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.

d242a9b7f7 rp2/machine_uart: Use read/write mutex to prevent char duplication.
Duplication of characters is caused by re-entrant calls from separate cores
of uart_fill_tx_fifo().  This patch uses a mutex to ensure that a
re-entrant execution of the function returns without affecting the UART
FIFO.

Fixes issues #8344 and #8360.

5873390226 rp2/mphalport: Fix USB CDC RX handling to not block when unprocessed.
Prior to this commit, the USB CDC OUT endpoint got NACK'd if a character
was received but not consumed by the application, e.g. via
sys.stdin.read().  This meant that USB CDC was blocked and no additional
characters could be sent from the host.  In particular a ctrl-C could not
interrupt the application if another character was pending.

To fix the issue, the approach in this commit uses a callback tud_cdc_rx_cb
which is called by the TinyUSB stack on reception of new CDC data.  By
consuming the data immediately, the endpoint does not stall anymore.  The
previous handler tud_cdc_rx_wanted_cb was made obsolete and removed.

In addition some cleanup was done along the way: by adding interrupt_char.c
and removing the existing code mp_hal_set_interrupt_char().  Also, there is
now only one (stdin) ringbuffer.

Fixes issue #7996.

d8a7bf83cc rp2/machine_uart: Fix UART RTS behaviour so RTS is deasserted.
The UART hardware flow control was not working correctly, the receive FIFO
was always fetched and RTS was never deasserted.  This is not a problem
when hardware flow control is not used: normally, if the receive FIFO is
full, the UART receiver won't receive data into the FIFO anymore, but the
current implementation fetches from the FIFO and discards it instead.
The problem is that data is discarded even when RTS is enabled.

This commit fixes the issue by only taking from the FIFO if there is room
in the ring buffer to put the character.

f21c565583 rp2/machine_uart: Handle and clear UART RX timeout IRQ.
The pico-sdk 1.3.0 update in 97a7cc243b
introduced a change that broke RP2 Bluetooth UART, and possibly UART in
general, which stops working right after UART is initialized.  The commit
raspberrypi/pico-sdk@2622e9b enables the UART receive timeout (RTIM) IRQ,
which is asserted when the receive FIFO is not empty, and no more
characters are received for a period of time.

This commit makes sure the RTIM IRQ is handled and cleared in
uart_service_interrupt.

    - blocking
    - non-blocking with callback
    - uasyncio
  - internal ring buffer size can be tuned
- DMA IRQs are managed on an I2S object basis, allowing other
  RP2 entities to use DMA IRQs when I2S is not being used
- MicroPython documentation
- tested on Raspberry Pi Pico development board
- build metric changes for this commit: text(+4552), data(0), bss(+8)

feb7e2e864 rp2/machine_rtc: In RTC.datetime, compute weekday automatically.
Calculating the weekday each time you want to set a date is error prone and
tiresome.  MicroPython can do it on its own - hardware on some ports do not
support storing weekday in hardware and always computes it on the fly,
ignoring the value given to the constructor.

During discussion for #7432 the conclusion was that there seems to be no
obvious reason to let user set the weekday to an incorrect value so it
makes sense to just ignore the provided weekday value and always compute
the correct value.  This patch introduces this change for the rp2 port.

35b1359a3a rp2: Use 0=Monday datetime convention in RTC.
The RTC in rp2 can store any, even wrong, number as a weekday in RTC.  It
was, however, discussed in #7394 that we would like to unify all ports and
use 0 as Monday, not Sunday in the machine.RTC implementation.

This patch makes sure that the default date set in RTC is adheres to this
convention.  It also fixes the example in quickref to use proper weekday to
avoid confusion.

e7f7094ef6 rp2/machine_rtc: Check return value from rtc_set_datetime.
The rtc_set_datetime() from pico-sdk will validate the values in the
datetime_t structure and refuse to set the time if they aren't valid. It
makes sense to raise an exception if this happens instead of failing
silently which might be confusing (as an example, see:
https://github.com/micropython/micropython/pull/6928#issuecomment-860166044
).

37d01d4be3 rp2/machine_rtc: Add initial support for RTC.
Initial support for machine.RTC on rp2 port. It only supports datetime()
method and nothing else. The method gets/returns a tuple of 8 items, just
like esp32 port, for example, but the usec parameter is ignored as the RP2
RTC only works up to seconds precision.

