Sometimes we want to be able to pipe the output of btmon to a
non-terminal device. The current fallback width is usually not long
enough so this patch adds an option to specify the column width. This is
especially needed for text logs from bluetoothd.

I prefer that we use a bit more descriptive variable names here. So either num_columns or pager_width or something like that.
