stream-clone: avoid opening a revlog in case we do not need it

Opening an revlog has a cost, especially if it is inline as we have to scan the
file and construct an index.

To prevent the associated slowdown, we just do a minimal scan to check that an
inline file is still inline, and simply stream the file without creating a
revlog when we can.

This provides a big boost compared to the previous changeset, even if the full
generation is still penalized by the initial gathering of information.

All benchmarks are run on linux with Python 3.10.7.
# benchmark.name             = hg.exchange.stream.generate
# benchmark.variants.version = v2

### Compared to the previous changesets

We get a large win all across the board!

### Compared to 6.4.3

We are still significantly slower than 6.4.3, the extra time is usually twice
slower than the extra time we observe on the locked section, which is a quite
interesting information.

Except for mercurial-central that is much faster. That discrepancy is not really
explained yet.

Multiple copy sources of a file:

  $ echo 0 >> a

 since file 'a' has multiple copy sources at the revision 4, ancestors can't
 be indexed solely by fctx.linkrev().

  $ hg log -T '{rev}: {desc}\n' -f a
  10: (a0,b1->a1)->a

Test that log should respect the order of -rREV even if multiple OR conditions
are specified (issue5100):

  $ hg init revorder

  $ echo 0 >> f0
  $ hg ci -qAm k0 -u u0
  $ hg branch -q b1
  $ echo 1 >> f1
  $ hg ci -qAm k1 -u u1
  $ hg branch -q b2
  $ echo 2 >> f2
  $ hg ci -qAm k2 -u u2

  $ hg update -q b2
  $ echo 3 >> f2
  $ hg ci -qAm k2 -u u2
  $ hg update -q b1
  $ echo 4 >> f1
  $ hg ci -qAm k1 -u u1
  $ hg update -q b0
  $ echo 5 >> f0
  $ hg ci -qAm k0 -u u0

Issue2383: hg log showing _less_ differences than hg diff

  $ hg init issue2383
  $ cd issue2383

Create a test repo:

  $ echo a > a
  $ hg ci -Am0
  adding a
  $ echo b > b
  $ hg ci -Am1
  adding b
  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo b > a
  $ hg ci -m2
  created new head

Merge:

  $ hg merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)

Make sure there's a file listed in the merge to trigger the bug:

  $ echo c > a
  $ hg ci -m3

New namespace is registered per repo instance, but the template keyword
is global. So we shouldn't expect the namespace always exists. Using
ssh:// makes sure a bundle repository is created from scratch. (issue6301)
