Fixed compiler warnings

cmd-line-utils/readline/complete.c:
  Don't ignore value from fwrite()
cmd-line-utils/readline/terminal.c:
  Don't ignore value from fwrite()
extra/yassl/taocrypt/include/file.hpp:
  Changed prototype to be able to return value from fwrite()
extra/yassl/taocrypt/src/file.cpp:
  Return value from fwrite for put()
storage/xtradb/ut/ut0ut.c:
  Added casts to remove warnings for not critical usage of fwrite()
