refactor get_textconv to not require diff_filespec
This function actually does two things: 1. Load the userdiff driver for the filespec. 2. Decide whether the driver has a textconv component, and initialize the textconv cache if applicable. Only part (1) requires the filespec object, and some callers may not have a filespec at all. So let's split them it into two functions, and put part (2) with the userdiff code, which is a better fit.
