expr: Replace expression engine
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.
