[PATCH 04/27] Add copyright attribution for files in newlib/libc/ctype

[Keith Packard <keithp@keithp.com>]

These were extracted from git history, either by attributing to the
commit author or by finding license information added to other new
files in the same commit.

No licensing was added for those files for which none could be
inferred.

Signed-off-by: Keith Packard <keithp@keithp.com>
