lfs: add note messages indicating what store holds the lfs blob

The following corruption related patches were written prior to adding the user
level cache, and it took awhile to track down why the tests changed.  (It
generally made things more resilient.)  But I think this will be useful to the
end user as well.  I didn't make it --debug level, because there can be a ton of
info coming out of clone/push/pull --debug.  The pointers are sorted for test
stability.

I opted for ui.note() instead of checking ui.verbose and then using ui.write()
for convenience, but I see most of this extension does the latter.  I have no
idea what the preferred form is.

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"
  > commandfinish=echo 'logtoprocess commandfinish output:';
  >     echo "\$EVENT";
  >     echo "\$MSG1";
  >     echo "\$MSG2";
  >     echo "\$MSG3"
  > foo=echo 'logtoprocess foo output:';
  >     echo "\$EVENT";
  >     echo "\$MSG1";
  >     echo "\$OPT_BAR"
  > 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 | cat | sort
  
  
  
   (chg !)
  0
  a message: spam
  command
  command (chg !)
  commandfinish
  foo
  foo
  foo
  foo
  foo exited 0 after * seconds (glob)
  logtoprocess command output:
  logtoprocess command output: (chg !)
  logtoprocess commandfinish output:
  logtoprocess foo output:
  serve --cmdserver chgunix * (glob) (chg !)
  serve --cmdserver chgunix * (glob) (chg !)
  spam

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"
  > [ui]
  > logblockedtimes=True
  > EOF

  $ hg log | cat
  uiblocked stdio [0-9]+.[0-9]* ms command [0-9]+.[0-9]* ms (re)
