This uses MP_REGISTER_ROOT_POINTER() to register all port-specific root
pointers in the esp2866 port.

GPIO interrupts can occur when the flash ROM cache is in use and so the
GPIO interrupt handler must be in iRAM. This commit moves the handler to
iRAM, and also moves mp_sched_schedule to iRAM which is called by
pin_intr_handler.
As part of this fix the Pin class can no longer support hard=True in the
Pin.irq() method, because the VM and runtime are too big to put in iRAM.
Fixes#5714.
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.
Header files that are considered internal to the py core and should not
normally be included directly are:
py/nlr.h - internal nlr configuration and declarations
py/bc0.h - contains bytecode macro definitions
py/runtime0.h - contains basic runtime enums
Instead, the top-level header files to include are one of:
py/obj.h - includes runtime0.h and defines everything to use the
mp_obj_t type
py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
and defines everything to use the general runtime support functions
Additional, specific headers (eg py/objlist.h) can be included if needed.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
