184c76e339 hs-v3: Cleanup usage of consensus param in hs_dos.c 
This commit makes it that the hs_dos.c file only uses the consensus parameter
variables set when we initialize and when the consensus changes.

There is no need to call each time networkstatus_get_param(), which is
expensive, when we want access to a consensus value.

82639a8c7b hs-v3: Move to hs_dos.c INTRO2 defenses initialization 
A bit cleaner especially that the next commit(s) will make the consensus param
interface private to hs_dos.c so we expose as little as we can outside of the
subsystem.

e5cf1423fd man: Entry for the HS intro DoS defenses 
This also adds a "subsection" to the HIDDEN SERVICE OPTIONS section to
seperate per-service and per-instance options. It is a bit less messy this
way.

The HS DoS options are added to the per-service section.

1c554334ac test: Adapt HS DoS test to use latest parameter 
We added a flag on the circuit to know if the DoS defenses are enabled or not.
Before, it was solely the consensus parameter.

d692c5fd03 hs-v3: Encode DoS ESTABLISH_INTRO cell extension 
This commit makes tor add the DoS cell extension to the ESTABLISH_INTRO cell
if the defense is enabled on the service side with a torrc option.

Furthermore, the cell extension is only added if the introduction point
supports it. The protover version HSIntro=5 is looked for.

Fix gcc build exclude on travis
