bundle: avoid repo.lookup() for converting revnum to nodeid Differential Revision: https://phab.mercurial-scm.org/D3048

push: avoid using repo.lookup() for converting to nodeid repo.lookup(x) currently simply does repo[x].node(), which supports various types of inputs. As I explained in 0194dac77c93 (scmutil: add method for looking up a context given a revision symbol, 2018-04-02), I'd like to split that up so we use the new scmutil.revsymbol() for string inputs repo[x] for integer revnums and binary nodeids. Since repo.lookup() seems to exist in order to serve peer.lookup(), I think it should be calling revsymbol. However, we have several callers that use repo.lookup() with something that's not a string, so we need to remove those first. This patch starts doing that. Many more will follow.

addremove: pass command-level similarity value down to scmutil.addremove() Since we've changed to carry a similarity value by opts dict, it makes sense to leave a string '0'-'100' value unmodified.

bookmarks: switch from repo.changectx('.') to repo['.'] The two forms are synonymous and the new form is by far the more common form. Differential Revision: https://phab.mercurial-scm.org/D3033

stringutil: add function to pretty print an object This is inspired by the pprint() module/function (which we can't use because the output is different on Python 2 and 3 - namely the use of b'' literals). We hook it up to `hg debugwireproto` for printing the response to a wire protocol command. This foreshadows future peer work, which will support decoding CBOR responses into rich data structures.

wireproto: add frame flag to denote payloads as CBOR We may eventually want a separate frame type for this. But for now this is the easiest to implement. Differential Revision: https://phab.mercurial-scm.org/D2986
