contrib: fix check-commit to not reject commits from `hg sign` and `hg tag` I'm tired of having a spurious red build every time we do a release. Fix it once and for all.

Added signature for changeset a1dd2c0c479e

Added tag 4.1-rc for changeset a1dd2c0c479e

tests: fix up some http tests for no-zstd case

freeze: merge default into stable for 4.1 code freeze

patchbomb: add tmpdir parameter to ui.edit call

histedit: add tmpdir parameter to ui.edit call

cmdutil: add tmpdir parament to ui.edit calls

ui: add a parameter to set the temporary directory for edit Until callsites are updated, this will have no effect. Once callsites are updated, specifying experimental.editortmpinhg will create editor temporary files in a subdirectory of .hg, which will make it easier for tool integrations to determine what repository is in play when they're asked to edit an hg-related file.

help: update help for `hg update` which was misleading (issue5427)
