Whatever you decide to use for the Unix implementation, *please* keep
dependencise on mime.types or file extensions out of the API, so that
other systems can implement different schemes. All you need for add and
import is one function for detecting the mime type, e.g.:

    svn_error_t *svn_mime_guess_type(const char **mime_type,
                                     const char *file_name,
                                     apr_pool_t *pool);

at the other end for checkout, update, and when the svn:mime-type
changes on an existing version-controlled file, you need something like:

    svn_error_t *svn_mime_assert_type(const char *mime_type,
                                      const char *file_name,
                                      apr_pool_t *pool);

That function would set any system-specific attrbutes on the file (e.g.,
on Risc OS) based on the mime_type parameter (we do something similar
today on Unix when the svn:executable property changes).
