Bump to 8.5.16 for release.
Revert the EOLFIX changes of checkin [a803608ed5] (2013-10-28).
They do not work on the one machine where they must -- the release managers!
Appears that the NATIVE_TCLSH support isn't found on the 8.5 branch, so we
shouldn't expect to use it.

Hum. Really merge trunk.
More optimized non-BC [string cat] using Tcl_AppendObjToObj() - thx Donal
Add constant folding to [string cat]. Mixed-quote idiom is now compiled to a single push.
