lfs: ensure the blob is linked to the remote store on skipped uploads I noticed a "missing" blob when pushing two repositories with common blobs to a fresh server, and then running `hg verify` as a user different from the one running the web server. When pushing the second repo, several of the blobs already existed in the user cache, so the server indicated to the client that it doesn't need to upload the blobs. That's good enough for the web server process to serve up in the future. But a different user has a different cache by default, so verify complains that `lfs.url` needs to be set, because it wants to fetch the missing blobs. Aside from that corner case, it's better to keep all of the blobs in the repo whenever possible. Especially since the largefiles wiki says the user cache can be deleted at any time to reclaim disk space- users switching over may have the same expectations.

cbor: teach the encoder to handle python `long` type for Windows The tests for 2**32 and -7000000000 were blowing up, complaining about not knowing how to encode type 'long'. sys.maxint tops out at 2**31-1 on Windows, but I guess is 2^63-1 on Linux? I *think* we're OK on the decode side, as there is an assertion that the decoded value is equal to the original primitive value. I opted for the pycompat alias instead of swallowing the NameError because the vendored cbor package uses an alias, and I see at least pywatchman and templatefilters open codes their own aliases.

buildrpm: remove TODO that looks done to me Differential Revision: https://phab.mercurial-scm.org/D4494

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.
