[PATCH] Multiple WC copies/moves without intervening ci

This patch allows multiple moves/copies of a file/directory in the WC with
no intervening commit. It is based on a patch originally developed by
Ivan Zhakov and was most recently discussed in these threads:

I factored out the copyfrom* functionality in the latest patch below.
 
I also added two more tests: move_file_back_and_forth and
move_dir_back_and_forth. These two tests move a file(dir) to a new
location, moves it back to the original location, then commits it. The
patch as it stands now permits this for files, treating the double move as
a replacement. It doesn't allow it for directories as the current code in
svn_wc_copy2() prohibits this and returns a SVN_ERR_WC_INVALID_SCHEDULE
error ("Cannot copy to dir as it is scheduled for deletion"). What do
folks think should happen in these cases?

Any other thoughts, comments, criticisms, rants, lavish praise, diatribes,
etc. appreciated.
