A previous commit removed the unix-specific select module implementation
and made unix use the common one.
This commit adds an optimisation so that the system poll function is used
when polling objects that have a file descriptor. With this optimisation
enabled, if code registers both file-descriptor-based objects, and non-
file-descriptor-based objects with select.poll() then the following occurs:
- the system poll is called for all file-descriptor-based objects with a
timeout of 1ms
- then the bare-metal polling implementation is used for remaining objects,
which calls into their ioctl method (which can be in C or Python)
In the case where all objects have file descriptors, the system poll is
called with the full timeout requested by the caller. That makes it as
efficient as possible in the case everything has a file descriptor.
Benefits of this approach:
- all ports use the same select module implementation
- the unix port now supports polling of all objects and matches bare metal
implementations
- it's still efficient for existing cases where only files and sockets are
polled (on unix)
- the bare metal implementation does not change
- polling of SSL objects will now work on unix by calling in to the ioctl
method on SSL objects (this is required for asyncio ssl support)
Note that extmod/vfs_posix_file.c has poll disable when the optimisation is
enabled, because the code is not reachable when the optimisation is used.

The unix port has a custom select module which only works with objects that
have a file descriptor, eg files and sockets. On the other hand, bare
metal ports use the common extmod/modselect.c implementation of the select
module that supports polling of arbitrary objects, as long as those objects
provide a MP_STREAM_POLL in their ioctl implementation (which can be done
in C or Python).
This commit removes the unix-specific code and makes unix use the common
one provided by extmod/modselect.c instead. All objects with file
descriptors implement MP_STREAM_POLL so they continue to work.

The asyncio module now has much better CPython compatibility and
deserves to be just called "asyncio".
This will avoid people having to write `from uasyncio import asyncio`.
Renames all files, and updates port manifests to use the new path. Also
renames the built-in _uasyncio to _asyncio.

Previously sys.path could be modified by append/pop or slice assignment.
This allows `sys.path = [...]`, which can be simpler in many cases, but
also improves CPython compatibility.
It also allows sys.path to be set to a tuple which means that you can
clear sys.path (e.g. temporarily) with no allocations.
This also makes sys.path (and sys.argv for consistency) able to be disabled
via mpconfig. The unix port (and upytesthelper) require them, so they
explicitly verify that they're enabled.

This makes it so that sub-packages are resolved relative to their parent's
`__path__`, rather than re-resolving each parent's filesystem path.
The previous behavior was that `import foo.bar` would first re-search
`sys.path` for `foo`, then use the resulting path to find `bar`.
For already-loaded and u-prefixed modules, because we no longer need to
build the path from level to level, we no longer unnecessarily search
the filesystem. This should improve startup time.
Explicitly makes the resolving process clear:
- Loaded modules are returned immediately without touching the filesystem.
- Exact-match of builtins are also returned immediately.
- Then the filesystem search happens.
- If that fails, then the weak-link handling is applied.
This maintains the existing behavior: if a user writes `import time` they
will get time.py if it exits, otherwise the built-in utime. Whereas `import
utime` will always return the built-in.
This also fixes a regression from a7fa18c203
where we search the filesystem for built-ins. It is now only possible to
override u-prefixed builtins. This will remove a lot of filesystem stats
at startup, as micropython-specific modules (e.g. `pyb`) will no longer
attempt to look at the filesystem.
Added several improvements to the comments and some minor renaming and
refactoring to make it clearer how the import mechanism works. Overall
code size diff is +56 bytes on STM32.

This adds a mechanism to track a pending notify/indicate operation that
is deferred due to the send buffer being full. This uses a tracked alloc
that is passed as the content arg to the callback.
This replaces the previous mechanism that did this via the global pending
op queue, shared with client read/write ops.

This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.
Make all extmod variables (src, flags, etc) private to extmod.mk.
Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.
Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.

This conflicts with the triple-usage of these variables for user-C-modules

For CFLAGS_MOD, just use CFLAGS directly. For SRC, use SRC_C directly as
the relevant files are all guarded by the preprocessor anyway.

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.
Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
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".

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.
