Willy Tarreau 15530d28a4 MEDIUM: compression: don't send leading zeroes with chunk size
Till now we used to rely on a fixed maximum chunk size. Thanks to last
commit we're now free to adjust the chunk's length before sending the
data, so we don't have to use 6 digits all the time anymore, and if
one wants buffers larger than 16 MB it is now possible.
