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.

no actual changes to the license.

this way folks who don't immediately recognize the text of the 3-clause
bsd can be reassured that we're using a standard license.

hs: v3 single onion services fall back to 3-hop intro for unreachable nodes 
Previously, v3 single onion services failed when all intro nodes were
unreachable via a 1-hop path. Now, we select intros that are only available
via a 3-hop path, and use a 3-hop path to connect to them.

Fixes bug 23507; bugfix on 0.3.2.1-alpha.
