If you follow the instructions we provide for our contributors in
docs/CONTRIBUTORS.rst your sys.path (used to search for imports)
will put securesystemlib project directory first and tuf directory
second.
This creates a problem with imports from tuf modules because we can
import the wrong file or on relative imports (as currently we
use in the tests when we import utils), the imports cannot be resolved.
If we change the installation order, then tuf directory will be the
first in the import resolution path and those problems will be fixed.
PS: I want to express my gratitude towards Jussi who helped me find
this problem.

Use Google style guide with refinements, because the Google style
guide is a comprehensive, well-established style guide that is
mostly based on PEP-8 and was accepted by everyone on the TUF team.
There is no need to replicate these recommendations. However, we do
provide a very slim document with additional refinements, in order
to emphasize on items the we consider especially important, want to
be handled differently, or in one specific way, where the Google
guide would allow multiple.

secure-systems-lab/securesystemslib#288 changes the key generation
interface functions in such a way that it is clear if a call opens
a blocking prompt, or writes the key unencrypted. To do this two
functions are added per key type:
- `generate_and_write_*_keypair_with_prompt`
- `generate_and_write_unencrypted_*_keypair`
The default `generate_and_write_*_keypair` function now only allows
encrypted keys and only using a passed password. This respects the
principle of secure defaults and least surprise.
sslib#288 furthermore adds a protected
`_generate_and_write_*_keypair`, which is not exposed publicly
because it does not encrypt by default, but is more flexible and
thus convenient e.g. to consume all arguments from a key generation
command line tool such as 'repo.py'.
This commit adds the new public functions to the tuf namespace and
adopts their usage accordingly.
NOTE regarding repo.py:
This commit does not fix any problematic password behavior of
'repo.py' like default passwords, etc. (see #881). It only adopts
the sslib#288 changes to maintain the current behvior, plus
removing one glaringly obsolete password prompt.
NOTE regarding key import:
The securesystemslib private key import functions were also changed
to no longer auto-prompt for decryption passwords , TUF, however,
only exposes custom wrappers (see repository_lib) that do
auto-prompt. sslib#288 changes to the prompt texts are nevertheless
propagated to tuf and reflected in this commit.

In order to make decisions about the code and the design explicit and easier
to reference in future we want to record significant architectural decisions.
This commit introduces docs/adr with a template Architectural Decision Record
and index using the [MADR](https://adr.github.io/madr/) format.
It also adds ADR 0000 to document the decisions to use MADR.

* Use suffixed instead of prefixed sub-requirements files to group
them alphabetically in the file tree.
* Layer requirements files akin to the in-toto project
(see in-toto/in-toto#294). The hierarchy is:
- *requirements.in*
tuf runtime requirements, including optional requirements
(pynacl and cyrptography)
- *requirements-pinned.txt*
pinned tuf runtime requirements, including optional
and transitive (1 level deep) requirements and their hashes.
The file is generated semi-automatically using pip-compile
and a bash script (see document header), based off of
requirements.in, combining requirements from all supported
Python versions.
This file should be auto-updated, by e.g. dependabot, and be used
for ci/cd tests, to catch issues with new dependencies.
- *requirements-test.txt*
additional test runtime requirements
- *requirements-tox.txt*
combines requirements.txt, requirements-test.txt and additional
test tools (for linting and coverage), i.e. everything that is
needed in each tox environment to run the tests.
- *requirements-dev.txt*
lists tox for local development and testing, and also
requirements-tox.txt and tuf in editable mode to run
the test suite or individual tests directly.
- *requirements.txt*
requirements-pinned.txt with the hashes of the dependencies
as reported by pip at the time of creating the file.
NOTE: this is not used for testing or dev-install because pip
doesn't allow mixed (with and without hashes) installations.
This file should also be auto-updated, by e.g. dependabot.
* Removes an obsolete version constraint on coverage

TUF does not reliably mark roles as dirty whose metadata needs
to be re-generated.
Only roles that have changed are marked as dirty, but sometimes
roles metadata needs to be updated, although the role wasn't
changed directly (see #958).
Furthermore, the tutorial assumes at one point that the reader
leaves and re-enter the interpreter session, being forced to reload the
signing keys, roles that later need to be re-written, are marked as
dirty. If the reader does not leave the interpreter, the roles are
not marked as dirty (see #964).
To not confuse the reader with flawed state-keeping, and to never
write an inconsistent repository to disk, the tutorial lets the
reader explicitly mark all roles that need to be re-written as
"dirty".
This can be changed once above issues are fixed.
