vcs-svn: Combine repo_replace and repo_modify functions

Browse Source 
There are two functions to change the staged content for a path in the
svn importer's active commit: repo_replace, which changes the text and
returns the mode, and repo_modify, which changes the text and mode and
returns nothing.

Worse, there are more subtle differences:

 - A mark of 0 passed to repo_modify means "use the existing content".
   repo_replace uses it as mark :0 and produces a corrupt stream.

 - When passed a path that is not part of the active commit,
   repo_replace returns without doing anything.  repo_modify
   transparently adds a new directory entry.

Get rid of both and introduce a new function with the best features of
both: repo_modify_path modifies the mode, content, or both for a path,
depending on which arguments are zero.  If no such dirent already
exists, it does nothing and reports the error by returning 0.
Otherwise, the return value is the resulting mode.
