While at it, also remove unnecessary "#!/usr/bin/env python3" in files
that only get imported, and adjust other empty/comment lines in the
beginnings of the files for consistency.
This makes files easier to read, and makes the pmbootstrap codebase more
consistent with the build.postmarketos.org codebase.
Compare a version against a check string. This will be used in
"pmbootstrap kconfig check", to only require certain options if the
pkgver is in a specified range.
Python < 3.6 randomized the order of keys in dictionaries, unless
OrderedDict was used. Use OrderedDict to store the version suffixes.
When the order was randomized, the valid version string 3.0.0_pre1 did
not always pass the validation check. The suffix "pre" should always be
detected as such, but with the random order, it was sometimes detected
as "p" suffix (see below). The following letters "re" are not a valid
suffix_no (the number expected to follow the suffix) and so it failed.
suffixes = {
"pre": ["pre", ...],
"post": ["p". ...]
}
Previously, distutils.version.LooseVersion was used, because it was
sort of close enough to how Alpine parses versions.
This new version uses the exact same algorithm, as `apk` does, and
it passes *all* of `apk`'s testcases for version checking (previously
we simply skipped the ones, that did not pass).
* Remove pmb/helpers/version.py left-over (it is in parse now)
* Make asserts consistent, do not use unnecessary parenthesis
