To be more compatible with go and makes more sense for cleanup

- onleave is now defer
- $onleave is now $jim::defer
- invoke deferred scripts in reverse order
- improve some tests
- remove defer support from namespace eval

New, experimental feature that allows commands to run
when a proc or interpreter exits.

If the $onleave variables exists at proc or interp exit,
it is treated as a list of scripts to evaluate.

The [onleave] command is a helper to add scripts to $onleave.

See tests/onleave.test

This test is essentially the same as timer-6.4 except with
tighter timing requirements. Remove it to prevent spurious failures.

Rework the expression engine to use recursive descent evaluation rather than
a shunting yard algorithm. Among other things, it is easier to make lazy operators
and the ternary operator work correctly.

In particular, the following expression no longer crashes: $(99?9,99?9:*9:999)?9)

And the code is now smaller.

When duplicating interpolated object type, need to increment
ref count of the key to offset the decrement during free.

Also remove type-specific dup for dict-substitution which is not
needed since it does nothing different from the default dup.
