0e7bfc88c6 all: Use mp_obj_malloc everywhere it's applicable.
This replaces occurences of

    foo_t *foo = m_new_obj(foo_t);
    foo->base.type = &foo_type;

with

    foo_t *foo = mp_obj_malloc(foo_t, &foo_type);

Excludes any places where base is a sub-field or when new0/memset is used.

988827b85a esp32/modesp32: Properly define RTC_VALID_EXT_PINS on S2/S3 variants.

commit defines the valid RTC_VALID_EXT_PINS for the S2/S3 variants,
otherwise, it keeps functionality the same.

The current pull=Pin.PULL_HOLD argument doesn't make a lot of sense in the
context of what it actually does vs what the ESP32 quickref document says
it does.

This commit removes PULL_HOLD and adds a new hold=True|False keyword
argument to Pin()/Pin.init().  Setting this to True will cause the ESP32 to
lock the configuration of the pin – including direction, output value,
drive strength, pull-up/-down – such that it can't be accidentally changed
and will be retained through a watchdog or internal reset.

665f0e2a68 esp32: Sleep one tick in MICROPY_EVENT_POLL_HOOK.
If MicroPython threads are enabled, loops waiting for an incoming event
should release the GIL and suspend, allowing other tasks to run while they
wait.

Prior to this commit, the problem can easily be observed by running a
thread that is both busy and regularly releases the GIL (for example a loop
doing something then sleeping a few ms after each iteration).  When the
main task is at the REPL, the thread is significantly stalled.  If the main
task is manually made to release the GIL (for example, by calling
utime.sleep_ms(500)) the other thread can be seen immediately working at
the expected speed again.

Additionally, there are various instances in where blocking functions run
MICROPY_EVENT_POLL_HOOK in a loop while they wait for a certain event/
condition.  For example the uselect methods poll objects to determine
whether data is available, but uses 100% of CPU while it does, constantly
calling MICROPY_EVENT_POLL_HOOK in the process.

The MICROPY_EVENT_POLL_HOOK macro is only ever used in waiting loops, where
(if threads are enabled) it makes sense to yield for a single tick so that
these loops do not consume all CPU cycles but instead other threads may
execute.  (In fact, the thing these loops wait for may even indirectly or
directly depend on another task being able to run.)

This change moves the sleep that was inside the REPL input function to
inside the MICROPY_EVENT_POLL_HOOK macro, where the GIL is already being
released, solving both the blocking REPL issue and the 100% CPU use issue
at the same time.

This change allows the same heap allocation rules to be used when using

79ae7098ca esp32/machine_bitstream: Fix signal duplication on output pins.
After changing the bitstream implementation to use the RMT driver in
commit 72d86158121e32bbabaeade08f449d507bf40f9a
("esp32/machine_bitstream.c: Replace with RMT-based driver."), using
multiple `Neopixel` instances shows signal duplication between the
instances (i.e. a `write()` on one instance is written to all instances).

On invocation, the rmt driver configures the GPIO matrix to route the
output signal to the respective GPIO pin.  When called for a different
`NeoPixel` instance using a different pin, the new route is established,
but the old route still exists.  Now, the RMT output signal is sent to both
pins.

Fix this by setting the standard GPIO output function for the current pin
after uninstalling the RMT driver.

86ce442607 ports: Add '.frozen' as the first entry in sys.path.
Frozen modules will be searched preferentially, but gives the user the
ability to override this behavior.

This matches the previous behavior where "" was implicitly the frozen
search path, but the frozen list was checked before the filesystem.

9aa151e3f3 esp32/boards: Remove SPI pin defaults from GENERIC S2/S3 boards.
Default SPI pins are now correctly assigned by machine_hw_spi.c even for S2
and S3.  mpconfigboard.h files define defaults with flipped SPI(1) and
SPI(2) to workaround a bug in machine_hw_spi.c - the bug is fixed.

3305ec44a2 esp32/machine_hw_spi: Fix SPI default pins reordering on ESP32-S2/S3.
The index of machine_hw_spi_obj and machine_hw_spi_default_pins arrays is
assigned to 0 for ARG_id==HSPI_HOST and 1 for another SPI.  On ESP32S2 and
S3 HSPI_HOST=2 so the first set (idx=0) of default pins is used for
SPI(id=2) aka HSPI/SPI3 and the second set (idx=1) for SPI(id=1) aka
FSPI/SPI2.  This makes a misleading mess in MICROPY_HW_SPIxxxx definitions
and it is also in contradiction to the comments around the definitions.

Change the test of ARG_id to fix the order of machine_hw_spi_default_pins.

This change might require adjusting MICROPY_HW_SPIxxxx definitions in
mpconfigboard.h of S2/S3 based boards.

549448e8bb esp32: Enable optimisations and move code to iRAM to boost performance.
This commit enables some significant optimisations for esp32:
- move the VM to iRAM
- move hot parts of the runtime to iRAM (map lookup, load global/name,
  mp_obj_get_type)
- enable MICROPY_OPT_LOAD_ATTR_FAST_PATH
- enable MICROPY_OPT_MAP_LOOKUP_CACHE
- disable assertions
- change from -Os to -O2 for compilation

It's hard to measure performance on esp32 due to external flash and
hardware caching.  But this set of changes improves performance compared to
master by (on a TinyPICO with the GENERIC build, using IDF 4.2.2, running
at 160MHz):

Five tests have more than 3x speed up (200%+).

The performance of the tests bm_fft, bm_pidigits and misc_aes now scale
with CPU frequency (eg changing frequency to 240MHz boosts the performance
of these by 50%), which means they are no longer influenced by timing of
external flash access.  (The viper_call* tests did previously scale with
CPU frequency, and they still do.)

Turning off assertions reduces code size by about 80k, and going from -Os
to -O2 costs about 100k, so the net change in code size (for the GENERIC
board) is about +20k.

If a board wants to enable assertions, or use -Os instead of -O2, that's
still possible by overriding the sdkconfig parameters.

f046b50ca5 esp32/main: Add option for a board to hook code into startup sequence.
To do this the board must define MICROPY_BOARD_STARTUP, set
MICROPY_SOURCE_BOARD then define the new start-up code.

For example, in mpconfigboard.h:

    #define MICROPY_BOARD_STARTUP board_startup
    void board_startup(void);

in mpconfigboard.cmake:

    set(MICROPY_SOURCE_BOARD
        ${MICROPY_BOARD_DIR}/board.c
    )

and in a new board.c file in the board directory:

    #include "py/mpconfig.h"

    void board_startup(void) {
        boardctrl_startup();
        // extra custom startup
    }

This follows stm32's boardctrl facilities.

This commit allows using all the available PWM timers (up to 8) and
channels (up to 16), without affecting the PWM API.

If a new frequency is set, first it checks if another timer is using the
same frequency.  If yes, then it uses this timer, otherwise, it creates a
new one.  If all timers are used, the user should set an already used
frequency, or de-init a channel.
