If a multitest calls `multitest.output_metric(...)` then that output will
be collected separately, not considered as part of the test verification
output, and instead be printed at the end. This is useful for tests that
want to output performance/timing metrics that may change from one run to
the next.

When iterating over os.ilistdir(), the special directories '.' and '..'
are filtered from the results. But the code inadvertently also filtered
any file/directory which happened to match '..*'. This change fixes the
filter.

When := is used in a comprehension the target variable is bound to the
parent scope, so it's either a global or a nonlocal. Prior to this commit
that was handled by simply using the parent scope's id_info for the
target variable. That's completely wrong because it uses the slot number
for the parent's Python stack to store the variable, rather than the slot
number for the comprehension. This will in most cases lead to incorrect
behaviour or memory faults.
This commit fixes the scoping of the target variable by explicitly
declaring it a global or nonlocal, depending on whether the parent is the
global scope or not. Then the id_info of the comprehension can be used to
access the target variable. This fixes a lot of cases of using := in a
comprehension.

Prior to this fix, pow(1.5, inf) and pow(0.5, -inf) (among other things)
would incorrectly raise a ValueError, because the result is inf with the
first argument being finite. This commit fixes this by allowing the result
to be infinite if the first or second (or both) argument is infinite.
This fix doesn't affect the other three math functions that have two
arguments:
- atan2 never returns inf, so always fails isinf(ans)
- copysign returns inf only if the first argument x is inf, so will never
reach the isinf(y) check
- fmod never returns inf, so always fails isinf(ans)

32-bit platforms only support a slice offset start of 24 bit max due to the
limited size of the mp_obj_array_t.free member. Similarly on 64-bit
platforms the limit is 56 bits.
This commit adds an OverflowError if the user attempts to slice a
memoryview beyond this limit.

In @micropython.native code the types of variables and expressions are
always Python objects, so they can be initialised as such. This prevents
problems with compiling optimised code like while-loops where a local may
be referenced before it is assigned to.

During the initial handshake or subsequent renegotiation, the protocol
might need to read in order to write (or conversely to write in order
to read). It might be blocked from doing so by the state of the
underlying socket (i.e. there is no data to read, or there is no space
to write).
The library indicates this condition by returning one of the errors
`MBEDTLS_ERR_SSL_WANT_READ` or `MBEDTLS_ERR_SSL_WANT_WRITE`. When that
happens, we need to enforce that the next poll operation only considers
the direction that the library indicated.
In addition, mbedtls does its own read buffering that we need to take
into account while polling, and we need to save the last error between
read()/write() and ioctl().
The assertion that is added here (to gc.c) fails when running this new test
if ALLOC_TABLE_GAP_BYTE is set to 0.

The code was already checking for duplicate kwargs for named parameters but
if `**kwargs` was given as a parameter, it did not check for multiples of
the same argument name.
This fixes the issue by adding an addition test to catch duplicates and
adds a test to exercise the code.

Allows optimisation of cases like:
import micropython
_DEBUG = micropython.const(False)
if _DEBUG:
print('Debugging info')
Previously the 'if' statement was only optimised out if the type of the
const() argument was integer.
The change is implemented in a way that makes the compiler slightly smaller
(-16 bytes on PYBV11) but compilation will also be very slightly slower.
As a bonus, if const support is enabled then the compiler can now optimise
const truthy/falsey expressions of other types, like:
while "something":
pass
... unclear if that is useful, but perhaps it could be.

Prevent handle leaks when file objects aren't closed explicitly and
fix some MICROPY_CPYTHON_COMPAT issues: this wasn't properly adhered
to because #ifdef was used so it was always on, and closing files
multiple times should be avoided unconditionally.
This matches class `__dict__`, and is similarly gated on
MICROPY_CPYTHON_COMPAT. Unlike class though, because modules's globals are
actually dict instances, the result is a mutable dictionary.
