Fix line length warnings

Update the Checkstyle configuration to only warn on lines that exceed
150 characters.

In code reviews we usually ask people to wrap lines at around 80 columns,
but there are too many existing long lines (between 80 and 150) to bother
fixing them all now.

Only wrap the ones that are egregiously long (i.e. more than 150) and add
suppressions for the ones that cannot be wrapped, for example containing
long URLs.
