Currently when a utf8 character that is bigger than 1 byte is typed in
the repl, it isn't handled how it should be. If you try to move the
cursor in any direction the text gets messed up. This fixes that.
This array was of 32-bit values, but the entries were only ever
in the 0-255 range. Convert to uint8_t.
Testing performed: The result of the sum-of-sin was unchanged
>>> import math; sum(math.sin(2.**i) for i in range(21))
1.42069
This function computes the remainder of a value `x` modulo pi/2, to high
precision.
It does this by dividing the flotaing point values into several ranges
by magnitude, and applies successively slower but more accurate algorithms.
The last two steps, one covering values up to around 2^7 * pi/2
(called "medium size") and a final one covering all possible float values,
require big tables.
By eliminating the "medium size" case, a table and some code are removed
from the binary. This makes some cases take longer, but saves hundreds
of bytes. It does _NOT_ affect the result, only the speed.

This code is imported from musl, to match existing code in libm_dbl.
The file is also added to the build in stm32/Makefile. It's not needed by
the core code but, similar to c5cc64175be32cb1e4f3f1a249667bc9f5a12613,
allows round() to be used by user C modules or board extensions.
Changes in this new library version are:
- Update H7 HAL to v1.6.0.
- Update WB HAL to v1.6.0.
- Add patches to fix F4 ll_uart clock selection for UART9/UART10.

The file `mbedtls_errors/mp_mbedtls_errors.c` can be used instead of
`mbedtls/library/error.c` to give shorter error strings, reducing the build
size of the error strings from about 12-16kB down to about 2-5kB.
So it can be unconditionally included in a port's build even if certain
configurations in that port do not use its features, to simplify the
Makefile.

With only `sp_func_proto_paren = remove` set there are some cases where
uncrustify misses removing a space between the function name and the
opening '('. This sets all of the related options to `force` as well.
This update gives us access to a function we can run with interrupts
disabled to determine if the queue is empty.

No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port. This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.
Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.
The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.
This change is made for two reasons:
1. A 3rd-party library (eg berkeley-db-1.xx, axtls) may use the system
provided errno for certain errors, and yet MicroPython stream objects
that it calls will be using the internal mp_stream_errno. So if the
library returns an error it is not known whether the corresponding errno
code is stored in the system errno or mp_stream_errno. Using the system
errno in all cases (eg in the mp_stream_posix_XXX wrappers) fixes this
ambiguity.
2. For systems that have threading the system-provided errno should always
be used because the errno value is thread-local.
For systems that do not have an errno, the new lib/embed/__errno.c file is
provided.
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.
This is an extremely minimal port to the NXP i.MX RT, in the style of the
SAMD port It's largely based on the TinyUSB mimxrt implementation, using
the NXP SDK. It currently supports the Teensy 4.0 board with a REPL over
the USB-VCP interface.
This commit also adds the NXP SDK submodule (also from TinyUSB) to
lib/nxp_driver.
Note: if you already have the tinyusb submodule initialized recursively you
will need to run the following as the tinyusb sub-submodules have been
rearranged (upstream):
git submodule deinit lib/tinyusb
rm -rf .git/modules/lib/tinyusb
git submodule update --init lib/tinyusb
