narrow: only send the narrowspecs back if ACL in play

I am unable to think why we need to send narrowspecs back from the server. The
current state adds a 'narrow:spec' part to each changegroup which is generated
when narrow extension is enabled. So we are sending narrowspecs on pull also.

There is a problem with sending the narrowspecs the way we are doing it right
now. We add include and exclude as parameter of the 'narrow:spec' bundle2 part.
The the len of include or exclude string increase 255 which is obvious while
working on large repos, bundle2 generation code breaks. For more on that refer
issue5952 on bugzilla.

I was thinking why we need to send the narrowspecs back, and deleted the
'narrow:spec' bundle2 part generation code and found that only narrow-acl test
has some failure.

With this patch, we will only send the 'narrow:spec' bundle2 part if ACL is
enabled because the original narrowspecs in those cases can be a subset of
narrowspecs user requested.

There are phase related output change in couple of tests. The output change
shows that we are now dealing in public phases completely. So maybe sending the
narrow:spec bundle2 part was preventing phases being exchanged or phase bundle2
data being applied.

ATTENTION: logtoprocess runs commands asynchronously. Be sure to append "| cat"
to hg commands, to wait for the output, if you want to test its output.
Otherwise the test will be flaky.

Test if logtoprocess correctly captures command-related log calls.

  $ hg init
  $ cat > $TESTTMP/foocommand.py << EOF
  > from __future__ import absolute_import
  > from mercurial import registrar
  > cmdtable = {}
  > command = registrar.command(cmdtable)
  > configtable = {}
  > configitem = registrar.configitem(configtable)
  > configitem('logtoprocess', 'foo',
  >     default=None,
  > )
  > @command(b'foo', [])
  > def foo(ui, repo):
  >     ui.log('foo', 'a message: %(bar)s\n', bar='spam')
  > EOF
  $ cp $HGRCPATH $HGRCPATH.bak
  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > logtoprocess=
  > foocommand=$TESTTMP/foocommand.py
  > [logtoprocess]
  > command=(echo 'logtoprocess command output:';
  >     echo "\$EVENT";
  >     echo "\$MSG1";
  >     echo "\$MSG2") > $TESTTMP/command.log
  > commandfinish=(echo 'logtoprocess commandfinish output:';
  >     echo "\$EVENT";
  >     echo "\$MSG1";
  >     echo "\$MSG2";
  >     echo "\$MSG3") > $TESTTMP/commandfinish.log
  > foo=(echo 'logtoprocess foo output:';
  >     echo "\$EVENT";
  >     echo "\$MSG1";
  >     echo "\$OPT_BAR") > $TESTTMP/foo.log
  > EOF

Running a command triggers both a ui.log('command') and a
ui.log('commandfinish') call. The foo command also uses ui.log.

Use sort to avoid ordering issues between the various processes we spawn:
  $ hg foo
  $ sleep 0.2
  $ cat $TESTTMP/command.log | sort
  
  command
  foo
  foo
  logtoprocess command output:

#if no-chg
  $ cat $TESTTMP/commandfinish.log | sort
  
  0
  commandfinish
  foo
  foo exited 0 after * seconds (glob)
  logtoprocess commandfinish output:
  $ cat $TESTTMP/foo.log | sort
  
  a message: spam
  foo
  logtoprocess foo output:
  spam
#endif

Confirm that logging blocked time catches stdio properly:
  $ cp $HGRCPATH.bak $HGRCPATH
  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > logtoprocess=
  > pager=
  > [logtoprocess]
  > uiblocked=echo "\$EVENT stdio \$OPT_STDIO_BLOCKED ms command \$OPT_COMMAND_DURATION ms" > $TESTTMP/uiblocked.log
  > [ui]
  > logblockedtimes=True
  > EOF

  $ hg log
  $ sleep 0.2
  $ cat $TESTTMP/uiblocked.log
  uiblocked stdio [0-9]+.[0-9]* ms command [0-9]+.[0-9]* ms (re)

Try to confirm that pager wait on logtoprocess:

Add a script that wait on a file to appears for 5 seconds, if it sees it touch
another file or die after 5 seconds. If the scripts is awaited by hg, the
script will die after the timeout before we could touch the file and the
resulting file will not exists. If not, we will touch the file and see it.

  > for i in \`$TESTDIR/seq.py 50\`; do

  >   else
  >     sleep 0.1;
  >   fi

  $ chmod +x $TESTTMP/wait-output.sh
