buildrpm: fix embarassing bug in shell variable expansions `$distance_$node` looks up and concatenates `$distance_` and `$node`. `$distance_` is empty, so we were getting the node without the distance. Using the curly braces makes our intent explicit and produces better-versioned RPMS. Differential Revision: https://phab.mercurial-scm.org/D4493

absorb: clarify the reason for not finding changesets to modify I'm used to pushing to non-publishing repos, so this was the last thing I thought to check.

merge with stable Includes an extra bump of the version number for parsers because the merge produces a new, distinct version of the code.

state: use our CBOR module This was the last consumer of the vendored CBOR package in core. Differential Revision: https://phab.mercurial-scm.org/D4471

wireprotov2peer: use our CBOR decoder Behavior should be the same in order to preserve backwards compatibility. We obviously want to stream values in this code. We'll do that in subsequent commits. Differential Revision: https://phab.mercurial-scm.org/D4470

debugcommands: use our CBOR decoder It implements the set of CBOR needed for the wire protocol. Differential Revision: https://phab.mercurial-scm.org/D4469

wireprotov2server: use our CBOR encoder Again, test output changed slightly because of map key ordering differences. This shouldn't matter. I could have called oncommandresponsereadygen() with the raw output from the stream encoder. However, this changed test output further. I left a TODO to follow up on that later.

wireprotoserver: use our CBOR encoder Moving away from the vendored package. Again, our encoder normalizes keys differently from the vendored package (for now), hence the test changes. Differential Revision: https://phab.mercurial-scm.org/D4467

wireprotoframing: use our CBOR module Tests changed because our CBOR encoder appears to sort map keys differently from the vendored CBOR package. The CBOR specification does define canonical sorting rules for keys based on the byte values. I'm guessing our implementation doesn't follow them. But our encoder doesn't guarantee that it conforms with the canonical specification. Right now, we just care that output is deterministic. And our encoder does guarantee that.

httppeer: use our CBOR decoder We just implemented our own CBOR decoder. Let's use it in httppeer. Differential Revision: https://phab.mercurial-scm.org/D4465
