Updates for ace related to new searchinfiles work

Basically, avoid stack limit exceeding, and handle line updates in 100,000 chunks.

FYI: it is not so much performance as it is just ability to scale there...

Three times the same code. Can you put this in util/lang ?

[gjtorikian]

@fjakobs Done.

Generalizing is hard. Each of the three are requiring and doing something different. This is the best solution (that I could come up with) that works.

maybe it would be better to include argument array creation into library function too
lang.spliceArray(startIndex, replaceCount, array)
lang.spliceArray(startIndex, replaceCount, length)

but then i am not sure what to do about https://github.com/ajaxorg/ace/blob/master/lib/ace/edit_session.js#L1649

another thought
if document emitted only short deltas only it will need to be modified
something like this, (can the reverse order be a problem here?)

    this.insertLines = function(row, lines) {
        if (lines.length == 0)
            return {row: row, column: 0};

        if (lines.length > 0xFFFF) {
            var end = this.insertLines(row, lines.slice(0xFFFF));
            lines = lines.slice(0, 0xFFFF);
        }

        var args = [row, 0];
        args.push.apply(args, lines);
        this.$lines.splice.apply(this.$lines, args);

        var range = new Range(row, 0, row + lines.length, 0);
        var delta = {
            action: "insertLines",
            range: range,
            lines: lines
        };
        this._emit("change", { data: delta });
        return end || range.end;
    };

btw https://bugs.webkit.org/show_bug.cgi?id=80797 says that safari accepts less than 100_000 is it so or 100000 is fine?
