Modified files:
        lib/libc/gen   : isctype.c ctype_.c 
        include        : ctype.h 

Log message:
Move ctype.h defines to the _CTYPE_ prefix, avoids clashes with identifiers in 
ports

Even if those _[BCNLPSUX] defines are in the reserved namespace, some
ports make use of those identifiers and thus need pointless
headscratching and patches.  Just use a longer reserved prefix.
We can't just #undef those defines as they are used in libc.

Change similar to what NetBSD did around 2010.  Went through base builds
and an amd64 bulk build, the only fallout was lib(e)stdc++ base_ctype.h.
"make includes" will install the latest ctype.h and libstdc++ ctype_base.h.
