mergestate: handle additional record types specially

This works around a bug in older Mercurial versions' handling of the v2 merge
state.

We also add a bunch of tests that make sure that
(1) we correctly abort when the merge state has an unsupported record type
(2) aborting the merge, rebase or histedit continues to work and clears out the
    merge state.
