reset_port calls reset_all_pins, which disables the built-in pull
down. In theory, this could allow some CYW43 interfacing pin to float
to an inappropriate value. There's no proof of this! but the move can't
really hurt, either
* use a virtual fat filesystem during the test
* this makes the file I/O part more closely patch runtime which is nice
* side-steps the need to add a special function for testing
* but test still can't be run on a device, because the vfs calls
are incompatible, and you intentionally can't remount "/" anyway
* and side-steps problems with storing 'bad' toml files
I wanted to use the idiom
```c
#if GUARD
if (condition) {
alternate code
} else
#else
{
common default code
}
```
idiom, in which the common default code is conditioned both on a
compile-time check and a run-time check. However, I got it wrong
and uncrustify chipped in, adding extra brackets around a following
piece of code and re-indenting it.
* Set nonblock on all accepted sockets. Not just ones for user code.
* Close an open websocket if another is accepted.
* Set debug level to INFO rather than DEBUG because DEBUG crashes
on ESP32-S3 USB OTG.
* read() is now readinto() and takes the buffer to write into.
* readinto() returns the number of valid samples.
* readinto() can be interrupted by ctrl-c.
* readinto() API doesn't support signed numbers because it never did.
* sample_rate is now required in the constructor because supported
values will vary per-port.
* 16 bit values are full range. 12 bit samples from RP2040 are stretched
in the same way they are for AnalogIn.
Fixes#7226
A crash would occur if an SSL socket was not shut down before
`gc_deinit()`.
I do not fully understand the root cause, but some object deinitialization
/ deallocation prior to `gc_deinit` leaves the SSL object in an
inconsistent state.
Rather than resolve the root cause, instead ensure that the closing of
the user socket also closes the SSL socket.
Closes: #6502
