shelve: store shelved node in a new data file
It is useful for a version of shelve not based on bundle and strip. Having
more data does not hurt the bundle based case so we introduce it in all cases
before doing more rework.
We also keep storing the patch using another method.
note: We could have this metadata file list all the file involved in the
shelve and use that for cleanup. This would be more future proof than having a
hard-coded list of file to purge. However, this is an adventure for another
series.

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";

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

commandfinish

logtoprocess commandfinish output:
logtoprocess foo output:

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)
