Replace map() and filter() with comprehensions

This had the advantage of being more readable to people without a
functional programming background, and it avoids the need to use lambdas
which are both slow and have many corners in python. In a few cases it
also allows us to use a generator expression instead of a materialized
list, which save some memory.
