This patch implements the DAP setVariable request. setVariable is a bit odd in that it specifies the variable to modify by passing in the variable's container and the name of the variable. This approach can't handle variable shadowing (there are a couple of open DAP bugs on this topic), so this patch renames duplicates to avoid the problem.
