ha_innobase.cc, ut0ut.c, univ.i, ut0ut.h:

  Redefine sprintf as ut_sprintf inside InnoDB code; some old Unixes may have a pointer as the return type of sprintf
lock0lock.c:
  Add safety against buffer overruns in latest deadlock info
srv0srv.c:
  Add safety against buffer overruns in SHOW INNODB STATUS
os0thread.h, os0thread.c:
  Fix a portability bug introduced in Windows when we changed os_thread_id_t to be the same as os_thread_t
