transaction: support cache file in backupentries

We do not want to abort if anything wrong happen while handling a cache file.
Cache file have way to be invalidated and if old/bad version stay no
misbehavior will happen. Proper value will eventually be computed and the wrong
will be righten.

This changeset use the transaction reporter (usually writing on stderr) to write
details about failed cache handling. This will only apply to write operation
using a transaction. The usual update during read only operation will stay a
debug message.

I was on the way to bring these message back to debug level when I realised it
could be a feature. People with write access to the repository are likely to
have the power to fix error related to cache (and it is valuable to fix them).
So let the things as is for now.

  update the current patch
  
      If any file patterns are provided, the refreshed patch will contain only
      the modifications that match those patterns; the remaining modifications
      will remain in the working directory.
  
      If -s/--short is specified, files currently included in the patch will be
      refreshed just like matched files and remain in the patch.
  
      If -e/--edit is specified, Mercurial will start your configured editor for
      you to enter a message. In case qrefresh fails, you will find a backup of
      your message in ".hg/last-message.txt".
  
      hg add/remove/copy/rename work as usual, though you might want to use git-
      style patches (-g/--git or [diff] git=1) to track copies and renames. See
      the diffs help topic for more information on the git diff format.
