Try to make errors derive from RepositoryError if they can be the
result of malicious or malfunctioning remote repository: The idea
here is that client can handle just RepositoryError instead of
individual errors (as it cannot do anything about any of them).
Also improve variable naming.
This is backwards compatible.

exceptions.py is used from metadata.py: Annotating it is required if we
want to enable "no_untyped_call" in mypy.
The only change is UnsignedMetadataError: I would have removed argument
"signable" altogether but figured this is not worth breaking API. So
now "signable" is still not used for anything but it is now optional.

Extend MetaFile and TargetFile classes with methods
for length and hash verification. The common functionality
is implemented as static methods of the base class while
MetaFile and TargetFile implement the user API based on it.

This allows clients to separate
a) missing local repository and
b) error while loading local repository
This is fully backwards-compliant: MissingLocalRepositoryError derives
from RepositoryError and every situation that now results in
MissingLocalRepositoryError used to result in a RepositoryError.

Replace hard-coded logger names with __name__. For the most part this just uses
the standard conventions to create the same logger hierarchy as existed before.
The only real difference is that loggers created for printing during tests are
no longer part of the 'tuf' hierarchy.

for errors that use calculated error messages (like
ReplayedMetadataError).
Do this by adding __repr__() functions to the contained errors.
Additionally:
- adds repr funcs to some other exceptions that have str funcs
- fixes some minor style issues
- for reviewers, adds commented-out direct-reproduction code
to the repr() funcs.

and generate more friendly errors. Prior to this, a test in
test_updater.py was written in such a way to not actually be
testing whether or not specification version checking was
working correctly -- the error updater.py raised if a specification
version number was not supported was the same as would be raised
if a role version was not the expected version, and, amusingly,
the test could not distinguish between these two scenarios and
was providing the wrong role version......
Specification version mismatch now raises a particular error:
UnsupportedSpecificationError.
The specification version supported by this code is now also all
in one place, tuf.formats rather than tuf.updater.
Related error messages and testing were improved (with some
edge cases closed).

unnecessary pass statements in this situation, so this resolves that.

to extract hostname. After commit
"use a different session per hostname",
the code no longer raises MissingSchema if a URL is malformed in
certain cases. Since it parses URLs to extract the hostname and
would have raised securesystemslib.exceptions.FormatError, so the
test would have to check for that error instead of requests's
MissingSchema.
However, it's best to use a different error type, since while that
would be, true enough, a formatting error, FormatError is customarily
reserved for the automatic detection based on schemas in formats.py
(using <SCHEMA>.check_match()), and in any case it is not a
securesystemslib error.
So this commit adds error type tuf.exceptions.URLParsingError and
raises it if the hostname cannot be isolated in a URL, and checks
for it in test_download.py.
