use xfopen() in more places

xfopen()

- provides error details
- explains error on reading, or writing, or whatever operation
- has l10n support
- prints file name in the error

Some of these are missing in the places that are replaced with xfopen(),
which is a clear win. In some other places, it's just less code (not as
clearly a win as the previous case but still is).

The only slight regresssion is in remote-testsvn, where we don't report
the file class (marks files) in the error messages anymore. But since
this is a _test_ svn remote transport, I'm not too concerned.
