Rather than drawing the entire boundary to catch missing pixels, just
detect the cases where boundary pixels are skipped during node calculation
and pre-emptively draw them then.
This adds 72 bytes on PYBV11, but makes filled poly() 20% faster.

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.

Rework the conversion of floats to decimal strings so it aligns precisely
with the conversion of strings to floats in parsenum.c. This is to avoid
rendering 1eX as 9.99999eX-1 etc. This is achieved by removing the power-
of-10 tables and using pow() to compute the exponent directly, and that's
done efficiently by first estimating the power-of-10 exponent from the
power-of-2 exponent in the floating-point representation.
Code size is reduced by roughly 100 to 200 bytes by this commit.

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.
This commit adds the bytes methods to bytearray, matching CPython. The
existing implementations of these methods for str/bytes are reused for
bytearray with minor updates to match CPython return types.
For details on the CPython behaviour see
https://docs.python.org/3/library/stdtypes.html#bytes-and-bytearray-operations
The work to merge locals tables for str/bytes/bytearray/array was done by
@jimmo. Because of this merging of locals the change in code size for this

Binaries built using the Make build system now no longer appear in the
working directory of the build, but rather in the build directory. Thus
some paths had to be adjusted.
The reallocation trigger for unpacking star args with unknown length
did not take into account the number of fixed args remaining. So it was
possible that the unpacked iterators could take up exactly the memory
allocated then nothing would be left for fixed args after the star args.
This causes a segfault crash.
This is fixed by taking into account the remaining number of fixed args
in the check to decide whether to realloc yet or not.

Formerly, py/formatfloat would print whole numbers inaccurately with
nonzero digits beyond the decimal place. This resulted from its strategy
of successive scaling of the argument by 0.1 which cannot be exactly
represented in floating point. The change in this commit avoids scaling
until the value is smaller than 1, so all whole numbers print with zero
fractional part.
Fixes issue #4212.

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.

This commit simplifies mp_obj_get_complex_maybe() by first calling
mp_obj_get_float_maybe() to handle the cases corresponding to floats.
Only if that fails does it attempt to extra a full complex number.
This reduces code size and also means that mp_obj_get_complex_maybe() now
supports user-defined classes defining __float__; in particular this allows
user-defined classes to be used as arguments to cmath-module function.
Furthermore, complex_make_new() can now be simplified to directly call
mp_obj_get_complex(), instead of mp_obj_get_complex_maybe() followed by
mp_obj_get_float(). This also improves error messages from complex with
an invalid argument, it now raises "can't convert <type> to complex" rather
than "can't convert <type> to float".

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 new logic tracks when an unconditional jump/raise occurs in the
emitted code stream (bytecode or native machine code) and suppresses all
subsequent code, until a label is assigned. This eliminates a lot of
cases of dead code, with relatively simple logic.
This commit combined with the previous one (that removed the existing
dead-code finding logic) has the following code size change:

Support for architecture-specific qstr linking was removed in
d4d53e9e11, where native code was changed to
access qstr values via qstr_table. The only remaining use for the special
qstr link table in persistentcode.c is to support native module written in
C, linked via mpy_ld.py. But native modules can also use the standard
module-level qstr_table (and obj_table) which was introduced in the .mpy
file reworking in f2040bfc7e.
This commit removes the remaining native qstr liking support in
persistentcode.c's load_raw_code function, and adds two new relocation
options for constants.qstr_table and constants.obj_table. mpy_ld.py is
updated to use these relocations options instead of the native qstr link
table.
