Add support for writing relocations. Since the symbol numbering is only available after the symbols are written, the relocations are collected in a vector. At write time, the relocations are converted using the symbols ids, compressed and written out. A relocation data record is limited to 32K-1 bytes, which requires making sure that larger relocation data is written into multiple records.
