  Fix wrong type of lumps.

As the eoh (Enf Of Header) is determined during the on-demand parsing, the add_lump() may wrongly lable a lump as "header" or "body" (as the add_lump() may be used before the parsing reached the EOH).
So, better identify all headers asap, so the add_lump() will properly work all the time. This will not add any overhead, as in 99.9999% of the case, due the functions used in cfg, anyhow you end up parsing the whole message.

Fixes  #2144
This is a 100% safe fix, there are 0 chances for side effects.
