diff: add -I<regex> that ignores matching changes
Add a new diff option that enables ignoring changes whose all lines
(changed, removed, and added) match a given regular expression. This is
similar to the -I/--ignore-matching-lines option in standalone diff
utilities and can be used e.g. to ignore changes which only affect code
comments or to look for unrelated changes in commits containing a large
number of automatically applied modifications (e.g. a tree-wide string
replacement). The difference between -G/-S and the new -I option is
that the latter filters output on a per-change basis.
Use the 'ignore' field of xdchange_t for marking a change as ignored or
not. Since the same field is used by --ignore-blank-lines, identical
hunk emitting rules apply for --ignore-blank-lines and -I. These two
options can also be used together in the same git invocation (they are
complementary to each other).
Rename xdl_mark_ignorable() to xdl_mark_ignorable_lines(), to indicate
that it is logically a "sibling" of xdl_mark_ignorable_regex() rather
than its "parent".
