Resurrect `textproc/xxdiff' and `textproc/xxdiff-scripts' which were removed

from the tree when Qt 3.x had reached EoL.  Version 4.0 adds support for Qt4
now and thus allows to revive the port(s).  While here, modernize Makefiles,
define LICENSE (GPLv2), clean up dependencies, and augment port description.

+xxdiff is a graphical tool for viewing the differences between two or three
+files, or between two directories, and can produce a merged version thereof.
+
+Some of its features:
+
+  - Comparing two files, three files, or two directories (shallow and
+    recursive)
+  - Horizontal diffs highlighting
+  - Files can be merged interactively and resulting output visualized
+    and saved
+  - Has features to assist in performing merge reviews/policing
+  - Can unmerge CVS conflicts in automatically merged file and display
+    them as two files, to help resolve conflicts
+  - Uses external diff program to compute differences: works with GNU
+    diff, SGI diff and ClearCase's cleardiff, and any other diff whose
+    output is similar to those
+  - Fully customizable with a resource file
+  - Look-and-feel similar to Rudy Wortel's/SGI xdiff; it is desktop
+    agnostic (i.e. will work equally well with KDE or GNOME)
+  - Features and output that ease integration with scripts
