6bc50c4fa9 stm32/systick: Always POLL_HOOK when delaying for milliseconds. 
Call MICROPY_EVENT_POLL_HOOK even on very short delays so that busy loops
that call sleep_ms still yield to events and other threads.

See related issue #5344.

db6d60b079 extmod/utime: Always invoke mp_hal_delay_ms when >= to 0ms. 
This makes sleep_ms(0) useful as a "yield" so event processing and thread
switching can take place.

Fixes issue #5345.

In 2ae3c890bd, -Wimplicit-fallthrough=0 was
added to get the build to pass.  This option is equivalent to
-Wno-implicit-fallthrough, and the latter is compatible with clang (while
the former is not).

12e3fcc785 extmod/nimble: Fix leak in l2cap_send if send-while-stalled. 
A correctly-behaved application shouldn't do this, but in the
case where the channel is stalled, there's still enough room
in the mbuf pool, then we'll fail the send (BLE_HS_EBUSY) so
the mbuf needs to be freed.

This adds #if MICROPY_PY_USELECT_SELECT around the uselect.select()
function. According to the docs, this function is only for CPython
compatibility and should not normally be used. So we can disable it
and save a few bytes of flash space where possible.

8be29b9b1b esp32/machine_hw_spi: Use a 2 item SPI queue for long transfers. 
Using a 2-item transaction queue instead of 1 allows long transfers to 
be executed with the minimum inter-transaction delay. Limit maximum 
transaction length to ensure an integer multiple of the SPI `bits` 
setting are transferred. Fixes #7511.

bb00125aaa py: Support single argument to optimised MP_OBJ_STOP_ITERATION. 
The MP_OBJ_STOP_ITERATION optimisation is a shortcut for creating a
StopIteration() exception object, and means that heap memory does not need
to be allocated for the exception (in cases where it can be used).  This
commit allows this optimised object to take an optional argument (before,
it could only have no argument).

The commit also adds some new tests to cover corner cases with
StopIteration and generators that previously did not work.

4d546713ec shared: Introduce new top-level dir and move 1st party lib code there. 
This commit moves all first-party code developed for this project from lib/
to shared/, so that lib/ now only contains third-party code.

The following directories are moved as-is from lib to shared:

    lib/libc            -> shared/libc
    lib/memzip          -> shared/memzip
    lib/netutils        -> shared/netutils
    lib/timeutils       -> shared/timeutils
    lib/upytesthelper   -> shared/upytesthelper

All files in lib/embed/ have been moved to shared/libc/.

lib/mp-readline has been moved to shared/readline.

lib/utils has been moved to shared/runtime, with the exception of
lib/utils/printf.c which has been moved to shared/libc/printf.c.
