wireproto: port heads command to wire protocol v2...

wireproto: port heads command to wire protocol v2 After much thought and consideration, wire protocol version 2's commands will be defined in different functions from the existing commands. This will make it easier to implement these commands because it won't require shoehorning things like response formatting and argument declaration into the same APIs. For example, wire protocol version 1 requires that commands declare a fixed and ordered list of argument names. It isn't really possible to insert new arguments or have optional arguments without breaking backwards compatibility. Wire protocol version 2, however, uses CBOR maps for passing arguments. So arguments a) can be optional b) can be added without BC c) can be strongly typed. This commit starts our trek towards reimplementing the wire protocol for version 2 with the heads command. It is pretty similar to the existing heads command. One added feature is it can be told to operate on only public phase changesets. This is useful for making discovery faster when a repo has tens of thousands of draft phase heads (such as Mozilla's "try" repository). The HTTPv2 server-side protocol has had its `getargs()` implementation updated to reflect that arguments are a map and not a list. Differential Revision: https://phab.mercurial-scm.org/D3179
