81985d20c9 shared/runtime/mpirq: Check separate hard IRQ stack correctly.
On the zephyr port, hard IRQ handlers run with a separate stack on a
different thread, so each call to mp_irq_dispatch() and mp_irq_handler()
has to be wrapped with adjustments to the stack-limit checker.

Move these adjustments into the shared mp_irq_dispatch(), introducing
MICROPY_STACK_SIZE_HARD_IRQ which a port can define to non-zero if it
uses a separate stack for hard IRQ handlers. We only need wrap the hard
dispatch case. This should reduce binary size on zephyr without affecting
other ports.

706cc8d833 shared/runtime/mpirq: Factor out mp_irq_dispatch() and use it.
Separate out a routine to call an arbitrary function with arbitrary
argument either directly as a hard-IRQ handler or scheduled as a soft-IRQ
handler, adjusting mp_irq_handler() to wrap this. This can then be used
to implement other hard/soft callbacks, such as for machine.Timer.

decf8e6a8b all: Remove the "STATIC" macro and just use "static" instead.
The STATIC macro was introduced a very long time ago in commit
d5df6cd44a.  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.

94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

4d546713ec shared: Introduce new top-level dir and move 1st party lib code there.
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.
