And make it so this test can run on any target.
LED and time testing has been removed from this test, that can now be
tested using: ./run-tests.py --via-mpy --emit native.

If a port is not using internal error numbers, which match both lwIP and
Linux error numbers, ENTOCONN from standard libraries errno.h equals 128,
not 107.

This enables the new `-X realtime` runtime option when running tests on
macOS. This causes MicroPython to configure all threads to be high
priority so that they are allowed to use high precision timers. This
makes tests that depend on the passage of time more likely to succeed.
CI tests that were disabled because of this are now enabled again.

This adds support for the `--via-mpy` and `--emit native` options when
running tests on remote targets (via pyboard.py). It's now possible to do:
$ ./run-tests.py --target pyboard --via-mpy
$ ./run-tests.py --target pyboard --via-mpy --emit native

Now that constant tuples are supported in the parser, eg (1, True, "str"),
it's a small step to allow anything that is a constant to be used with the
pattern:
from micropython import const
X = const(obj)
This commit makes the required changes to allow the following types of
constants:
from micropython import const
_INT = const(123)
_FLOAT = const(1.2)
_COMPLEX = const(3.4j)
_STR = const("str")
_BYTES = const(b"bytes")
_TUPLE = const((_INT, _STR, _BYTES))
_TUPLE2 = const((None, False, True, ..., (), _TUPLE))
Prior to this, only integers could be used in const(...).

Because the test modifies the (now) bytearray object, and if it's a bytes
object it's not guaranteed that it can be modified, or that this constant
object isn't used elsewhere.

Prior to this commit, all qstrs were required to be allocated (by calling
mp_emit_common_use_qstr) in the MP_PASS_SCOPE pass (the first one). But
this is an unnecessary restriction, which is lifted by this commit.
Lifting the restriction simplifies the compiler because it can allocate
qstrs in later passes.
This also generates better code, because in some cases (eg when a variable
is closed over) the scope of an identifier is not known until a bit later
and then the identifier no longer needs its qstr allocated in the global
table.
Code size is reduced for all ports with this commit.

Prior to this commit, even with unicode disabled .py and .mpy files could
contain unicode characters, eg by entering them directly in a string as
utf-8 encoded.
The only thing the compiler disallowed (with unicode disabled) was using
\uxxxx and \Uxxxxxxxx notation to specify a character within a string with
value >= 0x100; that would give a SyntaxError.
With this change mpy-cross will now accept \u and \U notation to insert a
character with value >= 0x100 into a string (because the -mno-unicode
option is now gone, there's no way to forbid this). The runtime will
happily work with strings with such characters, just like it already works
with strings with characters that were utf-8 encoded directly.
This change simplifies things because there are no longer any feature
flags in .mpy files, and any bytecode .mpy will now run on any target.

This commit adds support to the parser so that tuples which contain only
constant elements (bool, int, str, bytes, etc) are immediately converted to
a tuple object. This makes it more efficient to use tuples containing
constant data because they no longer need to be created at runtime by the
bytecode (or native code).
Furthermore, with this improvement constant tuples that are part of frozen
code are now able to be stored fully in ROM (this will be implemented in
later commits).
Code size is increased by about 400 bytes on Cortex-M4 platforms.
See related issue #722.

There were two issues with the existing code:
1. "1 << i" is computed as a 32-bit number so would overflow when
executed on 64-bit machines (when mp_uint_t is 64-bit). This meant that
*args beyond 32 positions would not be handled correctly.
2. star_args must fit as a positive small int so that it is encoded
correctly in the emitted code. MP_SMALL_INT_BITS is too big because it
overflows a small int by 1 bit. MP_SMALL_INT_BITS - 1 does not work
because it produces a signed small int which is then sign extended when
extracted (even by mp_obj_get_int_truncated), and this sign extension
means that any position arg after *args is also treated as a star-arg.
So the maximum bit position is MP_SMALL_INT_BITS - 2. This means that
MP_OBJ_SMALL_INT_VALUE() can be used instead of
mp_obj_get_int_truncated() to get the value of star_args.
These issues are fixed by this commit, and a test added.

This fixes code coverage for the case where a *arg without __len__ is
unpacked and uses exactly the amount of memory that was allocated for
kw args. This triggers the code branch where the memory for the kw args
gets reallocated since it was used already by the *arg unpacking.

This is a partial implementation of PEP 448 to allow unpacking multiple
star args in a function or method call.
This is implemented by changing the emitted bytecodes so that both
positional args and star args are stored as positional args. A bitmap is
added to indicate if an argument at a given position is a positional
argument or a star arg.
In the generated code, this new bitmap takes the place of the old star arg.
It is stored as a small int, so this means only the first N arguments can
be star args where N is the number of bits in a small int.
The runtime is modified to interpret this new bytecode format while still
trying to perform as few memory reallocations as possible.

This is a partial implementation of PEP 448 to allow multiple ** unpackings
when calling a function or method.
The compiler is modified to encode the argument as a None: obj key-value
pair (similar to how regular keyword arguments are encoded as str: obj
pairs). The extra object that was pushed on the stack to hold a single **
unpacking object is no longer used and is removed.
The runtime is modified to decode this new format.

The following fixes are made:
- cancelling a gather now cancels all sub-tasks of the gather (previously
it would only cancel the first)
- if any sub-task of a gather raises an exception then the gather finishes
(previously it would only finish if the first sub-task raised)
Fixes issues #5798, #7807, #7901.
