Once upon a time, larn 12.0 had functions named getchar() and putchar()

that conflicted with libc. We changed them to lgetchar() and xputchar()
respectively; larn 12.2 changed them to ttgetch() and ttputch(). After
reflecting on this for a while I've decided to adopt the larn 12.2
names; not so much for compatibility but for consistency going forward.
So, massrename them. Also make ttputch() static.
