This is part of a change to convert all usages of 'var' with either
'let' or 'const'. This takes a conservative approach for 'const' where
it will only be used for aliases and storing the "original" values in
tests.

This digests and organizes many of the automatic settings in eslint,
and changes several of them to be more strict. This also fixes the
following errors:
- array-callback-return
- no-catch-shadow
- no-multi-spaces
- no-new
- no-throw-literal
- no-useless-call
- no-useless-concat
- no-useless-return
Several checks have been organized into a group of checks we should
use, but need more time to implement and fix. Some other checks have
been delegated to the Closure compiler, which can more precisely
whitelist exceptions.
