Merge from 5.1-build of the "my_bool for C" changeset.

Removing "#define bool BOOL" as it's dangerous.


include/config-win.h:
  This #define was confusing: a) it changes the semantics of bool but
  only on Windows (C++ standard says that casting int to bool to int
  yields 0 or 1, but if using BOOL (which is int) this breaks, see
  old BUG 11567 "Variable 'foreign_key_checks', and other variables,
  differs binlog tests") b) it is not needed in C++ which has a bool type
  c) it is not needed in C where we must use my_bool as bool either does
  not exist or changes size between C and C++.
