[PATCH] issue 1954 - v6

Hello,

Sorry about the delay in getting back. Philip's email made me go back
and verify a lot of unwritten notes. This is my current understanding of
the issue and code flow, please feel free to pound on it :):

* the issue is to check for validity of svn pathnames provided to the
add and import commands. Putting the check in svn_wc_add covers add,
copy, and move (and merge, according to Philip, though I haven't
verified this).

* Valid svn pathnames are UTF-8 sequences that do not contain control
characters. This does not address the issue of encoded control
characters in URIs.

- Putting the check in libsvn_wc:adm_opts.c:svn_wc_add() covers
svn_client_add(), svn_client_copy(), and svn_client_move2().

- libsvn_client:commit.c:import_file() and import_dir() are used to
cover svn_client_import() since they don't call functions in libsvn_wc.

The updated patch is attached. (libsvn_wc/{copy.c, update_editor.c} and
libsvn_client/add.c) have been removed.

Regards
Sameer
