An mp3 decoder (note that this needs `audiocore.get_buffer`, not
enabled on devices):
```py
import sys
import audiomp3
import audiocore
GET_BUFFER_DONE, GET_BUFFER_MORE_DATA, GET_BUFFER_ERROR = range(3)
with audiomp3.MP3Decoder(sys.argv[1]) as decoder, open(sys.argv[2], "wb") as target:
while True:
res, samples = audiocore.get_buffer(decoder)
if res != GET_BUFFER_ERROR:
target.write(samples)
if res != GET_BUFFER_MORE_DATA:
break
```
this doesn't actually add any tests though
bitmapfilter.morph is taken from openmv's imlib.
It is substantially faster than blur/sharpen implemented in ulab,
by up to 10x. It also avoids making many allocations.
This function in standard Python is a building block for custom REPLs:
```python
from codeop import compile_command
print("Repl in (Circuit-)Python")
ns = {}
PS1="<<< "
PS2=",,, "
command = ""
while True:
line = input(PS2 if command else PS1)
if command:
command = command + "\n" + line
else:
command = line
try:
if (code := compile_command(command)):
command = ""
exec(code, ns)
except Exception as e:
command = ""
print(e)
```
This returns the localization of the running CircuitPython, such as
en_US, fr, etc.
Additional changes are needed in build infrastructure since the
string "en_US" should not appear to be translated in weblate, ever;
instead the value comes from the translation metadata.
Closes: #8602
to trade compile speed & flash size
Initially enable the faster mode on rp2040 and espressif, where there's
usually plenty of flash available (these advanced techniques save hundreds
to thousands of bytes, which is important on a lot of old samd21 boards
but is a drop in the lake of a 4MB flash chip)
This provides a way to build a non-DEBUG host binary that still has symbols
and debug information.
Document this for the unix port, and update a comment in the unix port
Makefile.

- Superfluous comments in MP_DEFINE_CONST_OBJ_TYPE stop correct macro
expanding.
- MP_ERROR_TEXT now gives mp_rom_error_text_t, but we want plain const
char *.

In CPython, `_thread.start_new_thread()` returns an ID that is the same ID
that is returned by `_thread.get_ident()`. The current MicroPython
implementation of `_thread.start_new_thread()` always returns `None`.
This modifies the required functions to return a value. The native thread
id is returned since this can be used for interop with other functions, for
example, `pthread_kill()` on *nix. `_thread.get_ident()` is also modified
to return the native thread id so that the values match and avoids the need
for a separate `native_id` attribute.
Fixes issue #12153.

The only reason that const had to be disabled was to make the test output
match CPython when const was involved. Instead, this commit fixes the test
to handle the lines where const is used.
Also:
- remove the special handling for MICROPY_PERSISTENT_CODE_SAVE in
unix/mpconfigport.h, and make this automatic.
- move the check for MICROPY_PERSISTENT_CODE_SAVE to where it's used (like
we do for other similar checks) and add a comment explaining it.
