When looping, now disable the TX interrupt after calling rmt_write_items()
function to handle change in IDF behaviour (since v4.1). Also check length
of pulses to ensure it fits hardware limit.
Fixes issue #7403.
Dynamically generate/loaded native code (eg from @micropython.native or
native .mpy files) needs to be able allocate from IRAM, and the memory
protection feature must be disabled for that to work. Disabling it is
needed to get native code working on ESP32-S2 and -C3.

This adds a wlan.config(reconnects=N) option to set the number of reconnect
attempts that will be made if the WLAN connection goes down. The default
is N=-1 (infinite retries, current behavior). Setting
wlan.config(reconnects=0) will disable the reconnect attempts.
A nice side effect of reconnects=0 is that wlan.status() will report the
disconnect reason now. See related issue #5326.
Ethernet-PHYs from ESP-IDF (LAN8720, IP101, RTL8201, DP83848) are now
supported in IDF v4.1 and above. PHY_KSZ8041 is only for ESP-IDF 4.3 and
above. ESP32S2 is not supported.

Changes introduced are:
- the application offset is now loaded from the partition table instead of
being hard-coded to 0x10000
- maximum size of all sections is computed using the partition table
- an error is generated if any section overflows its allocated space
- remaining bytes are printed for each section

Adds support for NeoPixels on GPIO32 and GPIO33 on ESP32. Otherwise,
NeoPixels wired to GPIO32/33 wll silently fail without any hints to the
user.
With thanks to @robert-hh.
Fixes issue #7221.
ATOM is a very small ESP32 development board produced by M5Stack, with a
size of 24mm * 24mm, with peripherals such as WS2812, IR, button, MPU6886
(Only Matrix), and 8 GPIO extensions. It also has a plastic shell.
Improvements made:
- PSRAM support for S2
- partition definition for 16MiB flash
- correct ADC and DAC pins
- correct GPIO and IRQ pins
- S3 components in CMakeLists

This commit re-enables the command-line make option "FROZEN_MANIFEST". The
boards/*/mpconfigboard.cmake will now use the command-line FROZEN_MANIFEST
value if supplied.
Usage: make FROZEN_MANIFEST=~/foo/my-manifest.py
Because "find_package(Python3 ...)" requires at least this version of
CMake. And other features like GREATER_EQUAL and COMMAND_EXPAND_LISTS need
at least CMake 3.7 and 3.8 respectively.

Commit 8a917ad252 added the gpio_reset_pin()
call to make sure that pins that were used as ADC inputs could subsequently
be used as digital IO. But calling gpio_reset_pin() will enable the
pull-up on the pin and so pull it high for a brief period. Instead use
rtc_gpio_deinit() which will just reconfigure the pin as a digital IO and
do nothing else.
Fixes issue #7079 (see also #5771).

For an unconnected TCP socket, poll should return WR|HUP and read should
raise ENOTCONN. This is implemented by this commit and now the following
tests pass on esp32: extmod/usocket_tcp_basic.py,
net_hosted/connect_poll.py.

It was noticed that the esp32 port didn't build ulab correctly. The
problem was a multiple defintion of the 'mp_hal_stdout_tx_str' and
'mp_hal_stdout_tx_strn_cooked' functions.
They were defined in stdout_helpers.c but also in the
ports/esp32/mphalport.c.
Fixed by removing stdout_helpers.c from the build.

Support for User C and C++ modules was lost due to upgrading the esp32 to

Restore the support for the esp32 port by integrating with the approach
recently added for the rp2 port.

This commit fixes two issues on the esp32:
- it enables machine.soft_reset() to be called in main.py;
- it enables machine.reset_cause() to correctly identify a soft reset.
The former is useful in that it enables soft resets in applications that
are started at boot time. The support is patterned after the stm32 port.
This commit implements basic NVS support for the esp32. It follows the
pattern of the esp32.Partition class and exposes an NVS object per NVS
namespace. The initial support provided is only for signed 32-bit integers
and binary blobs. It's easy (albeit a bit tedious) to add support for
more types.

This enables -Os for compilation, but still keeps full assertion messages.
With IDF v4.2, -Os changes the GENERIC firmware size from 1512176 down to
1384640, and the GENERIC_SPIRAM firmware is now 1452320 which fits in the
allocated partition.

The underlying OS (the ESP-IDF) uses it's own internal errno codes and so
it's simpler and cleaner to use those rather than trying to convert
everything to the values defined in py/mperrno.h.
