Add documentation for `machine.Counter` and `machine.Encoder` as currently

- DTLS spec recommends HelloVerify and Anti Replay protection be enabled,
and these are enabled in the default mbedTLS config. Implement them here.
- To help compensate for the possible increase in code size, add a
MICROPY_PY_SSL_DTLS build config macro that's enabled for EXTRA and
above by default.
This allows bare metal mbedTLS ports to use DTLS with HelloVerify support.

Currently the `FrameBuffer.blit(buf, x, y)` method requires the `buf`
argument to be another `FrameBuffer`, which is quite restrictive because it
doesn't allow blit'ing read-only memory/data.
This commit extends `blit()` to allow the `buf` argument to be a tuple or
list of the form:
(buffer, width, height, format[, stride])
where `buffer` can be anything with the buffer protocol and may be
read-only, eg `bytes`.
Also, the palette argument to `blit()` may be of the same form.
The form of this tuple/list was chosen to be the same as the signature of
the `FrameBuffer` constructor (that saves quite a bit of code size doing it
that way).

This adds a new function, `esp32.idf_task_info()`, that can be used to

tasks are using up a lot of CPU time.
It's best used in conjunction with the `utop` module from micropython-lib.

Commit 1b6e0f64796dfd6f86a8679ea6d24e1fca1e63a8 for Zephyr v4.0.0
changed the function "thread_analyzer_print" to require a cpu argument
and allow thread analysis on each cpu separately. The argument is
ignored when THREAD_ANALYZER_AUTO_SEPARATE_CORES=n which is the
default on single core machines.
Promote this change to the MicroPython zephyr module.

This commit introduces the ability to obtain a list of stations
connected to the device when in soft-AP mode.
A new parameter ("stations") to pass to WLAN.status is supported,
returning a tuple of (bssid, ipv4) entries, one per connected station.
An empty tuple is returned if no stations are connected, and an
exception is raised if an error occurred whilst building the python
objects to return to the interpreter.
Documentation is also updated to cover the new parameter.
This fixes #5395.

For a given MicroPython firmware/executable it can be sometimes important
to know how it was built, which variant/board configuration it came from.
This commit adds a new field `sys.implementation._build` that can help
identify the configuration that MicroPython was built with.
For now it's either:
* <VARIANT> for unix, webassembly and windows ports
* <BOARD>-<VARIANT> for microcontroller ports (the variant is optional)
In the future additional elements may be added to this string, separated by
a hyphen.
Resolves issue #16498.

This commit enables support for DTLS, i.e. TLS over datagram transport
protocols like UDP. While support for DTLS is absent in CPython, it is
worth supporting it in MicroPython because it is the basis of the
ubiquitous CoAP protocol, used in many IoT projects.
To select DTLS, a new set of "protocols" are added to SSLContext:
- ssl.PROTOCOL_DTLS_CLIENT
- ssl.PROTOCOL_DTLS_SERVER
If one of these is set, the library assumes that the underlying socket is a
datagram-like socket (i.e. UDP or similar).
Our own timer callbacks are implemented because the out of the box
implementation relies on `gettimeofday()`.
This new DTLS feature is enabled on all ports that use mbedTLS.
This commit is an update to a previous PR #10062.
Addresses issue #5270 which requested DTLS support.

This commit adds a clarification for the ESPNow module's documentation
regarding its "config" method.
The original documentation for that method could be interpreted as having
all its configuration keys being able to be queried, but the "rate"
configuration key is actually write-only due to ESP-IDF's lack of a way to
retrieve that bit of information from the radio's configuration. The
documentation changes highlight the fact that said configuration key is
actually write-only.

Not every baudrate or sample point combination has an exact match,
but getting within 1% on sample point and .1% on baud rate should
always be good enough.
Because the search goes from shorter bit periods (lowest brp) and
increases, the first match which meets this criteria should still mostly be
the best available.

This commit makes the argument ordering of `machine.RTC.init()` the same

The current documentation for the `machine.RTC` class contains information
about the `RTC.cancel` method for cancelling pending alarms.
However only two ports (cc3200 and mimxrt) implement this functionality
but under a different name: `RTC.alarm_cancel`. The mimxrt port also
implements `RTC.cancel` but it is aliased to `RTC.alarm_cancel` anyway.
To maintain naming consistency, this commit updates the documentation to
officially define `RTC.alarm_cancel` as the method to call to cancel
pending alarms and deprecates mimxrt's `RTC.cancel` implementation.
`RTC.cancel` in the mimxrt port is thus scheduled for removal in
MicroPython v2.

Prior to this commit, when flushing a UART on the rp2 port, it returns just
before the last character is sent out the wire.
Fix this by waiting until the BUSY flag is cleared.
This also fixes the behaviour of `UART.txdone()` to return `True` only when
the last byte has gone out.
Updated docs and tests to match. The test now checks that UART TX time is
very close to the expected time (prior, it was just testing that the TX
time was less than the expected time).

This commit adds a new `RingIO` type which exposes the internal ring-buffer
code for general use in Python programs. It has the stream interface
making it similar to `StringIO` and `BytesIO`, except `RingIO` has a fixed
buffer size and is automatically safe when reads and writes are in
different threads or an IRQ.
This new type is enabled at the "extra features" ROM level.
