store: issue a single entry for each revlog

We now yield a single entry, with data about each files involved. This help to
simplify multiple code using this and it will help to further simplify and
fixes the streaming code.

== Default Format Change ==

These changes affect newly created repositories (or new clones) done with
Mercurial 6.3.

== New Experimental Features ==

== Bug Fixes ==

 * shelve: demonstrate that the state is different across platforms (issue6735)
 * shelve: in test for trailing whitespace, strip commit (issue6735)
 * shelve: remove strip and rely on prior state (issue6735)
 * tests: fix http-bad-server expected errors for python 3.10 (issue6643)
 * status: let `--no-copies` override `ui.statuscopies`
 * releasenotes: use re.MULTILINE mode when checking admonitions
 * rhg: fallback to slow path on invalid patterns in hgignore
 * Fix a bunch of leftover str/bytes issues from Python 3 migration
 * keepalive: ensure `close_all()` actually closes all cached connections
 * lfs: fix blob corruption when tranferring with workers on posix
 * lfs: avoid closing connections when the worker doesn't fork
 * dirstate-v2: update constant that wasn't kept in sync
 * dirstate-v2: fix edge case where entries aren't sorted
 * upgrade: no longer keep all revlogs in memory at any point

== Backwards Compatibility Changes ==

 * chg worker processes will now correctly load per-repository configuration
   when given a both a relative `--repository` path and an alternate working
   directory via `--cwd`. A side-effect of this change is that these workers
   will now return an error if hg cannot find the current working directory,
   even when a different directory is specified via `--cwd`.
 * phase: rename the requirement for internal-phase from `internal-phase` to `use-internal-phase` (see 74fb1842f8b962cf03d7cd5b841dbcf2ae065587)
