subrepo: avoids empty commit when .hgsubstate is dirty (issue2403)

This patch avoids empty commit when .hgsubstate is dirty. Empty commit
was caused by .hgsubstate being updated back to the state of the
working copy parent when committing, if a user had changed it manually
and not made any changes in subrepositories.

The subrepository state from the working copies parent is compared
with the state calculated as a result of trying to commit the
subrepositories. If the two states are the same, then return None
otherwise the commit is just done.

The line: "committing subrepository x" will be written if there is
nothing committed, but .hgsubstate is dirty for x subrepository.

  output the current or given revision of files
  
      Print the specified files as they were at the given revision. If no
      revision is given, the parent of the working directory is used, or tip if
      no revision is checked out.
  
      Output may be to a file, in which case the name of the file is given using
      a format string. The formatting rules are the same as for the export
      command, with the following additions:
  
      "%s"  basename of file being printed
      "%d"  dirname of file being printed, or '.' if in repository root
      "%p"  root-relative path name of file being printed
  
      Returns 0 on success.
  
  options:
  
   -o --output FORMAT        print output to file with formatted name
   -r --rev REV              print the given revision
      --decode               apply any matching decode filter
   -I --include PATTERN [+]  include names matching the given patterns
   -X --exclude PATTERN [+]  exclude names matching the given patterns
  
  [+] marked option can be specified multiple times
