run-tests: allow some slack about 'waiting on lock' message

It is common to run the tests on very loaded machine when concurrent run might
take a bit longer. Such message are usually harmless, but anoying as they break
the tests.

Test that explicitly depends on this value have been adjusted. This make them
more robust anyway.

A fun case was `test-clone-pull-corruption.t` which, without the previous
changeset introducing extra flushing, ended use having a line 31 (`pulling from
../source`) changing order because the warning message was no longer flushing
stdin before using stderr (stderr being invisible in the test).

 # Modifying this script is tricky because it has many modes:
 #   - serial (default) vs parallel (-jN, N > 1)
 #   - no coverage (default) vs coverage (-c, -C, -s)
 #   - temp install (default) vs specific hg script (--with-hg, --local)
 #   - tests are a mix of shell scripts and Python scripts
 #
 # If you change this script, it is recommended that you ensure you
 # haven't broken it by running it in various modes with a representative
 # sample of test scripts.  For example:
 #
 #  1) serial, no coverage, temp install:
 #      ./run-tests.py test-s*
 #  2) serial, no coverage, local hg:
 #      ./run-tests.py --local test-s*
 #  3) serial, coverage, temp install:
 #      ./run-tests.py -c test-s*
 #  4) serial, coverage, local hg:
 #      ./run-tests.py -c --local test-s*      # unsupported
 #  5) parallel, no coverage, temp install:
 #      ./run-tests.py -j2 test-s*
 #  6) parallel, no coverage, local hg:
 #      ./run-tests.py -j2 --local test-s*
 #  7) parallel, coverage, temp install:
 #      ./run-tests.py -j2 -c test-s*          # currently broken
 #  8) parallel, coverage, local install:
 #      ./run-tests.py -j2 -c --local test-s*  # unsupported (and broken)
 #  9) parallel, custom tmp dir:
 #      ./run-tests.py -j2 --tmpdir /tmp/myhgtests
 #  10) parallel, pure, tests that call run-tests:
 #      ./run-tests.py --pure `grep -l run-tests.py *.t`
 #
 # (You could use any subset of the tests: test-s* happens to match
 # enough that it's worth doing parallel runs, few enough that it
 # completes fairly quickly, includes both shell and Python scripts, and
 # includes some scripts that run daemon processes.)

         testdir specifies the directory where tests are executed from. This

         jobs specifies the number of jobs to run concurrently. Each test
         executes on its own thread. Tests actually spawn new processes, so
         state mutation should not be an issue.

         whitelist and blacklist denote tests that have been whitelisted and

         Instead, whitelist and blacklist should be handled by the thing that
         populates the TestSuite with tests. They are present to preserve
         backwards compatible behavior which reports skipped tests as part
         of the results.
 
         keywords denotes key words that will be used to filter which tests
         to execute. This arguably belongs outside of TestSuite.

 Test that accessing to invalid changelog cache is avoided at
 subsequent operations even if repo object is reused even after failure
 of transaction (see 0a7610758c42 also)
 
 "hg log" after failure of transaction is needed to detect invalid
 cache in repoview: this can't detect by "hg verify" only.
 
 Combination of "finalization" and "empty-ness of changelog" (2 x 2 =
 4) are tested, because '00changelog.i' are differently changed in each
 cases.

 cache of repo.auditor should be discarded, so matcher would never traverse

 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
+  $ 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 7: 0 -> 1
   test-debug-phase: move rev 8: 0 -> 1
   test-debug-phase: move rev 9: 0 -> 1
