If there are any free chunks found then it's better to sweep the filesystem
and use the available chunks, rather than error out with ENOSPC when there
is in fact a bit of space remaining.

The os.dupterm() function has changed on this port, it now matches the
semantics used by all other ports (except it's restricted to accept only
machine.UART objects).

Minor changes for consistency are:
- nrf gains: unique_id(), freq() [they do nothing]
- samd: deepsleep() now resets after calling lightsleep()
- esp32: lightsleep()/deepsleep() no longer take kw arg "sleep", instead
it's positional to match others. also, passing 0 here will now do a 0ms
sleep instead of acting like nothing was passed.
reset_cause() no longer takes any args (before it would just ignore them)
- mimxrt: freq() with an argument and lightsleep() both raise
NotImplementedError

And use it in all ports. The ports are unchanged, except esp8266 which now
just returns None from this function instead of the time elapsed (to match
other ports), and qemu-arm which gains this function.

This is a code factoring to have the dict for the machine module in one
location, and all the ports use that same dict. The machine.soft_reset()
function implementation is also factored because it's the same for all
ports that did already implement it. Eventually more functions/bindings
can be factored.
All ports remain functionally the same, except:
- cc3200 port: gains soft_reset, mem8, mem16, mem32, Signal; loses POWER_ON
(which was a legacy constant, replaced long ago by PWRON_RESET)
- nrf port: gains Signal
- qemu-arm port: gains soft_reset
- unix port: gains soft_reset
- zephyr port: gains soft_reset, mem8, mem16, mem32

MICROPY_PY_MACHINE_SPI is defined in mpconfigport.h to be equal to
MICROPY_PY_MACHINE_HW_SPI, so they are equivalent options. The former one
is preferred because it's used by all other ports.
The default in mpconfigport.h is to enable this option, and all boards that
enable SPI have this removed from their mpconfigboard.h file so they pick
up the default.

This is a code factoring to have the Python bindings in one location, and
all the ports use those same bindings. For all ports except the two listed
below there is no functional change.
The nrf port has UART.sendbreak() removed, but this method previously did
nothing.
The zephyr port has the following methods added:
- UART.init(): supports setting timeout and timeout_char.
- UART.deinit(): does nothing, just returns None.
- UART.flush(): raises OSError(EINVAL) because it's not implemented.
- UART.any() and UART.txdone(): raise NotImplementedError.

With public declarations moved to extmod/modmachine.h. It's now mandatory
for a port to define MICROPY_PY_MACHINE_PWM_INCLUDEFILE if it enables
MICROPY_PY_MACHINE_PWM. This follows how extmod/machine_wdt.c works.
All ports have been updated to work with this modified scheme.

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.

Changes in this commit:
- Move the pwm_seq array to the p_config data structure. That prevents
potential resource collisions between PWM devices.
- Rename the keyword argument 'id' to 'device'. That's consistent with the
SAMD port as the other port allowing to specify it.
Changes in this commit:
- Add the timeout and timeout_char keyword options.
- Make uart.read() non-blocking.
- Add uart.any().
- Add ioctl MP_STREAM_POLL handling.
- Change uart.write() into non-busy waiting. uart.write() still waits until
all data has been sent, but calls MICROPY_EVENT_POLL_HOOK while waiting.
uart.write() uses DMA for transfer. One option would be to add a small
local buffer, such that transfers up to the size of the buffer could be
done without waiting.
- As a side effect to the change of uart.write(), uart.txdone() and ioctl
flush now report/wait correctly for the end of transmission.
- Change machine_hard_uart_buf_t in machine_hard_uart_obj_t to an instance
of that struct, rather than a pointer to one.
These have the same frequency, but can have different duty cycle and
polarity.
pwm.deinit() stops all channels of a module, but does not release the
module. pwm.init() without arguments restarts all outputs.
Using extmod/machine_pwm.c for the Python bindings and the existing
softpwm.c driver, by just adding the interface.
Properties:
- Frequency range 1-3906 Hz.
- All PWM outputs run at the same frequency but can have different duty
cycles.
- Limited to the P0.x pins.
Since it uses the existing softpwm.c mechanism, it will be affected by
playing music with the music class.
This is a breaking change, making the hardware PWM on the nrf port
compatible with the other ports providing machine.PWM.
Frequency range 4Hz - ~5.4 MHz. The base clock range is 125kHz to 16 MHz,
and the divider range is 3 - 32767.
The hardware supports up to four outputs per PWM device with different duty
cycles, but only one output is (and was) supported.
So that it doesn't clash with the extmod version.
Also make the default for this enabled, so that most boards do not need to
configure it.

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".

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.

Since uart.write() of the nrf port waits until all bytes but the last
one have been sent, uart.flush() and uart.txdone() are implemented
as empty functions to provide API consistency.
uart.flush()
flush() will always return immediately, even if the last byte
may still be sent.
ret = uart.txdone()
uart.txdone() will always return True, even if the last byte
may still be sent.
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.
