When there is a large number of new or modified files,
"display_all_files" takes a long time, and git-gui appears to hang.

This change limits the number of files that are displayed. This
limit can be set as gui.maxfilesdisplayed, and is 5000 by default.

A warning is shown the first time the list of files is truncated
in this GUI session. Subsequent truncations are not mentioned to
the user.
