This commit adds the functionality for a service to build its descriptor.
Also, a global call to build all descriptors for all services is added to the
service scheduled events.

Add the main loop entry point to the HS service subsystem. It is run every
second and make sure that all services are in their quiescent state after that
which means valid descriptors, all needed circuits opened and latest
descriptors have been uploaded.
For now, only v2 is supported and placeholders for v3 actions for that main
loop callback.

It makes more sense to have the version in the configuration object of the
service because it is afterall a torrc option (HiddenServiceVersion).

The added function frees any allocated pointers in a service configuration
object and reset all values to 0.

This tests our hs_config.c API to properly load v3 services and register them
to the global map. It does NOT test the service object validity, that will be
the hs service unit test later on.
At this commit, we have 100% code coverage of hs_config.c.

Try to load or/and generate service keys for v3. This write both the public
and private key file to disk along with the hostname file containing the onion
address.

This commit adds the support in the HS subsystem for loading a service from a
set of or_options_t and put them in a staging list.
To achieve this, service accessors have been created and a global hash map
containing service object indexed by master public key. However, this is not
used for now. It's ground work for registration process.

Introduces hs_init() located in hs_common.c which initialize the entire HS v3
subsystem. This is done _prior_ to the options being loaded because we need to
allocate global data structure before we load the configuration.
The hs_free_all() is added to release everything from tor_free_all().
Note that both functions do NOT handle v2 service subsystem but does handle
the common interface that both v2 and v3 needs such as the cache and
circuitmap.

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.

One of the goals of this change is to have trunnel API/ABI being more explicit
so we namespace them with "trn_*". Furthermore, we can now create
hs_cells.[ch] without having to confuse it with trunnel which used to be
"hs_cell_*" before that change.
Here are the perl line that were used for this rename:
perl -i -pe 's/cell_extension/trn_cell_extension/g;' src/*/*.[ch]
perl -i -pe 's/cell_extension/trn_cell_extension/g;' src/trunnel/hs/*.trunnel
perl -i -pe 's/hs_cell_/trn_cell_/g;' src/*/*.[ch]
perl -i -pe 's/hs_cell_/trn_cell_/g;' src/trunnel/hs/*.trunnel
And then "./scripts/codegen/run_trunnel.sh" with trunnel commit id
613fb1b98e58504e2b84ef56b1602b6380629043.

In order to avoid src/or/hs_service.o to contain no symbols and thus making
clang throw a warning, the functions are now exposed not just to unit tests.

The "sig_len" fields was moved below the "end_sig_fields" in the trunnel
specification so when signing the cell content, the function generating such a
cell needed to be adjust.
