* include/abg-diff-utils.h (point::set): New overload..
(point::{add, operator<, operator>, operator<=, operator>=}): New
methods.
(point::operator!=): Constify.
(point::operator==): Constify. Cleanup.
(point::operator=): Keep emptiness.
(class snake): New class definition
(d_path_vec::{over_bounds, offset}): New methods.
(d_path_vec::check_index_against_bound): Don't take a bound
parameter anymore. Use the new over_bound method above. Fix up
error reporting.
(d_path_vec::d_path_vec): Fix d_path_vec size allocation.
(d_path_vec::operator[]): Use the d_path_vec::at method to check
all accesses against the bounds. This is slower, but at least we
can expect to have something that is more robust. We can remove
the bound checking later when we are sure the code has been tested
enough. Also use the new offset() method.
(d_path_vec::at): Take long long.
(ends_of_furthest_d_paths_overlap): Constify input parameters.
(end_of_fr_d_path_in_k, end_of_frr_d_path_in_k_plus_delta): Take
an instance of the new snake in parameter, rather than a bare end
point that wasn't carrying enough information about the snake.
Record the snake which consists of up to four points: a begin
point, an intermediate point, a diagonal start point and an end
point. Return that snake upon successful completion.
(compute_middle_snake): Take an instance of snake, rather than the
two points that were supposed to represent a snake and with which
we were loosing information before. Revisit/simplify the logic of
this function; this literally goes forward or in reverse, gets the
resulting snake returned by the end_of_fr_d_path_in_k and
end_of_frr_d_path_in_k_plus_delta functions, detect if these snakes
overlap and just return the current snake. Much simpler. The
caller now gets a snake, which has much more information than the
previous snake approximation made of just two points. Bonus
point, this follows almost to the word, what the paper says.
(maybe_record_match_point, find_snake_start_point): Remove these
as there are not used by compute_middle_snake anymore.
(print_snake, ses_len): Update these to take/handle a snake.
(snake_end_points): New declaration.
(compute_diff): When we are getting an empty first sequence, this
means that we are inserting the second sequence *before* the
beginning of the first sequence; keep this information by setting
the insertion point index to -1, rather than zero. Update this to
get/handle snakes, rather than free points vaguely representing
snakes. Now that compute_middle_snake returns real snakes, handle
the information we are getting. Basically for edit scripts of
length equal to 1, as the snake carries all the necessary
information about the non-diagonal edge (as well as the diagonal
edges), we (can) now precisely update the current edit script (as
well as the longest common sub-sequence). For edit scripts of
length greater than 1, better at which points to divide the
problem and consequently, at which points to conquer it back --
better following The Paper to the letter.

snake.

function sections; we were mistakenly using the variables for the

autoconf for building from source is no big deal today, and typing
"autoreconf" is not hard to do, really. And it saves the
developers for having to update a bunch of boilerplate
automatically generated files into the source control system; this
is really unnecessary noise and it is a commonly accepted good
practice to avoid doing it these days. To help people who do not
know how to handle this, there is a COMPILING file in the source
