Extend 'HTTP Referer statistics' to sequence HTTP Redirects

This patch adds support for sequencing HTTP Redirects. This enables
tracking of HTTP-based redirects, which may not have a Referer header.
As such, this patch also renames 'HTTP Referer statistics' to
'HTTP Request Sequences' to better reflect the more generic
functionality.

Note that this does not fully support RFC 3986. An external library like
uriparser.github.io may be a better option for efficient, full relative
HTTP URL resolution.

A Sample PCAP to test functionality is available here:

A sample PCAP to demonstrate usefulness is available here:
