Summary:
Ref T9948. Ref T13546. To identify remote branch heads -- not just modified heads -- use "branchmap" like "hg outgoing" does.
I wasn't able to find any other way to get what we want: for example, with a bundlerepo, "peer.heads()" and "peer.changelog.heads()" include local branches which are not present in the remote.
It generally seems difficult (perhaps impossible?) to distinguish between these cases by using "getremotechanges()":
- branch X exists at position Y in both the local and remote;
- branch X exists at positino Y in the local, but not the remote.
In any case, this seems to work properly and //should// do less work than "getremotechanges()" since we don't need to pull as much data over the wire.
Test Plan: Ran "hg arc-ls-markers" in various repositories, got what appeared to be a faithful representation of the remote branch and bookmark state.

Summary:
Ref T9948. Ref T13546. This change moves toward a functional "arc land" in Mercurial.
Because of how "bundlerepo.getremotechanges()" works, "hg arc-ls-markers" does not actually list markers in the remote that aren't different from local markers so it's hard to get anywhere with this.
Test Plan: Got somewhat-encouraging output from "arc land" and "hg arc-ls-markers", but too many things are still broken for this to really work yet.

Summary: Ref T13546. Ref T9948. It seems challenging to examine a remote in vanilla Mercurial. Provide an "hg arc-ls-remote" command which functions like "git ls-remote" so we can figure out if "--into X" is a bookmark, branch, both, neither, or a branch with multiple heads without mutating the working copy as a side effect.
Test Plan: Ran various "arc land --into ..." commands in a Mercurial working copy, saw apparently-sensible resolution of remote marker names.
