Problem with r7950

r7950 says:

Introduce a convenient way to wrap errors from APR functions.

This introduces an infinite loop in the libsvn_subr/utf.c
functions convert_to_stringbuf and get_xlate_handle. Both these
functions call svn_error_wrap_apr. svn_error_wrap_apr then calls
svn_utf_cstring_to_utf8, which calls get_ntou_xlate_handle, which
calls get_xlate_handle. Round and round we go.

What to do about it though? Before r7950 svn_error_createf was
used here, which doesn't have the problem. But is that the right

Ben Collins-Sussman asks me for a reproduce recipe. I don't
actually have one, though the bug is quite obvious without it.
This was reported by a user of the pkgsrc package on NetBSD
-current. On that system, it is reproducible by not having
/usr/share/i18n. This results in ENOENT from apr_xlate_open, so
he suggested handling ENOENT with the other specially handled
errors. Unfortunately, that still leaves some error conditions
that lead to the infinite loop.
