9fea0e98b1 esp8266/machine_pin: Accept an integer argument to mp_obj_get_pin_obj.
Allowing the machine.pwm() and esp.apa102() module to accept Pin(x) integer
parameters.  Not so much of a gain, just consistent with other ports.

d9bca305e5 esp8266/machine_pin: Disable open drain when pin becomes input/output.
Otherwise the pin stays in open drain mode.

96a2cc5e13 esp8266/machine_pwm: Enable real open drain output on pin driven by PWM.
The PWM module now detects if the pin is open drain and if so switches it
to hardware open drain before starting the PWM.

The code that was explicitly turning off the open drain output during PWM
is also removed.

Together these changes allow driving external transistor high-current
switches with PWM.

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.

e2d4db96da esp8266: Use MP_REGISTER_ROOT_POINTER().
This uses MP_REGISTER_ROOT_POINTER() to register all port-specific root
pointers in the esp2866 port.

e12de1fd9d esp8266: Clean up Pin intr handler by moving all code to machine_pin.c.
The macro MP_FASTCODE is used to explicitly place required functions in
iRAM, instead of needing a separate .c file.

0bd58a5613 esp8266/machine_pin: Move pin_intr_handler to iRAM, de-support hard IRQ.
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.

84fa3312cf all: Format code to add space after C++-style comment start.
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 helper function was added a while ago and these are the remaining
cases to convert, to save a bit of code size.

a3dc1b1957 all: Remove inclusion of internal py header files.
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.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
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.
