Find a distribution and all distributions it depends on.
:param requirement: The requirement specifying the distribution to
find, or a Distribution instance.
:param meta_extras: A list of meta extras such as :test:, :build: and
so on.
:param prereleases: If ``True``, allow pre-release versions to be
returned - otherwise, don't return prereleases
unless they're all that's available.
Return a set of :class:`Distribution` instances and a set of
problems.
The distributions returned should be such that they have the
:attr:`required` attribute set to ``True`` if they were
from the ``requirement`` passed to ``find()``, and they have the
:attr:`build_time_dependency` attribute set to ``True`` unless they
are post-installation dependencies of the ``requirement``.
The problems should be a tuple consisting of the string
``'unsatisfied'`` and the requirement which couldn't be satisfied
by any distribution known to the locator.
