Recently, QCS Rx allocation buffer method has been improved. It is now possible to allocate multiple buffers per QCS instances, which was necessary to improve HTTP/3 POST throughput. However, a limitation remained related to the emission of MAX_STREAM_DATA. These frames are only emitted once at least half of the receive capacity has been consumed by its QCS instance. This may be too restrictive when a client need to upload a large payload. Improve this by adjusting MAX_STREAM_DATA allocation. If QCS capacity is still limited to 1 or 2 buffers max, the old calcul is still used. This is necessary when user has limited upload throughput via their configuration. If QCS capacity is more than 2 buffers, a new frame is emitted if at least a buffer was consumed. This patch has reduced number of STREAM_DATA_BLOCKED frames received in POST tests with some specific clients.
