- Change apply / prepare / ... as filter to use the field's value, which is now stored in fdata as well as cinfo. Now we don't have to reprocess the entire packet list when using these features. This also prevents the use of these features from overwriting custom column information. (custom columns can now be used in apply / prepare ... as filter) - Break col_expr and col_expr_val out into a struct that is included not only in cinfo, but now also fdata. - Have col_custom_set_fstr() quote FT_STRING & FT_STRINGZ when storing the col_expr_val value (for filter creation). svn path=/trunk/; revision=24511
