compression: introduce a `storage.revlog.zstd.level` configuration

This option control the zstd compression level used when compressing revlog
chunk. The usage of zstd for revlog compression has not graduated from
experimental yet, but we intend to fix that soon.

The option name for the compression level is more straight forward to pick, so
this changesets comes first.  Having a dedicated option for each compression
engine is useful because they don't support the same range of values.

I ran the same measurement as for the zlib compression level (in the parent
changesets). The variation in repository size is stay mostly in the same (small)
range. The "read/write" performance see smallish variation, but are overall much
better than zlib. Write performance show the same tend of having better write
performance for when reaching high-end compression.

Again, we don't intend to change the default zstd compression level (currently:
3) in this series. However this is worth investigating in the future.

The Performance comparison of zlib vs zstd is quite impressive. The repository
size stay in the same range, but the performance are much better in all
situations.

Comparison summary
==================

We are looking at:
- performance range for zlib
- performance range for zstd
- comparison of default zstd (level-3) to default zlib (level 6)
- comparison of the slowest zstd time to the fastest zlib time

  update: 4 new changesets (update)

Sharing a local repo with missing local subrepos (i.e. it was never updated
from null) works because the default path is copied from the source repo,
whereas clone should fail.

  $ hg --config progress.disable=True clone -U ../empty ../empty2

  $ hg --config extensions.share= --config progress.disable=True \

Test archiving when there is a directory in the way for a subrepo
created by archive:

  cloning subrepo foo from $TESTTMP/empty/foo

  $ cd ..
  $ hg clone repo repo2

  cloning subrepo foo from $TESTTMP/repo/foo
  cloning subrepo foo/bar from $TESTTMP/repo/foo/bar
