  build: Generate ChangeLog in 'make dist', ZIP automatically

Thanks to Matt Weinstein for the suggestion.

Change 'make dist' to generate the Git ChangeLog file, that way it doesn't
have to be manually updated nor kept in Git which causes unnecessary work.

Also change 'make dist' to invoke 'dist-zip' automatically to generate a
ZIP as well as a .tar.gz.

Thanks to http://live.gnome.org/Git/ChangeLog for the inspiration to
automatically generate ChangeLog.

This is because as it adds the 255th element at a node it attempts to calculate
the count member var which is an unsigned char via count = (255 -0) + 1; and
pass the result to realloc. Unfortunately the result is zero and realloc returns
null; the prefix_tree asserts. I have fixed it by making the count an unsigned
short.
