testify makes most bog-standard test checks much easier to read and
maintain, and is quite widely used. It wasn't really well known back
when go-mtree was first written, but the migration is fairly
straight-forward for most tests.

This was added in Go 1.15 and avoids polluting the host /tmp with test
directories if the test crashes or is forcefully killed.

In certain circumstances (such as the manifest generation of a
filesystem as an unprivileged user) it is important to provide hooks
that override the default os.* implementation of filesystem-related
functions.
In order to avoid merging too much code from outside projects (such as
umoci) this is implemented by providing FsEval hooks to Walk() and
Check(). This allows for users of go-mtree to modify how filesystem
checks are done, without compromising the simplicity of go-mtree's code.

While the full testing is broken due to bugs in the tar DH generator, we
ignore known bugs in the tar generator to at least allow us to test some
of the other semantics of Compare.

This is part of a patchset that refactors all of the checking logic into
comparison operations. Essentially, provide a Compare(...) function that
allows for two different manifests to be compared. Extra and missing
entries are supported in addition to the standard modified entry, and by
implementing as a manifest comparison there is no double-scanning of the
manifest source.
The main annoyance is that we have to also include tar_time handling,
which has not been abstracted inside keywords.go. This is a bit ugly
right now, but works fine for the moment.
