910f579403 py/emitnative: Initialise locals as Python object type for native code.
In @micropython.native code the types of variables and expressions are
always Python objects, so they can be initialised as such.  This prevents
problems with compiling optimised code like while-loops where a local may
be referenced before it is assigned to.

ed58d6e4ce extmod/modussl_mbedtls: Fix support for ioctl(MP_STREAM_POLL).
During the initial handshake or subsequent renegotiation, the protocol
might need to read in order to write (or conversely to write in order
to read). It might be blocked from doing so by the state of the
underlying socket (i.e. there is no data to read, or there is no space
to write).

The library indicates this condition by returning one of the errors
`MBEDTLS_ERR_SSL_WANT_READ` or `MBEDTLS_ERR_SSL_WANT_WRITE`. When that
happens, we need to enforce that the next poll operation only considers
the direction that the library indicated.

In addition, mbedtls does its own read buffering that we need to take
into account while polling, and we need to save the last error between
read()/write() and ioctl().

988b6e2dae renesas-ra: Add the UART methods uart.txdone() and uart.flush().
This required to add two functions down the stack to uart.c and ra.sci.c.

- One for telling, whther the transmission is busy.
- One for reporting the size of the TX buffer.

Tested with a EK-RA6M2 board.

5f8f32f917 extmod/modnetwork: Use a type protocol to implement NIC functions.
This was previously implemented by adding additional members to the
mp_obj_type_t defined for each NIC, which is difficult to do cleanly with
the new object type slots mechanism. The way this works is also not
supported on GCC 8.x and below.

Instead replace it with the type protocol, which is a much simpler way of
achieving the same thing.

This affects the WizNet (in non-LWIP mode) and Nina NIC drivers.

564945a2a0 nrf/boards/seeed_xiao_nrf52: Add defn for Seeed XIAO NRF52840 Sense.
It keeps compatibility with the XIAO bootloader by:
- using Soft Device 7.3.0
- reserving 48k memory for the bootloader.

So on double reset a drive pops for uploading an uf2 image or a nrfutil zip
pkg file.  Instructions to create it from a hex file are included.  The
bootloader can as well be activated with the touch 1200 option of nrfutil.

The script download_ble_stack.sh has been adapted to get the version 7.3.0
soft device files.  It may have to be executed once before building.

The file system is set to 256k and the pin definitions are adapted.
Besides that, it has the common functionality and omissions.  The on-board
sensors and additional flash can be supported by Python scripts.

fd1e66edb3 esp32/usb: Cleanup connection detection.
This was introduced by 35fb90bd57, but
it is much simpler and essentially the same to just use
`tud_cdc_n_connected()`.

The only difference is that tud_cdc_n_connected() only checks for DTR,
but this is correct anyway: DTR indicates device presence, RTS indicates
that the host wants to receive data.

9f434dd8de py/gc: Ensure a gap of one byte after the ATB.
Prior to this fix the follow crash occurred.  With a GC layout of:

    GC layout:
      alloc table at 0x3fd80428, length 32001 bytes, 128004 blocks
      finaliser table at 0x3fd88129, length 16001 bytes, 128008 blocks
      pool at 0x3fd8bfc0, length 2048064 bytes, 128004 blocks

Block 128003 is an AT_HEAD and eventually is passed to gc_mark_subtree.
This causes gc_mark_subtree to call ATB_GET_KIND(128004).  When block 1 is
created with a finaliser, the first byte of the finaliser table becomes
0x2, but ATB_GET_KIND(128004) reads these bits as AT_TAIL, and then
gc_mark_subtree references past the end of the heap, which happened to be
past the end of PSRAM on the esp32-s2.

The fix in this commit is to ensure there is a one-byte gap after the ATB
filled permanently with AT_FREE.

Fixes issue #7116.

2283b6d68f py: Pass in address to compiled module instead of returning it.
This change makes it so the compiler and persistent code loader take a
mp_compiled_module_t* as their last argument, instead of returning this
struct.  This eliminates a duplicate context variable for all callers of
these functions (because the context is now stored in the
mp_compiled_module_t by the caller), and also eliminates any confusion
about which context to use after the mp_compile_to_raw_code or
mp_raw_code_load function returns (because there is now only one context,
that stored in mp_compiled_module_t.context).
