Description:
------------
The svn library dies with an abort() (ie, you get an "Internal Server Error") on non-canonical pathnames.  This is an error which should be handled by treating all paths with svn_path_canonicalize before calling any svn function.

Affected functions are repos_create, svn_add, svn_checkout and probably more.

Reproduce code:
---------------
repos_create('/foo/bar/');

svn_add('/foo/./bar');

etc

Expected result:
----------------
No error, or at least a clean PHP error instead of hard abort on the C language level.

Actual result:
--------------
"Internal Server error", PHP aborts.
