tests: partially fix test-transaction-rollback-on-revlog-split.t on Windows For whatever reason, the extra space causes different output on Windows: $ printf '% 20d' '1' | xxd - 0000000: 2020 2020 2020 2020 2020 2020 2020 2020 0000010: 2020 2020 31 1 vs WSL: /mnt/c/Users/Matt/hg/tests$ printf '% 20d' '1' | xxd - 00000000: 2020 2020 2020 2020 2020 2020 2020 2020 00000010: 2020 2031 Without the space, they both agree the last word is 2031. There are other failures on Windows that I don't understand that are introduced by 46b828b85eb7 and 18415fc918a1. Differential Revision: https://phab.mercurial-scm.org/D10763

tests: fix test-transaction-safety.t on Windows Mostly this is about `C:\dir\sub` style paths being turned into `C:dirsub` by MSYS, and not being about to execute shell scripts in hooks directly. See also a12819559ccb::9e3979a25bfe. Differential Revision: https://phab.mercurial-scm.org/D10762

docket: move the uid logic in the `revlogutils.docket` module We want to use it for revlog-v2 (& Co), it seems more logical to have the logic lives inside the `docket` file than the `nodemap` file. Differential Revision: https://phab.mercurial-scm.org/D10755

persistent-nodemap: use the intended uuid size I overlooked this in the initial implementation. The format already supporting any uuid size so, nothing horrible should happens. Differential Revision: https://phab.mercurial-scm.org/D10754

persistent-nodemap: add a way to make the picked uid predictable This will make the test less volatile and therefore easier to maintain. I am setting this is for the persistent nodemap docket first, but my target is to use similar logic for the revlogv2 (and co) test. For persisent nodemap, they are too many different in how each test variants (with rust, without rust, etc) needs new uid for this be really useful (right now). However it will be directly useful for the revlogv2 logic. Differential Revision: https://phab.mercurial-scm.org/D10753
