This verifies the behavior:
- Exact matches of built-ins bypass filesystem.
- u-prefix modules can be overridden from the filesystem.
- Builtin import can be forced using either u-prefix or sys.path=[].

This demonstrates how to add a sub-package in a user c module, as well
as how to define the necessary qstrs and enable the feature in the build.
This is used by the unix coverage build to test this feature.

This generalises and simplifies the code and follows CPython behaviour.

This is possible now that MP_UNARY_OP_INT_MAYBE exists.
As a consequence mp_obj_get_int now also supports user types, which was
previously possible with MP_UNARY_OP_INT but no tests existed for it.

To be consistent with MP_UNARY_OP_INT_FLOAT and MP_UNARY_OP_INT_COMPLEX,
and allow int() to first check if a type supports __int__ before trying
other things (as per CPython).

MicroPython does not support these special methods, and they may get in the
way of other tests (eg indexing with __int__).

Apply envelope & panning after biquad filtering.
This may fix the weird popping problem. It also reduces the number
of operations that are done "in stereo", so it could help performance.
It also fixes a previously unnoticed problem where a ring-modulated
waveform had 2x the amplitude of an un-modulated waveform.
The test differences look large but it's because some values got changed
in the LSB after the mathematical divisions were moved around.
The code that handles inplace-operator to normal-binary-operator fallback
is moved in this commit from py/objtype.c to py/runtime.c, making it apply
to all types, not just user classes.

So that user types can implement reverse operators and have them work with
str on the left-hand-side, eg `"a" + UserType()`.

This adds a unary_op implementation for the dict_view type that makes
the implementation of `hash()` for these types compatible with CPython.

As per https://bugs.python.org/issue408326, the slice object should not be
hashable. Since MicroPython has an implicit fallback when the unary_op
slot is empty, we need to fill this slot.

Previously when using --via-mpy, the file was compiled to tests/<tmp>.mpy
and then run using `micropython -m <tmp>` in the current cwd
(usually tests/). This meant that an import in the test would be resolved
relative to tests/.
This is different to regular (non-via-mpy) tests, where we run (for
example) `micropython basics/test.py` which means that an import would be
resolved relative to basics/.
Now --via-mpy matches the .py behavior. This is important because:
a) It makes it so import tests do the right thing.
b) There are directory names in tests/ that match built-in module names.
Furthermore, it always ensures the cwd (for both micropython and cpython)
is the test directory (e.g. basics/) rather than being left unset. This
also makes it clearer inside the test that e.g. file access is relative to
the Python file.
Updated tests with file paths to match.

this has the side effect of making some notes more accurate, the new
frequency= value in the test is closer to the true midi frequency of
830.609...Hz.
This class allows much more expressive sound synthesis:
* tremolo & vibrato
* arbitrary frequency
* different evelope & waveform per note
* all properties dynamically settable from Python code
When a tuple is the condition of an if statement, it's only possible to
optimise that tuple away when it is a constant tuple (ie all its elements
are constants), because if it's not constant then the elements must be
evaluated in case they have side effects (even though the resulting tuple
will always be "true").
The code before this change handled the empty tuple OK (because it doesn't
need to be evaluated), but it discarded non-empty tuples without evaluating
them, which is incorrect behaviour (as show by the updated test).
This optimisation is anyway rarely applied because it's not common Python
coding practice to write things like `if (): ...` and `if (1, 2): ...`, so
removing this optimisation completely won't affect much code, if any.
Furthermore, when MICROPY_COMP_CONST_TUPLE is enabled, constant tuples are
already optimised by the parser, so expression with constant tuples like
`if (): ...` and `if (1, 2): ...` will continue to be optimised properly
(and so when this option is enabled the code that's deleted in this commit
is actually unreachable when the if condition is a constant tuple).

ESP-NOW is a proprietary wireless communication protocol which supports
connectionless communication between ESP32 and ESP8266 devices, using
vendor specific WiFi frames. This commit adds support for this protocol
through a new `espnow` module.
This commit builds on original work done by @nickzoic, @shawwwn and with
contributions from @zoland. Features include:
- Use of (extended) ring buffers in py/ringbuf.[ch] for robust IO.
- Signal strength (RSSI) monitoring.
- Core support in `_espnow` C module, extended by `espnow.py` module.
- Asyncio support via `aioespnow.py` module (separate to this commit).
- Docs provided at `docs/library/espnow.rst`.
Methods available in espnow.ESPNow class are:
- active(True/False)
- config(): set rx buffer size, read timeout and tx rate
- recv()/irecv()/recvinto() to read incoming messages from peers
- send() to send messages to peer devices
- any() to test if a message is ready to read
- irq() to set callback for received messages
- stats() returns transfer stats:
(tx_pkts, tx_pkt_responses, tx_failures, rx_pkts, lost_rx_pkts)
- add_peer(mac, ...) registers a peer before sending messages
- get_peer(mac) returns peer info: (mac, lmk, channel, ifidx, encrypt)
- mod_peer(mac, ...) changes peer info parameters
- get_peers() returns all peer info tuples
- peers_table supports RSSI signal monitoring for received messages:
{peer1: [rssi, time_ms], peer2: [rssi, time_ms], ...}
ESP8266 is a pared down version of the ESP32 ESPNow support due to code
size restrictions and differences in the low-level API. See docs for
details.
Also included is a test suite in tests/multi_espnow. This tests basic
espnow data transfer, multiple transfers, various message sizes, encrypted
messages (pmk and lmk), and asyncio support.
Initial work is from https://github.com/micropython/micropython/pull/4115.
Initial import of code is from:
https://github.com/nickzoic/micropython/tree/espnow-4115.
