* Only clear interrupt flags that have fired (so that we do not lose any error flags)
* Enable RX interrupt when a read is requested, disable it when the RX buffer is full
* Rework TX interrupt handling: its "edge" triggered by a FIFO threshold
When data is in the RX fifo the RX timeout interrupt goes high again even after clearing it.
The result is a deadlock because execution is stuck in the interrupt handler. No other code
can run to clear the receive buffer.
Enable and disable RX interrupts based on the buffer fill level.
Use the same approach for the TX code path.
1093: Add random example r=Dirbaio a=miathedev
Thanks Lulf for the help!
This should be added as example so other people can look it up easily.
With love,

1127: clean up doc comment generation r=Dirbaio a=Weshnaw
I noticed that when I created doc comments for my tasks that the doc comments got included on the inner function but not the outer functions, I personally prefer keeping the documentation as clean as possible so this PR aims to hide the inner function and then add doc comments to the outer function.
The actual changes include:
* adding #[doc(hidden)] onto the `task_inner` function
* I flip flopped on this one because I could imagine someone may want this in their docs, but decided to include but I think arguments could be made either way
* copy the attributes from `task_inner` to `task_outer`
* I don't work with proc_macros often so I am not entirely sure if the way I went about it is correct but it seems to work fine
* specifically: using `parse_quote` to create the `task_outer` as a `ItemFn` then duplicating the attributes from `task_inner` to `task_outer`
* I also am not sure if it's a good idea to duplicate all attributes over, but I honestly wasn't sure how to just get the just doc comment attributes

1133: rp: Fill and empty FIFOs in buffered uart interrupt r=Dirbaio a=timokroeger
Fixes an issue where only the first byte was transmitted. Should improve throughput aswell.

1128: Add missing SPI pins r=Dirbaio a=pferreir
The SPI definitions lack the pins which are not accessible on the pico (but are so e.g. on the stamp).

1124: Fix two SPI bugs for stm32 r=Dirbaio a=rmja
This PR fixes two bugs:
* It fixes#1095 by ensuring that pin speed is VeryHigh for all spi versions. I am on stm32f429 which seems to be spi_v1, and it also needs the VeryHigh pin speed. Otherwise bit errors on the "last bit in every byte" can happen.
* It also fixes a lifetime bug for the tx buffer when sending "write_repeated". The issue can be seen when doing spi.write where the clock byte changes during a transmission because the buffer handled to the dma must live throughout the entire transfer.

Hello `@lulf,`
I added some more examples to stm32f0 and tested on hardware.
