Take advantage of those new handy _or_goto_error macros

Use them in various places where previously we either elided the error
checking (various lseek() calls) or used a combination of calls
(replaced by malloc_and_fill_or_goto_error()).

In the process, fix what is probably a bug (or else introduce one, but I
don't think so): audiodb_track_id_datum() computed the offset into the
timesTable wrongly, forgetting to multiply by 2.  (TODO: this should be
easily testable using the API).

Now all of LIBOBJS can be produced by my (Debian's) mingw32
cross-compiler, except for lshlib.o.
