MEDIUM: htx: make htx_add_data() never defragment the buffer

Now instead of trying to fit 100% of the input data into the output
buffer at the risk of defragmenting it, we put what fits into it only
and return the amount of bytes transferred. In a test, compared to the
previous commit, it increases the cached data rate from 44 Gbps to
55 Gbps and saves a lot in case of large buffers : with a 1 MB buffer,
uncached transfers jumped from 700 Mbps to 30 Gbps.
