Fix (some of) pltcl memory usage
As reported by Bill Parker, PL/Tcl did not validate some malloc() calls
against NULL return. Fix by using palloc() in a new long-lived memory
context instead. This allows us to simplify error handling too, by
simply deleting the memory context instead of doing retail frees.
There's still a lot that could be done to improve PL/Tcl's memory
handling ...
This is pretty ancient, so backpatch all the way back.
