This optimises the case where a Python function is, for example, stored to
a JavaScript attribute and then later retrieved from Python. The Python
function no longer needs to be a proxy with double proxying needed for the
call from Python -> JavaScript -> Python.

Ports that use axtls cannot run the `test_tls_sites.py` test because the
sites it connects to use advanced ciphers. So skip this test on such
ports, and add a new, simpler test that doesn't require certificate
verification and works with axtls.

This is required because the .mpy native ABI was changed by the
introduction of `mp_proto_fun_t`, see commits:
- 416465d81e

And three `mp_binary` functions were added to `mp_fun_table` in
commit d2276f0d41.

Add `pop()`, `appendleft()`, and `extend()` methods, support iteration
and indexing, and initializing from an existing sequence.
Iteration and indexing (subscription) have independent configuration flags
to enable them. They are enabled by default at the same level that
collections.deque is enabled (the extra features level).
Also add tests for checking new behavior.

This new DMA API corrects possible cache coherency issues on chips with
D-Cache, when working with buffers at arbitrary memory locations (i.e.
supplied by Python code).
The API is used by SPI to fix an issue with corrupt data when reading from
SPI using DMA in certain cases. A regression test is included (it depends
on external hardware connection).
Explanation:
1) It's necessary to invalidate D-Cache after a DMA RX operation completes
in case the CPU reads (or speculatively reads) from the DMA RX region
during the operation. This seems to have been the root cause of issue
#13471 (only when src==dest for this case).
2) More generally, it is also necessary to temporarily mark the first and
last cache lines of a DMA RX operation as "uncached", in case the DMA
buffer shares this cache line with unrelated data. The CPU could
otherwise write the other data at any time during the DMA operation (for
example from an interrupt handler), creating a dirty cache line that's
inconsistent with the DMA result.
Fixes issue #13471.

When the websocket closes currently, it does not send a proper
"close"-frame, but rather encodes the 0x8800-sequence inside a binary
packet, which is wrong. The close packet is a different kind of websocket
frame, according to https://www.rfc-editor.org/rfc/rfc6455.
This change resolves an error in Firefox when the websocket closes.

Similar to the previous commit but for MP_BLUETOOTH_IRQ_GATTC_READ_DONE:
the pending_value_handle needs to be reset before calling
mp_bluetooth_gattc_on_read_write_status(), which will call the Python IRQ
handler, which may in turn call back into BTstack to perform an action like
a write. In that case the pending_value_handle will need to be available
for the write/read/etc to proceed.

The current `ssl` module has quite a few differences to the CPython
implementation. This change moves the MicroPython variant to a new `tls`
module and provides a wrapper module for `ssl` (in micropython-lib).
Users who only rely on implemented comparible behavior can continue to use
`ssl`, while users that rely on non-compatible behavior should switch to
`tls`. Then we can make the facade in `ssl` more strictly adhere to
CPython.

If a return is executed within the try block of a try-finally then the
return value is stored on the top of the Python stack during the execution
of the finally block. In this case the Python stack is one larger than it
normally would be in the finally block.
Prior to this commit, the compiler was not taking this case into account
and could have a Python stack overflow if the Python stack used by the
finally block was more than that used elsewhere in the function. In such
a scenario the last argument of the function would be clobbered by the
top-most temporary value used in the deepest Python expression/statement.
This commit fixes that case by making sure enough Python stack is allocated
to the function.
Fixes issue #13562.

Changes include:
- Some mbedtls source files renamed or deprecated.
- Our `mbedtls_config.h` files are renamed to `mbedtls_config_port.h`, so
they don't clash with mbedtls's new default configuration file named
`mbedtls_config.h`.
- MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE is deprecated.
- MBEDTLS_HAVE_TIME now requires an `mbedtls_ms_time` function to be
defined but it's only used for TLSv1.3 (currently not enabled in
MicroPython so there is a lazy implementation, i.e. seconds * 1000).
- `tests/multi_net/ssl_data.py` is removed (due to deprecation of
MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_KEY_EXCHANGE), there are the existing
`ssl_cert_rsa.py` and `sslcontext_server_client.py` tests which do very
similar, simple SSL data transfer.
- Tests now use an EC key by default (they are smaller and faster), and the
RSA key has been regenerated due to the old PKCS encoding used by openssl
rsa command, see
https://stackoverflow.com/questions/40822328/openssl-rsa-key-pem-and-der-conversion-does-not-match
(and `tests/README.md` has been updated accordingly).

These were added back in commit c4935f3049
because the tests required CPython 3.8, which was quite new at the time.
But CPython 3.8 was released over 4 years ago (October 2019) and the CI
test runners, and developers, have this (or a more recent) CPython version.
Removing the .exp files also helps keep MicroPython semantics the same as
CPython.

Compare the full absolute path instead of relying on the path form
passed by the user.
For instance, this will make
python3 run-tests.py -d basics
python3 run-tests.py -d ./basics
python3 run-tests.py -d ../tests/basics
python3 run-tests.py -d /full/path/to/basics
all behave the same by correctly treating the bytes_compare3 and
builtin_help tests as special, whereas previously only the first
invocation would do that and hence result in these tests to fail
when called with a different path form.

This matches the behaviour of run-tests.py, which sets cwd to the directory
containing the test script, which helps to isolate the filesystem.
It means that the SSL tests no longer need to know the name of their
containing directory to find the certificate files, and helps to run these
tests on bare-metal.

The existing thread_sleep1.py test only tests execution, not accuracy, of
time.sleep. Also the existing test only tests sleep(0) on targets like rp2
that can only create a single thread.

and one other thread when they run at the same time.

The aim of this commit is to make it so that the existing thread tests can
be used to test the _thread module on the rp2 port. The rp2 port only
allows up to one thread to be created at a time, and does not have the GIL
enabled.
The following changes have been made:
- run-tests.py skips mutation tests on rp2, because there's no GIL.
- run-tests.py skips other tests on rp2 that require more than one thread.
- The tests stop trying to start a new thread after there is an OSError,
which indicates that the system cannot create more threads.
- Some of these tests also now run the test function on the main thread,
not just the spawned threads.
- In some tests the output printing is adjusted so it's the same regardless
of how many threads were spawned.
- Some time.sleep(1) are replaced with time.sleep(0) to make the tests run
a little faster (finish sooner when the work is done).
For the most part the tests are unchanged for existing platforms like esp32
and unix.
