This patch fixes a potential memory leak in test_hs_auth_cookies() if a
test-case fails and we goto the done label where no memory clean up is
done.

It tried to pick nodes for which only routerinfo_t items are set,
but without setting UseMicroDescriptors to 0. This won't work any
more, now that we're strict about using the right descriptor types
due to 25691/25692/25213.
This changes the control_event_hs_descriptor_requested() call to add the hsdir
index optional value. v2 passes NULL all the time.
This commit creates hs_control.{c|h} that contains wrappers for the HS
subsystem to interact with the control port subsystem.
The descriptor REQUESTED event is implemented following proposal 284 extension
for v3.

Make control_event_hs_descriptor_received() and
control_event_hs_descriptor_failed() v2 specific because they take a
rend_data_t object and v3 will need to pass a different object.
No behavior change.

This is a naming refactor mostly _except_ for a the events' function that take
a rend_data_t which will require much more refactoring.
No behavior change at this commit, cleanup and renaming stuff to not be only
v2 specific.

The `test-operator-cleanup` patch, and related coccinelle patches,
don't do any checks for line length. This patch fixes the line
length issues caused by the previous commits.
This patch fixes the operator usage in src/test/*.c to use the symbolic
operators instead of the normal C comparison operators.

Add the hs_config.{c|h} files contains everything that the HS subsystem needs
to load and configure services. Ultimately, it should also contain client
functions such as client authorization.
This comes with a big refactoring of rend_config_services() which has now
changed to only configure a single service and it is stripped down of the
common directives which are now part of the generic handler.
This is ground work for prop224 of course but only touches version 2 services
and add XXX note for version 3.

This was introduced 90562fc23a adding a code
path where we pass a NULL pointer for the HSDir fingerprint to the control
event subsystem. The HS desc failed function wasn't handling properly that
pointer for a NULL value.
Two unit tests are also added in this commit to make sure we handle properly
the case of a NULL hsdir fingerprint and a NULL content as well.

The reason for making the temporary list public is to keep it encapsulated in
the rendservice subsystem so the prop224 code does not have direct access to
it and can only affect it through the rendservice pruning function.
It also has been modified to not take list as arguments but rather use the
global lists (main and temporary ones) because prop224 code will call it to
actually prune the rendservice's lists. The function does the needed rotation
of pointers between those lists and then prune if needed.
In order to make the unit test work and not completely horrible, there is a
"impl_" version of the function that doesn't free memory, it simply moves
pointers around. It is directly used in the unit test and two setter functions
for those lists' pointer have been added only for unit test.

Coverity doesn't like it when there are paths to the end of the
function where something doesn't get freed, even when those paths
are only reachable on unit test failure.
Fixes CID 1372899 and CID 1372900. Bug not in any released Tor.
Instead, refuse to start tor if any hidden service key has been used in
a different hidden service anonymity mode.
Fixes bug 20638; bugfix on 17178 in 0.2.9.3-alpha; reported by ahf.
The original single onion service poisoning code checked poisoning state
in options_validate, and poisoned in options_act. This was problematic,
because the global array of hidden services had not been populated in
options_validate (and there were ordrering issues with hidden service
directory creation).
This patch fixes this issue in rend_service_check_dir_and_add, which:
* creates the directory, or checks permissions on an existing directory, then
* checks the poisoning state of the directory, then
* poisons the directory.
When validating, only the permissions checks and the poisoning state checks
are perfomed (the directory is not modified).
In order to implement proposal 224, we need the data structure rend_data_t to
be able to accomodate versionning that is the current version of hidden
service (2) and the new version (3) and future version.
For that, we implement a series of accessors and a downcast function to get
the v2 data structure. rend_data_t becomes a top level generic place holder.
The entire rend_data_t API has been moved to hs_common.{c|h} in order to
seperate code that is shared from between HS versions and unshared code (in
rendcommon.c).
