repod/config/settings.py:
Add the top-level validator function `validate_directory()` instead of
relying on a Directory model and a pydantic validator. This way it is
possible to set a default for ManagementRepo.directory.
Remove unneeded Directory model.

tests/config/test_settings.py:
Adapt tests for `Directory.validate_directory()` for
`validate_directory()`.

There were multiple shortcomings with the current implementation
compared to the behavior of the official libalpm implementation. One of
the primary differences requires a version segment to be handled chunk
by chunk whether its numeric or none numeric. Furthermore differences in
segment separators (none alpha-numeric characters) requires special
handling to get the same results as libalpm.

As there are just too many edge cases this changes implements the
original libalpm vercmp algorithm as is.

Furthermore move everything out of `models.py` into an own version
module which is included. This will make it tremendously easier to
potentially support multiple version schemas for different consumers in
the future.

Fixes #63

tests/common/test_regex.py:
Test against valid/invalid compression type fixtures in regular
expression tests.

tests/conftest.py:
Add session wide fixtures for valid/ invalid compression types.

repod/common/enums.py:
Change return value of `tar_compression_types_for_filename_regex()` to
properly match dot prefixed file endings (e.g. `.gz`) and not any other
prefix character.

tox.ini:
Increase the verbosity of integration test runs again.

tests/files/test_{buildinfo,mtree}.py:
Lookup local packages for tests in a compression type agnostic fashion
(using all supported compression types).

It's nice to support both modules that stand in conflict with each
other. Instead of forcing a specific implementation, we instead provide
a tiny compatibility check and act differently while loading the string
representation of the file type.

repod/common/enums.py:
Improve the documentation for CompressionTypeEnum to reflect that it is
now a string based enum with values representing possible file suffixes.

repod/config/settings.py:
Remove the leading underscore from all config helper functions. It
serves no purpose and they are not exposed when importing from
repod.config.

repod/config/settings.py:
Use `repod.config.defaults.MANAGEMENT_REPO` as default directory for the
`ManagementRepo` model.

repod/models/config.py:
Remove config models, as they are now part of repod.config.settings.

Remove exposure of (now non-existent) config models.

tests/test_models.py:
Remove tests for config models.

repod/config/settings.py:
Copy `Architecture`, `Directory`, `ManagementRepo`, `PackagePool`,
`PackageRepo`, `SourcePool` to repod.config.settings as they are only
used in that context.

tests/config/test_settings.py:
Copy tests for added models.

repod/config/__init__.py:
Add init file to expose the `repod.config.settings.Settings`.

repod/config/settings.py:
Turn imports from `repod.config.defaults` and `repod.models` into
top-level imports.

repod/files/__init__.py:
Turn imports from `repod.config.defaults` into top-level imports.

tests/config/test_config.py:
Adapt import location for `repod.config.settings`.

Move the configuration related files config.py and defaults.py to a
dedicated config module to be able to expose only parts of the
functionality when importing it.
Move tests to dedicated location for config.

docs/packages/contents.rst:
Add documentation about .PKGINFO files, including JSON schema for
PkgInfo.

tox.ini:
Also export the PkgInfo JSON schema when creating documentation.

repod/files/pkginfo.py:
Add a .PKGINFO parser, which fully validates files of version 1 and of
version 2 (with pkgtype).

tests/files/test_pkginfo.py:
Add unit and integration tests for .PKGINFO parser.

repod/common/enums.py:
Add `PkgTypeEnum` to distinguish different types of pkgtype values.
Add `pkg_types_for_pkgtype_regex()` to provide a string for the PKGTYPE
regular expression.

repod/common/regex.py:
Add the `PKGTYPE` regular expression, which makes use of
`repod.common.enums.pkg_types_for_pkgtype_regex`.

tests/common/test_regex.py:
Add tests for PKGTYPE regular expression.

Also install poetry so that all required packages can be installed using
tox and poetry.

repod/common/models.py:
Attempt to import pyalpm's `vercmp()` and use it in `PkgVer.vercmp()`
and `Version.vercmp()` instead of the builtin implementation if it is
available.

tests/common/test_models.py:
Parametrize tests for `PkgVer.vercmp()` and `Version.vercmp()` further
so that they can run against pyalpm's `vercmp()` and the builtin
implementation.

tox.ini:
Call poetry in tox.ini again, as this way we can ensure to install
all packages based on the lock file.
Additionally, this allows to properly and selectively install extras,
required e.g. by the coverage target (as to not install pyalpm for all
targets).

instance method.
Add helper methods `get_epoch()`, `get_pkgrel()` and `get_pkgver()` to
the `Version` model to be able to retrieve the respective subsets.
Add native `vercmp()` method to `Version` model to allow comparison
amongst instances of the model.
