Export/import/common label size is increased from 33 to 64. Fixed the bug
that caused wrong behavior of rdfgetheaderrec() if label length was 32.
Changed error codes from numeric values to symbolic constants.
Moved some routines from rdfdump.c to rdoff.c. They will be utilized also
by rdfdisasm, which is being developed.
- Panos Minos's LDRDF fix (correct export of relocation records);
- Panos Minos's symtab.c verbose dump fix;
- Librarian (rdflib) now puts a signature block when creating a library
(instead of creating an empty file). In theory it doesn't break binary
compatibility, but due to a bug in the original 'rdlib.c' you can't
use old LDRDF with new libraries. Fix this bug as well.
- Other minor changes in LDRDF.
