MINOR: htx: Split on DATA blocks only when blocks are moved to an HTX message

Browse Source 
When htx_xfer_blks() is called to move blocks from an HTX message to another
one, most of blocks must be transferred atomically. But some may be splitted if
there is not enough space to move all the block. This was true for DATA and TLR
blocks. But it is a bad idea to split trailers. During HTTP parsing, only one
TLR block is emitted. It simplifies the processing of trailers to keep the block
untouched.

This patch must be backported to 1.9 because some fixes may depend on it.
