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.

The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.
This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
to a mp_getiter_iternext_custom_t instance, which then defines both
getiter and iternext.
And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.
Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

This will always have the maximum/minimum size of a mp_obj_type_t
representation and can be used as a member in other structs.

The buffer protocol type only has a single member, and this existing layout
creates problems for the upcoming split/slot-index mp_obj_type_t layout
optimisations.
If we need to make the buffer protocol more sophisticated in the future
either we can rely on the mp_obj_type_t optimisations to just add
additional slots to mp_obj_type_t or re-visit the buffer protocol then.
This change is a no-op in terms of generated code.

When iterating over filesystem/folders with os.iterdir(), an open file
(directory) handle is used internally. Currently this file handle is only
closed once the iterator is completely drained, eg. once all entries have
been looped over / converted into list etc.
If a program opens an iterdir but does not loop over it, or starts to loop
over the iterator but breaks out of the loop, then the handle never gets
closed. In this state, when the iter object is cleaned up by the garbage
collector this open handle can cause corruption of the filesystem.
Fixes issues #6568 and #8506.
This is technically a breaking change, but:
a) We need the end handle to do descriptor discovery properly.
b) We have no possible use for the existing definition handle in the
characteristic result IRQ. None of the methods can use it, and therefore
no existing code should be using it in a way that changing it to a
different integer value should break.
Unfortunately NimBLE doesn't make it easy to get the end handle, so also
implement a mechanism to use the following characteristic to calculate
the previous characteristic's end handle.

Changes in this commit:
- Manifest include's now use the directory path where possible (no longer
necessary to include the manifest.py file explicitly).
- Add manifest.py for all drivers and components that are referenced by
port/board manifests.
- Replace all uses of freeze() with package()/module(), except for port and
board modules.
- Use opt=3 everywhere, for consistency and to reduce code size.
- Use require() instead of include() for all micropython-lib references.
- Remove support for optional board-level manifest.py in mimxrt port, to
make it behave the same as other ports (the board must set
FROZEN_MANIFEST to a custom manifest.py, which can optionally include the
default, port-level manifest).
- Also reinstates modules that were accidentally removed from the esp8266
512k build in fbe9417b90.

Previously the desired output type was specified. Now make the type part
of the function name. Because this function is used in a few places this
saves code size due to smaller call-site.
This makes `mp_obj_new_str_type_from_vstr` a private function of objstr.c
(which is almost the only place where the output type isn't a compile-time
constant).
This saves ~140 bytes on PYBV11.

Rather than drawing the entire boundary to catch missing pixels, just

Add method for drawing polygons.
For non-filled polygons, uses the existing line-drawing code to render
arbitrary polygons using the given coords list, at the given x,y position,
in the given colour.
For filled polygons, arbitrary closed polygons are rendered using a fast
point-in-polygon algorithm to determine where the edges of the polygon lie
on each pixel row.
Tests and documentation updates are also included.

Since commit e65d1e69e8 there is no longer an
io.FileIO class, so this option is no longer needed.
This option also controlled whether or not files supported being opened in
binary mode (eg 'rb'), and could, if disabled, lead to confusion as to why
opening a file in binary mode silently did the wrong thing (it would just
open in text mode if MICROPY_PY_IO_FILEIO was disabled).
The various VFS implementations (POSIX, FAT, LFS) were the only places
where enabling this option made a difference, and in almost all cases where
one of these filesystems were enabled, MICROPY_PY_IO_FILEIO was also
enabled. So it makes sense to just unconditionally enable this feature
(ability to open a file in binary mode) in all cases, and so just remove
this config option altogether. That makes configuration simpler and means
binary file support always exists (and opening a file in binary mode is
arguably more fundamental than opening in text mode, so if anything should
be configurable then it should be the ability to open in text mode).

This is useful in situations where the ThreadSafeFlag is reused and needs
to be cleared of any previous, unwanted event.
For example, clear the flag at the start of an operation, trigger the
operation (eg an I2C write), then (a)wait for an external event to set the
flag (eg a pin IRQ). Further events may trigger the flag again but these
are unwanted and should be cleared before the next cycle starts.
These were added in Python 3.5.
Enabled via MICROPY_PY_BUILTINS_BYTES_HEX, and enabled by default for all
ports that currently have ubinascii.
Rework ubinascii to use the implementation of these methods.

Instead of using the fixed machine_spi_type entity to get the SPI transfer
function, this transfer function is now extracted dynamically from the type
of the SPI object.
This allows the SPI object used to communicate with the WIZNET5K hardware
to be SoftSPI or hardware SPI, or anything that has the SPI protocol (at

Avoiding conflicts between the IRQ and an active transfers. Before this
change the device could lock up in heavy traffic situations.
Fix found and code supplied by @omogenot.
If nic.active(True) is called several times in a row, the device may lock
up. Even if that is bad coding practice, calling wiznet5k_deinit() in
wiznet5k_init() prevents the lock.
Drop an obsolete and wrong argument check, which prevented specifying a pin
for the interrupt signal. The proper checks are now done further down in
the code.
The ntptime module was previously only included in the ESP8266 port. This
commit factors that module out into the extmod directory, makes it support
different epochs, and includes it in the rp2 port.
On ports with more than one filesystem, the type will be wrong, for example
if using LFS but FAT enabled, then the type will be FAT. So it's not
possible to use these classes to identify a file object type.
Furthermore, constructing an io.FileIO currently crashes on FAT, and
make_new isn't supported on LFS.
And the io.TextIOWrapper class does not match CPython at all.

The device will respond to a non-WS request with a simple page that loads
websocket_content.js from a static host (http or https). However, even
if the resources are https, the page is still http and therefore allows
requesting to a WS (not WSS) websocket on the device.
Removed unused client_handshake from websocket_helper, and then merges the
remainder of this file (server_handshake) into webrepl.py (to reduce
firmware size). Also added the respond-as-HTTP handling to
server_handshake.
The default HTTP response is a simple page that sets the base URL and then
loads webrepl_content.js which document.write's the actual HTML.

This fixes two problems with the BTstack implementation of descriptor
discovery:
- The call to gatt_client_discover_characteristic_descriptors needs to have
value_handle set to the starting handle (actually characteristic handle)
to start the search from.
- The BTstack event for a descriptor query result is
GATT_EVENT_ALL_CHARACTERISTIC_DESCRIPTORS_QUERY_RESULT.
With this change the test tests/multi_bluetooth/ble_subscribe.py now passes
when BTstack is instance1 (for BTstack to pass as instance0 requires
gatts_write to support sending an update on BTstack).
