uctypes.FLOAT32 has a special value representation and
uctypes_struct_scalar_size() should be used instead of GET_SCALAR_SIZE().

This fixes a bug where double arguments on a 32-bit architecture would not
be passed correctly because they only had 4 bytes of storage (not 8).  It
also fixes a compiler warning/error in return_ffi_value on certian
architectures: array subscript 'double[0]' is partly outside array bounds
of 'ffi_arg[1]' {aka 'long unsigned int[1]'}.

Fixes issue #7064.

This adds to the ESP8266 tutorial instructions explaining which pins to
pull low to enter programming mode.

The number shown in the USB id is now the same as that returned by
machine.unique_id().  All 8 bytes are inserted as hex into the USB id.  A
usb id at /dev/serial/by-id then looks like:

    usb-MicroPython_Board_in_FS_mode_e469b03567342f37-if00

Doing "import <tab>" will now complete/list built-in modules.

Anything beginning with "_" will now only be tab-completed if there is
already a partial match for such an entry.  In other words, entering
foo.<tab> will no longer complete/list anything beginning with "_".

This is provide by a few ports now, and is very useful.

This adds an initial specification of the machine.PWM class, to provide a
way to generate PWM output that is portable across the different ports.
Such functionality may already be available in one way or another (eg
through a Timer object), but because configuring PWM via a Timer is very
port-specific, and because it's a common thing to do, it's beneficial to
have a top-level construct for it.

The specification in this commit aims to provide core functionality in a
minimal way.  It also somewhat matches most existing ad-hoc implementations
of machine.PWM.

See discussion in #2283 and #4237.

These commented-out lines of code have been unused for a long time, so
remove them to avoid confusion as to why they are there.

mp_obj_dict_free() never existed, this line was converted from
mp_map_deinit() and commented out as soon as it was added.  The call to
mp_map_deinit(mp_loaded_modules_map) was commented in
1a1d11f.

Fixes issue #3507.
