tools: include necessary headers explicitly
Several host-tools use "bool" type without including <stdbool.h>.
This relies on the crappy header inclusion chain.
tools/Makefile has the following line:
HOST_EXTRACFLAGS += -include $(srctree)/include/libfdt_env.h \
All host-tools are forced to include libfdt_env.h even if they are
totally unrelated to FDT. Then, <stdbool.h> is indirectly included
as follows:
include/libfdt_env.h
-> include/linux/types.h
-> <stdbool.h>
I am fixing this horrible crap. In advance, I need to add necessary
include directives explicitly. tools/fdtgrep.c needs more; <fctl.h>
for open() and <errno.h> for errno.
