This commit renames the NORETURN macro, indicating to the compiler
that a function does not return, into MP_NORETURN to maintain the same
naming convention of other similar macros.
To maintain compaitiblity with existing code NORETURN is aliased to
MP_NORETURN, but it is also deprecated for MicroPython v2.
This changeset was created using a similar process to
decf8e6a8bb940d5829ca3296790631fcece7b21 ("all: Remove the "STATIC"
macro and just use "static" instead."), with no documentation or python
scripts to change to reflect the new macro name.

The STATIC macro was introduced a very long time ago in commit
d5df6cd44a433d6253a61cb0f987835fbc06b2de. The original reason for this was
to have the option to define it to nothing so that all static functions
become global functions and therefore visible to certain debug tools, so
one could do function size comparison and other things.
This STATIC feature is rarely (if ever) used. And with the use of LTO and
heavy inline optimisation, analysing the size of individual functions when
they are not static is not a good representation of the size of code when
fully optimised.
So the macro does not have much use and it's simpler to just remove it.
Then you know exactly what it's doing. For example, newcomers don't have
to learn what the STATIC macro is and why it exists. Reading the code is
also less "loud" with a lowercase static.
One other minor point in favour of removing it, is that it stops bugs with
`STATIC inline`, which should always be `static inline`.
Methodology for this commit was:
1) git ls-files | egrep '\.[ch]$' | \
xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/"
2) Do some manual cleanup in the diff by searching for the word STATIC in
comments and changing those back.
3) "git-grep STATIC docs/", manually fixed those cases.
4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

C99 says that strncmp has UB for either string being NULL, so the
current behavior is technically correct, but it's an easy fix to handle
this case correctly.
7.1.4: "unless explicitly stated otherwise in the detailed
description... if an argument to a function has ...null pointer.. the
behavior is undeļ¬ned".
7.21.1: "Unless explicitly stated otherwise in the description of a
particular function in this subclause, pointer arguments on such a call
shall still have valid values, as described in 7.1.4".
Also make the same change for the minimal version in bare-arm/lib.c.

These functions should output to the same location as printf in this file.

The C-level printf is usually used for internal debugging prints, and a
port/board may want to redirect this somewhere other than stdout.

Some toolchains will have string.h defining various macros which can lead
to compile errors for string function implementations. Not including
string.h fixes this.
An implementation of __memcpy_chk is provided for toolchains that enable
_FORTIFY_SOURCE.
Fixes issue #6046.

This commit moves all first-party code developed for this project from lib/
to shared/, so that lib/ now only contains third-party code.
The following directories are moved as-is from lib to shared:
lib/libc -> shared/libc
lib/memzip -> shared/memzip
lib/netutils -> shared/netutils
lib/timeutils -> shared/timeutils
lib/upytesthelper -> shared/upytesthelper
All files in lib/embed/ have been moved to shared/libc/.
lib/mp-readline has been moved to shared/readline.
lib/utils has been moved to shared/runtime, with the exception of
lib/utils/printf.c which has been moved to shared/libc/printf.c.
