BUG/MEDIUM: htx: Fully update HTX message when the block value is changed

Everywhere the value length of a block is changed, calling the function
htx_set_blk_value_len(), the HTX message must be updated. But at many places,
because of the recent changes in the HTX structure, this update was only
partially done. tail_addr and head_addr values were not systematically updated.

In fact, the function htx_set_blk_value_len() was designed as an internal
function to the HTX API. And we used it from outside by convenience. But it is
really painfull and error prone to let the caller update the HTX message. So
now, we use the function htx_change_blk_value_len() wherever is possible. It
changes the value length of a block and updates the HTX message accordingly.

This patch must be backported to 2.0.
