fnmatch() will do case-normalization if the OS expects it:
we do not want this as
* the path is more a URL than a file path
* results need to not change based on OS
Fix the result on Windows by using fnmatchcase()

We could just stop testing with 3.9... but I think this will lead to
unintentionally breaking 3.9 anyway sooner or later.

securesystemslib.hash is a small wrapper around hashlib, which serves
two main purposes:
* provide helper function to hash a file
* translate custom hash algorithm name "blake2b-256" to "blake2b" with
(digest_size=32).
In preparation for the removal of securesystemslib.hash, this patch ports
above behavior to tuf and uses the builtin hashlib directly where
possible.

Update test_updater_toplevel_update to use bootstrap argument by
default.
This still does not include tests for bootstrap feature specifically
but it should prove nothing has broken when the feature was added.

Application may have a "more secure" data store than the metadata cache
is: Allow application to bootstrap the Updater with this more secure
root. This means the Updater must also cache the subsequent root versions
(and not just the last one).
* Store versioned root metadata in local cache
* maintain a non versioned symlink to last known good root
* When loading root metadata, look in local cache too
* Add a 'bootstrap' argument to Updater: this allows
initializing the Updater with known good root metadata
instead of trusting the root.json in cache
Additional changes to current functionality:
* when using bootstrap argument, the initial root is written to cache.
This write happens every time Updater is initialized with bootstrap
* The "root.json" symlink is recreated at the end of every refresh()

This does not actually test using tuf through proxies: it only tests
that ProxyEnvironment creates the ProxyManagers that we expect to be
created based on the proxy environment variables.

urllib3 does not handle this but we do want to support proxy users.
The environment variable handling is slightly simplified from the
requests implementation.

This is still copy-paste in three different files but now at least
the function is the same in every location and not directly copied.
We really should have generic TestCase class...

test_updater_ng.py is a little archaic (as it uses the static test
repository content from ye olden days). This commit does not change that
but removes an extra file in client cache dir: it is now quite confusing
as it looks a bit like intermediate root caching but is just an unused
file.
This has the nice side effect that tests now longer need to workaround
this extra file.

This allows using some more nice annotations from 3.10
while still being compatible with even Python 3.8.
These are all annotation changes, should not modify any functionality.

Use freezegun for time mocking instead of manually patching the datetime
module, as it provides a more streamlined solution that works both
on CPython and on PyPy. Unfortunately, due to differences between
the C datetime extension used by CPython, and the pure Python version
of datetime (used by PyPy, and as a fallback on CPython), there does not
seem to be a trivial way to mock time that would work with both
versions.

The goal here is to have ruff enable new rulesets when new releases are
made without us having to o anything: we can then decide if we disable
or not.
* Enable a couple more rulesets (ERA, INP, T )
* Add a few individual ignores to tests and examples
* Default to enable all, disable the rulesets we don't want
