This fix prevents server.wait_closed() from raising an AttributeError when
trying to access server.task. This can happen if it is called immediately
after start_server().
The random module's getrandbits() method didn't give a proper error message
when calling it with a value that was outside of the range of 1-32, which
can lead to confusion using this function (which under CPython can accept
numbers larger than 32). Now instead of simply giving a ValueError it
gives an error message that states that the number of bits is constrained.
Also, since the random module's functions getrandbits() and randint()
differ from CPython, tests have been added to describe these differences.
For getrandbits the relevant documentation is shown and added to the docs.
The same is given for randint method so that the information is more easily
found.
Finally, since the int object lacks the bit_length() method there is a test
for that method also to include within the docs, showing the difference to
CPython.
If digest is called then the hash object is put in a "final" state and
calling update() or digest() again will raise a ValueError (instead of
silently producing the wrong result).
See issue #4119.

* modframebuf: _mp_framebuf_p_t is not "really" a protocol, but the
QSTR assignment caused problems when building as a dynamic module
* modure: str_index_to_ptr is not in the natmod API, disable URE match
spans when dynamic. mp_obj_len() is a bugfix, we should throw here
if the object is not string-like
* moduzlib: Correct paths to uzlib headers & sources. this relative
path (from moduzlib.c to the referenced file) works in all cases,
the other only worked from ports/PORTNAME.
* dynruntime: Handle 2-arg m_malloc, assert_native_inited, add a
micropythonish mp_arg_check_num_mp, fix mp_raise_msg to use dumb
strings, add mp_raise_arg1
* nativeglue: ad assert_native_inited
* translate: MP_ERROR_TEXT evaluates to its argument for DYNRUNTIME
* mpy-tool: A straggling magic number change
* mpy_ld: Have to renumber manually after dynruntime change
* import_mpy_native_gc.py: Update copy of features0 baked into this test
uctypes.FLOAT32 has a special value representation and
uctypes_struct_scalar_size() should be used instead of GET_SCALAR_SIZE().

The generated regex code is limited in the range of jumps and counts, and
this commit checks all cases which can overflow given the right kind of
input regex, and returns an error in such a case.
This change assumes that the results that overflow an int8_t do not
overflow a platform int.
Closes: #7078

This helps to reduce memory fragmentation, by freeing the heap data as soon
as it is not needed. It also helps the compiler keeps a reference to the
beginning of both arrays, which need to be traceable by the GC (otherwise
some compilers may optimise this reference to something else).

Previously, the MICROPY_PY_BLUETOOTH_ENABLE_CENTRAL_MODE macro
controlled enabling both the central mode and the GATT client
functionality (because usually the two go together).
This commits adds a new MICROPY_PY_BLUETOOTH_ENABLE_GATT_CLIENT
macro that separately enables the GATT client functionality.
This defaults to MICROPY_PY_BLUETOOTH_ENABLE_CENTRAL_MODE.
This also fixes a bug in the NimBLE bindings where a notification
or indication would not be received by a peripheral (acting as client)
as gap_event_cb wasn't handling it. Now both central_gap_event_cb
and peripheral_gap_event_cb share the same common handler for these
events.

Since the datasheet cast some doubt on the strength of the "rosc_hw->randombit",
I use the SHA256 hash function to create a high quality random seed
from random values of uncertain entropy, as well as to generate a sequence
of random values from that seed using SHA256 as a cryptographically-secure
random number generator.
In practice, it produces over 100kB/s of random data which does not
have any gross problems according to _PractRand_.
Zephyr controllers can be queried for a static address (computed from the
device ID). BlueKitchen already supports this, but make them both use the
same macro to enable the feature.
This is a MicroPython-extension that allows for code running in IRQ
(hard or soft) or scheduler context to sequence asyncio code.

On error, the handle is only available on err->att_handle rather than
in attr->handle used in the non-error case.
