Remove unneeded #include statements completely
Unistd.h was only used to get a definition of NULL in all files. Add our
own NULL #define and remove unistd.h from flash.h
stdio.h has no place in flash.h, it should be included only in files
which really need it.
Add #include statements in individual .c files where needed.
Replace a few printf with msg_* to eliminate the need for stdio.h.
Corresponding to flashrom svn r1021.
