diff.c: remove output_prefix_length field
"diff/log --stat" has a logic that determines the display columns available for the diffstat part of the output and apportions it for pathnames and diffstat graph automatically. 5e71a84a (Add output_prefix_length to diff_options, 2012-04-16) added the output_prefix_length field to diff_options structure to allow this logic to subtract the display columns used for the history graph part from the total "terminal width"; this matters when the "git log --graph -p" option is in use. The field must be set to the number of display columns needed to show the output from the output_prefix() callback, which is error prone. As there is only one user of the field, and the user has the actual value of the prefix string, let's get rid of the field and have the user count the display width itself.
