Add support for scoping and symbol binding
As a first step towards stand-alone sets, add support for scoping and
binding symbols. This will be used for user-defined constants, as well
as declarations of modifiable (stand-alone) sets once the kernel side
is ready.
Scopes are currently limited to three nesting levels: the global scope,
table block scopes and chain block scopes.
