[HICN-411] Change how manifests are requested
This patch introduces a new way of requesting manifests such that
all the segments they contain fill the current transport window.
When a manifest (M) is received, we compute
L = last_segment_requested + current_window_size.
L is therefore equal or greater than the last segment of the
current window.
Then we compare L to the suffix of the next manifest that will
be (potentially) requested.
If L > next_manifest, it means that the last segment of the window is
greater than the first segment contained in the next manifest.
Therefore we request manifests until L <= next_manifest, ie until the
manifests would cover the entire window.
If L <= next_manifest, then all the manifests that were requested
already cover the window, so there's no need to request more. However
if the next manifest immediately follows the current one (M), we still
need to request it so that the content suffix queue is correctly
updated.
