This refactor simplifies and streamlines the code associated with server side filters. Apart from immediate benefits (clearer code, less duplication) it is also hoped that this will make it easier to add write filters. The data pointer dbfl_ref.field can now either point to a copy owned by a filter, or it can point to the original data owned by a record. In the latter case, the dbfl_ref.dtor is NULL. The dbExtractArray* functions are unified to the single function dbExtractArray and stripped of conversion functionality. This is redundant because we always call dbGet after applying filters, which takes care of conversion. Accordingly, dbChannelMakeArrayCopy is now obsolete and its single use (in the ts filter) replaced with dbExtractArray. Instead, we add the helper function dbChannelGetArrayInfo to wrap the common boilerplate around calls to the get_array_info method, used in both arr.c and ts.c.
