Maximize use of the 'var' keyword.

This is used whenever a variable:
1. is declared and initialized in the same line
AND
2. would not avoid a copy by using the 'unowned'. In the future, we may be able
to declare variables 'unowned var', in which case this point won't matter. See
bgo#638199.

The net benefit is less noise on variable declaration lines.

 6. Private and internal class functions should begin with a _ (public functions
    should not begin with a _). This is to make non-public functions instantly
    recognizable as such (which helps readability).
