commands: use dirstateguard instead of begin/end-parentchange for backout

Before this patch, "hg backout" uses 'begin'/'end'-'parentchange()'
of 'dirstate' class to avoid writing incomplete dirstate changes out
at failure.

But this framework doesn't work as expected, if 'dirstate.write()' is
invoked between them. In fact, in-memory dirstate changes may be
written out at 'repo.status()' implied by 'merge.update()', even
before this patch.

To restore dirstate as expected at failure of "hg backout", this patch
uses 'dirstateguard' instead of 'begin'/'end'-'parentchange()'.

This tests if hgweb and hgwebdir still work if the REQUEST_URI variable is
no longer passed with the request. Instead, SCRIPT_NAME and PATH_INFO
should be used from d74fc8dec2b4 onward to route the request.
