This commit adds support for optional custom argument type validation to
argparse.ArgumentParser, allowing for shorter argument validation code
for both simple builtins and complex types.
For example, assuming that a particular command line argument must be an
integer, using "parser.add_argument('-a', type=int)" will make sure that
any value passed to that argument that cannot be converted into an
integer will trigger an argument validation error.

Commit 2ca1527321 optimized
`FileSection.skip()` for memory use. But that introduced a dependency on
the MicroPython-extension to stream read methods for an additional argument
specifying a maximum read size. This optimization meant that all file-like
objects passed into TarFile must support the extended 2-argument `readinto`
form.
This is problematic for at least two use cases:
1. Nested tar files, because `FileSetion` itself doesn't support 2-argument
`readinto`.
2. Using `mpremote mount` and reading a tar file from the remote mount,
which also doesn't support 2-argument `readinto`.
Instead of requiring all file-like objects to implement this extended form
of `readinto`, this commit changes `FileSection.skip()` so that it doesn't
use this form.
A test is added for this case which fails without the fix here.

Optimizations applied here are:
- writing once-used helper functions inline in their place of use
- writing once-used constant tuples inline in their place of use (I would
have used `from micropython import const` but that renders the code not
runnable under CPython for testing, and also increases code size itself
for the import)
- renamed _tmod to _t
- renamed _format to _fmt
- optimised timedelta._tuple() slightly
Reduces datetime.mpy by: 8897 -> 8728, so saves 169 bytes.

This commit applies the existing `localtz.patch` patch to add support for
naive datetime objects. That is, objects that don't have any info about
the current timezone.
This allows `datetime.datetime.now()` to work; prior to this patch it would
raise NotImplementedError.
Although we don't really have support for localtime vs gmtime on
bare-metal, ports such as the unix port and webassembly port do have this
distinction, and for them being able to do `datetime.datetime.now()` is
quite important (at least, that's what users expect to be able to do).
The associated unittest test has been updated.
This patch changes the size of datetime.mpy: 8466 -> 8897, so +431 bytes.

This implements a very basic `inspect.signature()` function.
At the moment it returns only a simple `Signature` instance with a
`parameters` attribute that holds an `OrderedDict` whose length matches the
arity of the input function (the number of arguments it takes).
So, the following code works and is compatible with CPython:
def f(a, b, *, c):
pass
print(len(inspect.signature(f).parameters))
That should print 3.

Although `Logger.exception` supports passing exception info with
`exc_info`, when you use `logging.exception` keyword arguments are not
forwarded to the root logger, which makes passing `exc_info` raise
`TypeError`.

When running tests from subfolders, import by "full dotted path" rather
than just module name, removing the need to add the test parent folder to
`sys.path`.
This matches CPython more closely, which places `abspath(top)` at the start
of `sys.path` but doesn't include the test file parent dir at all.
It fixes issues where projects may include a `test_xxx.py` file in their
distribution which would (prior to this change) be unintentionally found by
unittest-discover.

Since deque was removed from this repository the built-in one needs to be
used, and that doesn't have unbounded growth. So use a list instead, which
is adequate becasue contextlib only needs append and pop, not double ended
behaviour (the previous pure-Python implementation of deque that was used
here anyway used a list as its storage container).
Also tweak the excessive-nesting test so it uses less memory and can run on
the unix port.

This changes almost all uses of "u-module" to just "module" for the
following built-in modules:
- binascii
- collections
- errno
- io
- json
- socket
- struct
- sys
- time
There are some remaining uses of "u-module" naming, for the cases where the
built-in module is extended in Python, eg `python-stdlib/os` uses `uos`.
Also, there are remaining uses of `utime` when non-standard (compared to
CPython) functions are used, like `utime.ticks_ms()`.

This commit allows you to pass an exception object in as the exc_info kwarg
(CPython allows this), so logging exceptions can work even if the
MICROPY_PY_SYS_EXC_INFO option is disabled in the firmware.
Separately to that, currently even when sys.exc_info() is enabled, it's
only printing the traceback to _stream = sys.stderr - not to the configured
logging handlers. This means for instance if you've got a file log
handler it misses out on the tracebacks. That's also fixed in this commit.
