Instead store all the strings in one continugous string (with internal \0) and use offsets to access the actual substrings. This replaces the pointers to the strings and therefore avoids relocations (and on x64, it actually shrinks TiffGeoTagNameType by reusing padding to store the offset field). This saves 720B of .data.rel.ro and 1080B of .rela.dyn (containing the relocation records) here while increasing .rodata by 384B. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
