Quite regularly users complain about unexpected behavior of I2C, calling it
a bug, when in fact the trouble is caused by missing pull-up resistors. So
this commit adds a note to the documentation, in the slim hope that people
will find and read it.
* `init()` can be called multiple times to reconfigure UART.
* After `deinit()` it is impossible to call `init()` again.

Updated some of the CPython feature differences:
- Updated status of some features.
- Added CSS to fix table widths to 100% and word wrap.
- Specified explicit table column ratios to improve layout appearance.
- Added missing references to anchors.
- Better consistency with use of formatting and case.
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.

We plan to add `ellipse` and `poly` methods, but rather than having to
implement a `fill_xyz` version of each, we can make them take an optional
fill argument. This commit add this to `rect` as a starting point.

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.
The separate A and RM toolchains have been discontinued and replaced
by a single toolchain. This updates the links to the RM toolchain to
the new toolchain.

Document how to connect the Timer block BRK_IN to a physical Pin alternate
function.
Add an example of PWM Motor drive using complementary outputs with dead
time and break input to kill the PWM and generate a callback.

Some Pin alternate functions are inputs, for example, timer capture and
break inputs. In Pyb.Pin the only way to set alt mode is with Pin.AF_PP or
Pin.AF_OD. It is not intuitive to use an output mode to configure an
input. Pin.ALT is used in the machine.Pin class and works in pyb.Pin.
The examples are changed to use Pin.ALT because TIM2_CH3 can be a capture
input or pulse output.

Remove out of context callback paragraph, it was part of the wipy docs.
And move the paragraph about PULL_UP/PULL_DOWN resistor values to within
the init() method docs. Also fix pull-pull -> push-pull.

Add cert_reqs and cadata keyword-args to ssl.wrap_socket() and
ssl.CERT_NONE, ssl.CERT_OPTIONAL, ssl.CERT_REQUIRED constants to allow
certificate validation.
CPython doesn't accept cadata in ssl.wrap_socket(), but it does in
SSLContext.load_verify_locations(), so we use this name to at least match
the same name in load_verify_locations().
Add docs for these new arguments, as well as docs for the existing
server_hostname argument which is important for certificate validation.
Tests are added as well.

This uses MP_REGISTER_ROOT_POINTER() to register the readline_history root
pointer array used by shared/readline.c and removes the registration from
all mpconfigport.h files.
This also required adding a new MICROPY_READLINE_HISTORY_SIZE config option
since not all ports used the same sized array.

Add esp32.wake_on_ulp() to give access to esp_sleep_enable_ulp_wakeup(),
which is needed to allow the ULP co-processor to wake the main CPU from
deep sleep.
This changes the btree implementation to use the buffer protocol for
reading key/values in all methods. `str` and `bytes` objects are not the
only bytes-like objects that could be used.
Documentation and tests are also updated.
Addresses issue #8748.

This separates extmod source files from `py.mk`. Previously, `py.mk`
assumed that every consumer of the py/ directory also wanted to include
extmod/. However, this is not the case. For example, building mpy-cross
uses py/ but doesn't need extmod/.
This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and
explicitly includes `extmod.mk` in ports that use it.

It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.
