obsolescence: add test case D-3 for obsolescence markers exchange

About 3 years ago, in August 2014, the logic to select what markers to select on
push was ported from the evolve extension to Mercurial core. However, for some
unclear reasons, the tests for that logic were not ported alongside.
I realised it a couple of weeks ago while working on another push related issue.
I've made a clean up pass on the tests and they are now ready to integrate the
core test suite. This series of changesets do not change any logic. I just adds
test for logic that has been around for about 10 versions of Mercurial.

They are a patch for each test case. It makes it easier to review and postpone
one with documentation issues without rejecting the wholes series.

This patch introduce case D3: missing prune target (prune not in "pushed set")

Each test case comes it in own test file. It help parallelism and does not
introduce a significant overhead from having a single unified giant test file.
Here are timing  to support this claim.

test --time

  $ hg --time help -q help 2>&1 | grep time > /dev/null
  $ hg init a
  $ cd a

#if lsprof

test --profile

  $ prof='hg --config profiling.type=ls --profile'

  $ $prof st 2>../out
  $ grep CallCount ../out > /dev/null || cat ../out

  $ $prof --config profiling.output=../out st
  $ grep CallCount ../out > /dev/null || cat ../out

  $ $prof --config profiling.output=blackbox --config extensions.blackbox= st
  $ grep CallCount .hg/blackbox.log > /dev/null || cat .hg/blackbox.log

  $ $prof --config profiling.format=text st 2>../out
  $ grep CallCount ../out > /dev/null || cat ../out

  $ echo "[profiling]" >> $HGRCPATH
  $ echo "format=kcachegrind" >> $HGRCPATH

  $ $prof st 2>../out
  $ grep 'events: Ticks' ../out > /dev/null || cat ../out

  $ $prof --config profiling.output=../out st
  $ grep 'events: Ticks' ../out > /dev/null || cat ../out

#endif

#if lsprof serve

Profiling of HTTP requests works

  $ $prof --config profiling.format=text --config profiling.output=../profile.log serve -d -p $HGPORT --pid-file ../hg.pid -A ../access.log
  $ cat ../hg.pid >> $DAEMON_PIDS
  $ hg -q clone -U http://localhost:$HGPORT ../clone

A single profile is logged because file logging doesn't append
  $ grep CallCount ../profile.log | wc -l
  \s*1 (re)

#endif

Install an extension that can sleep and guarantee a profiler has time to run

  $ cat >> sleepext.py << EOF
  > import time
  > from mercurial import cmdutil, commands
  > cmdtable = {}
  > command = cmdutil.command(cmdtable)
  > @command('sleep', [], 'hg sleep')
  > def sleep(ui, *args, **kwargs):
  >     time.sleep(0.1)
  > EOF

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > sleep = `pwd`/sleepext.py
  > EOF

statistical profiler works

  $ hg --profile sleep 2>../out
  $ grep Sample ../out
  Sample count: \d+ (re)

Various statprof formatters work

  $ hg --profile --config profiling.statformat=byline sleep 2>../out
  $ head -n 1 ../out
    %   cumulative      self          
  $ grep Sample ../out
  Sample count: \d+ (re)

  $ hg --profile --config profiling.statformat=bymethod sleep 2>../out
  $ head -n 1 ../out
    %   cumulative      self          
  $ grep Sample ../out
  Sample count: \d+ (re)

  $ hg --profile --config profiling.statformat=hotpath sleep 2>../out
  $ grep Sample ../out
  Sample count: \d+ (re)

  $ hg --profile --config profiling.statformat=json sleep 2>../out
  $ cat ../out
  \[\[\d+.* (re)

statprof can be used as a standalone module

  $ $PYTHON -m mercurial.statprof hotpath
  must specify --file to load

  $ cd ..
