These calls were all moved into `main.c`, however this call was not
removed from litex. As a result, litex was calling `board_init()` twice.
This is currently not a problem, as `fomu` is able to be initialized
twice without issue, however future boards may have issue with this.
This fixes#2991.

There were two main problems
- word_buffer was being filled as though with unsigned samples,
but during mixing all samples are kept in signed mode
- If the first buffer was stopped, the voices_active flag got set
anyway, even though the output buffer wasn't initialized yet,
so the samples were mixed with indeterminate data
We also cover the case where no buffer was playing, and ensure
the output buffer is filled.
This now works much better. Tested on neotrellis m4 playing back
4 mp3 streams at a time in signed-16, 22050Hz
We can now rely on weblate to regularly update the individual language
files from the template, so "make translate" only needs to update the
template file circuitpython.pot.
This is advantageous because updating the other files in locale/ was
a frequent source of merge conflicts; resolving the conflict incorrectly
was something that could easily occur (and did).
This is almost, but not entirely, a whitespace change.
"..." was missing or mis-placed in several places
The invalid syntax 'def f(self, ):' was used in several places.
From the change:
// xtensa has more registers than an instruction can address. The 16 that
// can be addressed are called the "window". When a function is called or
// returns the window rotates. This allows for more efficient function calls
// because ram doesn't need to be used. It's only used if the window wraps
// around onto itself. At that point values are "spilled" to empty spots in
// the stack that were set aside. When the window rotates back around (on
// function return), the values are restored into the register from ram.
// So, in order to read the values in the stack scan we must make sure all
// of the register values we care about have been spilled to RAM. Luckily,
// there is a HAL call to do it. There is a bit of a race condition here
// because the register value could change after it's been restored but that
// is unlikely to happen with a heap pointer while we do a GC.
Fixes#2907
* Fix flash writes that don't end on a sector boundary. Fixes#2944
* Fix enum incompatibility with IDF.
* Fix printf output so it goes out debug UART.
* Increase stack size to 8k.
* Fix sleep of less than a tick so it doesn't crash.
