A new diffcore filter diffcore-order is introduced. This takes
a text file each of whose line is a shell glob pattern. Patches
that match a glob pattern on an earlier line in the file are
output before patches that match a later line, and patches that
do not match any glob pattern are output last.
A typical orderfile for git project probably should look like
this:
