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.

+The builtins declare, export, local, readonly and typeset
+now have corresponding reserved words.  When used in
+this form, the builtin syntax is extended so that assignments
+following the reserved word are treated similarly to
+assignments that appear at the start of the command line.
+For example,
+  local scalar=`echo one word` array=(several words)
+creates a local "scalar" containing the text "one word"
+and an array "array" containing the words "several"
+"words".
