add ctype.h header

Sometimes coreboot needs to compile external code (e.g.
vboot_reference) using its own set of system header files.  When
these headers don't line up with C Standard Library, it causes
problems.

Create ctype.h header file.  Relocate ctype.h functions from
string.h into ctype.h.  Update source files which call ctype.h
functions accordingly.

Note that ctype.h still lacks five functions which are not used
in coreboot source:
  isalnum, isalpha, iscntrl, isgraph, ispunct
