Description:
This bug is reported per request from Magnus Svensson and relates to BUG#24566.

We need to make sure that we properly use offset type in the server code to avoid bugs like BUG#24566.

How to repeat:
At least relay logs and CSV engine seem to be affected, check rpl_rli.cc and ha_tina.cc/ha_tina.h.

Suggested fix:
We likely shouldn't use off_t at all. For mysys functions like my_seek/my_pread/my_pwrite we should use my_off_t instead. For low-level functions like lseek/pread/pwrite we should use os_off_t.
