These crates had no changes until just a moment ago. But since
we updated the versions on some of their dependents, they have now
changed themselves. Thus they get patchlevel bumps.
```
tor-rtmock
tor-protover
tor-socksproto
tor-consdiff
tor-chanmgr
tor-dirclient
tor-hsservice
```
For these crates, the changes are nontrivial, so we
_do_ bump the versions on which their dependent crates depend.
Fortunately, since they are all pre-1.0, we don't need to
distinguish semver-additions from other changes. (Except for arti,
which _is_ post-1.0, but gets a patchlevel bump anyway.)
These are unstable crates with breaking changes:
```
tor-hscrypto
tor-hsclient
```
These have new or extended APIs:
```
safelog
tor-bytes
tor-cell
tor-linkspec
tor-llcrypto
tor-proto
tor-cert
arti-client
```
These have new unstable APIs or features:
```
tor-netdoc
tor-circmgr (also broke some unstable APIs)
arti (is post-1.0)
```
These have bugfixes only:
```
caret
tor-dirmgr
```
Their dependents are _not_ updated to a more recent version.
These bumped the version of a dependency that they don't expose
```
tor-rtcompat
fs-mistrust
```
This one had internal refactoring:
```
tor-netdir
```
These had trivial changes only:
```
tor-checkable
tor-ptmgr
tor-guardmgr
arti-hyper
arti-bench
arti-testing
```
This introduces the `NetdocBuilder` trait described in
`netdoc-builder.md` and a new `tor-netdoc::doc::hsdesc::build` module,
which exports the `HsDescBuilder`. Hidden services will use
`HsDescBuilder` to build and encode hidden service descriptors.
There are several TODOs in the code that I'm planning to address
separately.
Partially addresses #745.

This new function combines "sending a message" and "accepting
replies in a stream" into a single call, so that there is no gap
between when the message is sent and the replies are available.
There are a number of compromises here, in order to avoid API
proliferation. I've tried to contain them as best I can.
See comments for additional design discussion.
Explicit drops don't work. Instead, introduce a scope.
We need two scopes, actually: one where we do the initial table
wrangling, and one for the retries after relock.
So we must put the meat in a closure so we can reuse it.
And we must return the flow control as an enum. Bah, etc.
Avoid reformatting this for the moment. This makes the delta legible...
Provide a more cookied "secret keys for use to connecting to a
particular HS" type, with a builder.
This wants to use config stuff, so oughtn't to be in tor-*crypto.
The individual types remain there.
These crates didn't have any changes until now, when I bumped
the versions of some other crates they depend on:
tor-consdiff
arti-hyper
arti-bench
arti-testing
These crates have had small code changes, but no API additions:
tor-config
tor-socksproto
tor-cert
tor-chanmgr
tor-ptmgr
tor-guardmgr
tor-circmgr
tor-dirclient
tor-dirmgr
arti
tor-hsservice
tor-congestion
These crates have had API extensions:
fs-mistrust
tor-llcrypto
tor-bytes
tor-checkable
tor-linkspec
tor-netdoc
tor-persist
arti-client
These are API breaks, but the crates themselves are currently
100% experimental, so there's no need to bump the minor versions
according to our semver rules.
We now manipulate raw relay cell bodies as (an alias for)
`Box<[u8;509]>` rather than as (an alias for) `[u8;509]`. This
enables us to do much less copying. It will become more important
soon, as we defer parsing relay cell bodies even longer.
Related to #7.
We also use SliceWriter to avoid allocating a Vec<> for every relay
message we want to encode, and instead encode directly into the
cell.
Locally, the only functional effect is that now we refuse to handle
non-whole-number-of-minutes lengths - but since the consensus
parameter can't represent those, there's no overall functional change.
There are some places where I note certificates which are not
currently validated, because there is no cryptographic point in
doing so. We should either document that this is okay, or validate
the certificates anyway.
This code might benefit from refactoring to make it prettier.
