (but there is no functional change there).

If a port needs to perform initialisation earlier than
MICROPY_PORT_INIT_FUNC then it can do it before calling mp_init().

853aaa06f2 lib/mp-readline: Add word-based move/delete EMACS key sequences.
This commit adds backward-word, backward-kill-word, forward-word,
forward-kill-word sequences for the REPL, with bindings to Alt+F, Alt+B,
Alt+D and Alt+Backspace respectively.  It is disabled by default and can be
enabled via MICROPY_REPL_EMACS_WORDS_MOVE.

Further enabling MICROPY_REPL_EMACS_EXTRA_WORDS_MOVE adds extra bindings
for these new sequences: Ctrl+Right, Ctrl+Left and Ctrl+W.

The features are enabled on unix micropython-coverage and micropython-dev.
