revlog-compression: update the config to be a list
format.revlog-compression is now a list of engine, the first supported one is to
be used. Doing this have several benefits:
1) this is fully backward compatible, config using a single entry will be read
as a single item list, not changing any behavior.
2) This open the way to use zstd by default without impacting platform were it
is not available. This will be done in a later changesets.
Using zstd provide a significant performance boost explained in : bb271ec2fbfb.
However zstd is not available in some cases, A notable example is the `--pure`
version of Mercurial which doesn't come with zstd support.

== New Features == * New config `commands.commit.post-status` shows status after successful commit. * `hg root` now has templating support, including support for showing where a repo share's source is. See `hg help -v root` for details. * New `--force-close-branch` flag for `hg commit` to forcibly close branch from a non-head changeset. * The curses-based interface for commands like `hg commit -i` now supports a range-select mechanism. Select the first line using space like before, navigate to the last line, and press X (capital x) to set all items in the range at once. Lowercase x has been added as a synonym for space to help reinforce the mechanism, and pressing enter/return continues to be a synonym for "toggle the current line and move down to the next item in this section." == New Experimental Features == * New config `experimental.log.topo` makes `hg log -G` use topological sorting. This is especially useful for aliases since it lets the alias accept an `-r` option while still using topological sorting with or without the `-r` (unlike if you use the `sort(..., topo)` revset). == Bug Fixes == * issue4292: "hg log and {files} {file_adds} {file_mods} {file_dels} in template show wrong files on merged revision". See details in "Backwards Compatibility Changes". == Backwards Compatibility Changes == * Removed (experimental) support for log graph lines mixing parent/grandparent styles. Setting e.g. `experimental.graphstyle.parent = !` and `experimental.graphstyle.grandparent = 3.` would use `!` for the first three lines of the graph and then `.`. This is no longer supported. * If `ui.origbackuppath` had been (incorrectly) configured to point to a file, we will now replace that file by a directory and put backups in that directory. This is similar to how we would previously replace files *in* the configured directory by subdirectories. * Template keyword `{file_mods}`, `{file_adds}`, and `{file_dels}` have changed behavior on merge commits. They used to be relative to the first parent, but they now consider both parents. `{file_adds}` shows files that exists in the commit but did not exist in either parent. `{file_dels}` shows files that do not exist in the commit but existed in either parent. `{file_mods}` show the remaining files from `{files}` that were not in the other two sets. == Internal API Changes == * Matchers are no longer iterable. Use `match.files()` instead. * `match.visitdir()` and `match.visitchildrenset()` now expect the empty string instead of '.' to indicate the root directory. * `util.dirs()` and `util.finddirs()` now include an entry for the root directory (empty string). * shelve is no longer an extension now. it will be turned on by default. * New API to manage unfinished operations: Earlier there were distinct APIs which dealt with unfinished states and separate lists maintaining them that are `cmdutil.afterresolvestates`, `cmdutil.unfinishedstates` and `cmdutil.STATES`. Now these have been unified to a single API which handles the various states and their utilities. This API has been added to `state.py`. Now instead of adding to these 3 lists independently a state for a new operation can be registered using `addunfinished()` in `state` module. * `cmdutil.checkunfinished()` now includes detection for merge too. * merge abort has been disallowed in case an operation of higher precedence is in progress to avoid cases of partial abort of operations. * We used to automatically attempt to make extensions compatible with Python 3 (by translating their source code while loading it). We no longer do that.