The Pico RTC isn't very useful as the time is lost during reset and there
seems to be no way to easily power up just the RTC clock with a low current
voltage, but still there seems to be use-cases for that, see issues #6831,
and a Thonny issue #1592. It was also requested for inclusion on v1.15
roadmap on #6832.

7ca686684e rp2: Add support for building different board configurations.
This change allows to build firmware for different rp2-based boards,
following how it is done in other ports like stm32 and esp32.  So far only
the original Pico and Adafruit Feather RP2040 are added.  Board names
should match (sans case) those in pico-sdk/src/boards/include/boards/.

Usage: Pico firmware can be build either using make as previously (it is
the default board) or by `make BOARD=PICO`.  Feather is built by `make
BOARD=ADAFRUIT_FEATHER_RP2040`.  Only the board name and flash drive size
is set, pin definition is taken from the appropriate pico-sdk board
definition.  Firmware is saved in the directory build-BOARD_NAME.

Instantiation and init now support the rxbuf and txbuf keywords for setting
the buffer size.  The default size is 256 bytes.  The minimum and maximum
sizes are 32 and 32766 respectively.

uart.write() still includes checks for timeout, even if it is very unlikely
to happen due to a) lack of flow control support and b) the minimal timeout
values being longer than the time it needs to send a byte.

22554cf8e2 rp2/rp2_pio: Add StateMachine restart,rx_fifo,tx_fifo helper functions.
StateMachine.restart: Restarts the state machine
StateMachine.rx_fifo: Return the number of RX FIFO items, 0 if empty
StateMachine.tx_fifo: Return the number of TX FIFO items, 0 if empty

restart() seems to be the most useful one, as it resets the state machine
to the initial state without the need to re-initialise/re-create.  It also
makes PIO code easier, because then stalling as an error state can be
unlocked.

rx_fifo() is also useful, for MP code to check for data and timeout if no
data arrived.  Complex logic is easier handled in Python code than in PIO
code.

tx_fifo() can be useful to check states where data is not processed, and is
mostly for symmetry.

6f06dcaee5 rp2/moduos: Implement uos.urandom().
The implementation samples rosc.randombits at a frequency lower than the
oscillator frequency.  This gives better random values.  In addition, for
an 8-bit value 8 samples are taken and fed through a 8-bit CRC,
distributing the sampling over the byte.  The resulting sampling rate is
about 120k/sec.

The RNG does not include testing of error conditions, like the ROSC being
in sync with the sampling or completely failing.  Making the interim value
static causes it to perform a little bit better in short sync or drop-out
situations.

The output of uos.urandom() performs well with the NIST800-22 test suite.
In my trial it passed all tests of the sts 2.1.2 test suite.  I also ran a
test of the random data with the Common Criteria test suite AIS 31, and it
passed all tests too.

4f53f462ca rp2: Import uarray instead of array in rp2 module.
Some forum users noticed that `sm.exec()` took longer the more was present
on the flash filesystem connected to the RP2040.  They traced this back to
the `array` import inside `asm_pio()`, which is causing MicroPython to scan
the filesystem.

uarray is a built-in module, so importing it shouldn't require scanning the
filesystem.

We avoid moving the import to the top-level in order to keep the namespace
clean; we don't want to accidentally expose `rp2.array`.

0cf12dd59c rp2: Add support for USER_C_MODULES to CMake build system.
The parts that are generic are added to py/ so they can be used by other
ports that use CMake.

py/usermod.cmake:

* Creates a usermod target to hang user C/CXX modules from.
* Gathers sources from user C/CXX modules and libs for QSTR scan.

ports/rp2/CMakeLists.txt:

* Includes py/usermod.cmake.
* Links the resulting usermod library to the MicroPython target.

py/mkrules.cmake:

Add cxxflags to qstr.i.last custom command for CXX modules:

* MICROPY_CPP_FLAGS so CXX modules will find includes.
* -DNO_QSTR to fix fatal error missing "genhdr/qstrdefs.generated.h".

Usage:

The rp2 port can be linked against user C modules by running:

make USER_C_MODULES=/path/to/module/micropython.cmake

CMake will print a list of included modules.
