This applies to all machine modules which have pins as arguments. Since
machine_pin_get_id() calls pin_find(), these pin arguments may be at the
moment either integer objects or Pin objects. That allows for instance to
write
uart = UART(1, tx=Pin(4), rx=Pin(5))
instead of
uart = UART(1, tx=4, rx=5)
which is consistent with other ports. Since this handling is done at a
single place in the code, extending that scheme to accept strings for named
pins is easy.

The new machine_pin_find() function accepts a Pin object and a integer
object as input and returns a pin object. That can be extended later to
accept a string object, once named pins are supported.

And use it in mp_hal_get_pin_obj() and machine_pin_make_new(). That way,
mp_hal_get_pin_obj() accepts both int and str objects as argument, allowing
use of a pin specifier instead of a pin object in the constructor of
devices which need a pin as parameter.
E.g. instead of
uart = UART(0, tx=Pin(0), rx=Pin(1))
one can write:
uart = UART(0, tx=0, rx=1)

The legacy driver was deprecated in IDF v5, and crashes when the ISR
handler is called. Instead of fixing the legacy code, this commit reworks
the machine.Timer class to use the low-level HAL driver.
Tested on ESP32, ESP32S2, ESP32S3 and ESP32C3. Behaviour is the same as it
was before this commit, except the way the Timer object is printed, it now
gives more useful information (timer id, mode, period in ms).

Prior to this fix, async for assumed the iterator expression was a simple
identifier, and used that identifier as a local to store the intermediate
iterator object. This is incorrect behaviour.
This commit fixes the issue by keeping the iterator object on the stack as
an anonymous local variable.

The existing qspi for stm32 implementation can only send a spi command with
exactly 0 or 2 data bytes. Certain spiflash chips (e.g. AT25SF321B) have
commands that only take a single data byte, and will ignore the command if
more than that is sent. This commit allows sending a command with a single
data byte.

For STM32G4, there is a errata on ADC that may get wrong ADC result.
According to the errata sheet, this can be avoid by performing two
consecutive ADC conversions and keep second result.

For STM32G4 series, the internal sensors are connected to:

For STM32G4, ADC clock frequency should be equal or less than 60MHz.
To satisfy this specification, ADC clock prescaler should be equal or
greater than 4 (For example, NUCLEO_G474RE runs 170MHz).
In addition, to obtain accurate internal channel value,
the ADC clock prescaler is set to 16 because vbat needs at least 12us
(16/170*247.5=23.3us).

For STMG4 MCUs, the peripheral registers for DAC have to be accessed by
words (32bits) because DAC is connected to AHB directly.
(This requirement is also there for other MCU series. However, if DAC is
connected to APB like F4/L1/L4 MCUs, AHB byte or half-word transfer is
changed into a 32-bit APB transfer. This means that PSIZE does not have to
be DMA_PDATAALIGN_WORD on these MCUs, and in fact must be BYTE/HALFWORD to
function correctly.)

This is a fix for commit bccbaa92b1:
- Should only wait for WIFI_EVENT_STA_START when invoked on the STA_IF
interface.
- The WIFI_EVENT_STA_START event is generated every time the STA_IF
interface is set active(True) and it was previously inactive, ie. not
only after calling esp_wifi_start().
- Also wait for WIFI_EVENT_STA_STOP when deactivating the interface.
- Also wait for relevant AP events.

This commit adds the SSLContext class to the ssl module, and retains the
existing ssl.wrap_socket() function to maintain backwards compatibility.
CPython deprecated the ssl.wrap_socket() function since CPython 3.7 and
instead one should use ssl.SSLContext().wrap_socket(). This commit makes
that possible.
For the axtls implementation:
- ssl.SSLContext is added, although it doesn't hold much state because
axtls requires calling ssl_ctx_new() for each new socket
- ssl.SSLContext.wrap_socket() is added
- ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER are added
For the mbedtls implementation:
- ssl.SSLContext is added, and holds most of the mbedtls state
- ssl.verify_mode is added (getter and setter)
- ssl.SSLContext.wrap_socket() is added
- ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER are added
The signatures match CPython:
- SSLContext(protocol)
- SSLContext.wrap_socket(sock, *, server_side=False,
do_handshake_on_connect=True, server_hostname=None)
The existing ssl.wrap_socket() functions retain their existing signature.

This commit updates the esp32 port to work exclusively with ESP-IDF v5.
IDF v5 is needed for some of the newer ESP32 SoCs to work, and it also
cleans up a lot of the inconsistencies between existing SoCs (eg S2, S3,
and C3).
Support for IDF v4 is dropped because it's a lot of effort to maintain both
versions at the same time.
