Make this a bit more safe with at least type checking of the pointers

743d0b9d91 hs-v3: Implement HS_DESC REQUESTED event
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.

e7d606900e control: Rename two HS v2 specific functions
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.

242ddc85c8 control: Refactor HS_DESC events functions to not be v2 specific
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.

1969d57363 Change our build process to run Cargo from inside the build tree
Instead of using the cwd to specify the location of Cargo.toml, we
use the --manifest-path option to specify its location explicitly.

This works around the bug that isis diagnosed on our jenkins builds.

c3c0a05f51 Add a new notion of "stamps" to be a fast 32-bit monotonic timestamp
The goal here is to replace our use of msec-based timestamps with
something less precise, but easier to calculate.  We're doing this
because calculating lots of msec-based timestamps requires lots of
64/32 division operations, which can be inefficient on 32-bit
platforms.

We make sure that these stamps can be calculated using only the
coarse monotonic timer and 32-bit bitwise operations.

636eec32bf test: Improve the inbound channel cell test
First, that test was broken from the previous commit because the
channel_queue_cell() has been removed. This now tests the
channel_process_cell() directly.

Second, it wasn't testing much except if the channel subsystem actually went
through the cell handler. This commit adds more checks on the state of a
channel going from open, receiving a cell and closing.

Third, this and the id_map unit test are working, not the others so they've
been marked as not working and future commit will improve and fix those.

6d1ea7766b channel: Remove unused write cell functions
The channel_write_cell() and channel_write_var_cell() can't be possibly called
nor are used by tor. We only write on the connection outbuf packed cell coming
from the scheduler that takes them from the circuit queue.

This makes channel_write_packed_cell() the only usable function. It is
simplify and now returns a code value. The reason for this is that in the next
commit(s), we'll re-queue the cell onto the circuit queue if the write fails.

Finally, channel unit tests are being removed with this commit because they do
not match the new semantic. They will be re-written in future commits.

46a0709261 channel: Remove incoming/outgoing queue
For the rationale, see ticket #23709.

This is a pretty massive commit. Those queues were everywhere in channel.c and
it turns out that it was used by lots of dead code.

The channel subsystem *never* handles variable size cell (var_cell_t) or
unpacked cells (cell_t). The variable ones are only handled in channeltls and
outbound cells are always packed from the circuit queue so this commit removes
code related to variable and unpacked cells.

However, inbound cells are unpacked (cell_t), that is untouched and is handled
via channel_process_cell() function.

In order to make the commit compile, test have been modified but not passing
at this commit. Also, many tests have been removed but better improved ones
get added in future commits.

This commit also adds a XXX: which indicates that the handling process of
outbound cells isn't fully working. This as well is fixed in a future commit.

Finally, at this commit, more dead code remains, it will be cleanup in future
commits.

Fixes #23709

old bridge descriptors are cached, but they are not in use.

49f21b6ba3 control: Support HSv3 interface for ADD_ONION
At this commit, the key handling and generation is supported for a v3 service
(ED25519-V3). However, the service creation is not yet implemented. This only
adds the interface and code to deal with the new ED25519-V3 key type.

Tests have been updated for RSA key type but nothing yet for ED25519-v3.
