Willy Tarreau f17f19f1a7 MINOR: buffer: introduce b_realign_if_empty()
Many places deal with buffer realignment after data removal. The method
is always the same : if the buffer is empty, set its pointer to the origin.
Let's have a function for this so that we have less code to change with the
new API.
