  [GOFF] Write out relocations in the GOFF writer

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.
