Ensure that a small system BUFSIZ does not affect parser guessing

raptor_internal.h: Ensure that RAPTOR_READ_BUFFER_SIZE is never smaller than 4096. (It really only needs to be as large as FIRSTN in raptor_parse.c, i.e. 1024, but 4kB isn't all that much nowadays anyway)

(raptor_world_guess_parser_name): Added a compile-time check to ensure that RAPTOR_READ_BUFFER_SIZE is at least as large as FIRSTN, because otherwise the guesser sees fewer than FIRSTN bytes from the document.
Fix DLL export linkage for internal functions needed by the test programs

This allows the test programs to be linked against a DLL build of Raptor.
