Subject: various posts: Implement assignment parsing for typeset.

Typeset assignments now work like raw assignments except
for no "+=" and no GLOB_ASSIGN.

Documented in typeset builtin doc and mentioned in release notes.

Tests to ensure basic sanity.

Enabled by default, can be turned off by "disable -r" with typeset
family of commands.
