treemanifest: add configuration for using treemanifest type

This change adds boolean configuration option
experimental.treemanifest. When the option is enabled, manifests are
parsed into the new treemanifest type.

Tests can be now run using treemanifest by switching the config option
default in localrepo._applyrequirements(). Tests pass even when made
to randomly choose between manifestdict and treemanifest, suggesting
that the two types produce identical manifests (so e.g. a manifest
revlog entry written from a treemanifest can be parsed by the
manifestdict code).
