delta-find: set the default candidate chunk size to 10

I ran performance and storage tests on repositories of various sizes and shapes
for the following values of the config : 5, 10, 20, 50, 100, no-chunking

The performance tests do not show any statistical impact on computation
times for large pushes and pulls.

For searching for an individual delta, this can provide a significant
performance improvement with a minor degradation of space-quality on the
result. (see data at the end of the commit).

For overall store size, the change :
- does not have any impact on many small repositories,
- has an observable, but very negligible impact on most larger repositories.
- One private repository we use for testing sees a small increase in size
  (1%) in the narrower version.
  We will try to get more numbers on a larger version of that repository to
  make sure nothing pathological happens.

We pick "10" as the limit as "5" seems a bit more risky.

There are room to improve the current code, by using more aggressive filtering
and better (i.e any) sorting of the candidates. However this is already a large
improvement for pathological cases, with little impact in the common
situations.

The initial motivation for this change is to fix performance of delta
computation for a file where the previous code ended up testing 20 000 possible
candidate-bases in one go, which is… slow. This affected about ½ of the file
revisions leading to atrocious performance, especially during some push/pull
operations.


Details about individual delta finding timing:
----------------------------------------------

The vast majority of benchmark cases are unchanged but the three below. The first
two do not see any impact on the final delta. The last one sees a change in
delta-size that is negligible compared to the full text size.

Pushing From an unlockable repo
--------------------------------
(issue3684)

Unability to lock the source repo should not prevent the push. It will prevent
the retrieval of remote phase during push. For example, pushing to a publishing
server won't turn changeset public.

1. Test that push is not prevented

  $ hg init Phi
  $ cd Upsilon
  $ chmod -R -w .hg
  $ hg push ../Phi
  pushing to ../Phi
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 14 changesets with 14 changes to 14 files (+3 heads)
  test-debug-phase: new rev 0:  x -> 0
  test-debug-phase: new rev 1:  x -> 0
  test-debug-phase: new rev 2:  x -> 0
  test-debug-phase: new rev 3:  x -> 0
  test-debug-phase: new rev 4:  x -> 0
  test-debug-phase: new rev 5:  x -> 0
  test-debug-phase: new rev 6:  x -> 0
  test-debug-phase: new rev 7:  x -> 0
  test-debug-phase: new rev 8:  x -> 0
  test-debug-phase: new rev 9:  x -> 0
  test-debug-phase: new rev 10:  x -> 0
  test-debug-phase: new rev 11:  x -> 0
  test-debug-phase: new rev 12:  x -> 0
  test-debug-phase: new rev 13:  x -> 0
  $ chmod -R +w .hg

2. Test that failed phases movement are reported

  $ hg phase --force --draft 3
  test-debug-phase: move rev 3: 0 -> 1
  test-debug-phase: move rev 7: 0 -> 1
  test-debug-phase: move rev 8: 0 -> 1
  test-debug-phase: move rev 9: 0 -> 1
  $ chmod -R -w .hg
  $ hg push ../Phi
  pushing to ../Phi
  searching for changes
  no changes found
  cannot lock source repo, skipping local public phase update
  [1]
  $ chmod -R +w .hg

3. Test that push is prevented if lock was already acquired (not a permission
error, but EEXIST)

  $ touch .hg/store/lock
  $ hg push ../Phi --config ui.timeout=1 --config ui.timeout.warn=0
  pushing to ../Phi
  waiting for lock on repository $TESTTMP/Upsilon held by ''
  abort: repository $TESTTMP/Upsilon: timed out waiting for lock held by ''
  (lock might be very busy)
  [20]
  $ rm .hg/store/lock

  $ cd ..

#endif

Test that clone behaves like pull and doesn't publish changesets as plain push
does.  The conditional output accounts for changes in the conditional block
above.

#if unix-permissions no-root
  $ hg -R Upsilon phase -q --force --draft 2
  test-debug-phase: move rev 2: 0 -> 1
#else
  $ hg -R Upsilon phase -q --force --draft 2

  test-debug-phase: move rev 3: 0 -> 1
  test-debug-phase: move rev 7: 0 -> 1
  test-debug-phase: move rev 8: 0 -> 1
  test-debug-phase: move rev 9: 0 -> 1
#endif
