Subject: [PATCH] sh/name.c: rm ancient binary compat overrides

Four libast hash functions/macros (which ksh93 doesn't actually use)
were overridden with the following comment:
/*
 * These following are for binary compatibility with the old hash library
 * They will be removed someday
 */
This has been there for decades, and I just received word that they
cause problems for the dtksh (CDE) developers as dtksh does call
hashlook().

src/cmd/ksh93/sh/name.c:
- Remove 'hashscope', 'hashfree', 'hashname' and 'hashlook'
  compatibility overrides.
