Consolidate bool type

'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.

All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.

Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.
