* Reorganize the book.
This PR has one unfortunate change, which is that the README.md and
CONTRIBUTING.md files in the book are symlinks to files in the parent
directory. The motivation for this is to ensure that we don't maintain two
copies of the same data, and that the landing page of the website matches the
landing page of the Github repo, etc. However, I'm not sure whether these
symlinks will work correctly on Windows.
The alternatives are:
- Duplicate the contents of the files and expect that people will know to keep
them in sync;
- Use relative links `../../README.md` in the `SUMMARY.md`. This seemed like
it caused mdbook to dump the rendered files into the repository root rather
than keeping them in the `book` directory.
- Use a symlink (chosen option). This may not work on Windows but I think that
the worst outcome would be that the book would be unbuildable unless someone
used WSL or something. This seems like the least bad option.
* Remove symlinks in favor of #include
Turns out the symlinks aren't required!
Closes#536.
This removes:
- the user-agent (we can add a mechanism to specify extra BIP14 components later, if any users ask us for that feature);
- the EWMA parameters (these were put in the config just to avoid making a choice);
- the peer connection timeout (we can change the default value if anyone ever has a problem with it);
- the peer set request buffer size (setting this too low can make the application deadlock);
The new peer interval is left in.
* Split tracing component code into modules.
* Repatriate Tracing and simplify config handling.
We upstreamed our Tracing component, expecting not to have to exert fine
control over the tracing settings. But this turned out not to be the case, and
now that we want to do other things (flamegraphs, journalctl, opentelemetry,
etc), we end up with really awkward code (as in the current flamegraph
handling).
This also makes use of the changes to `init()` to load the config early to pass
configuration data into the components, which avoids the need for the
refactoring in #775.
Finally, we restore support for the `-v` flag when the filter is unset. Closes#831.
* Disable tracing and metrics endpoints by default.
Closes#660.

* Load tracing filter only from config and simplify logic.
* Configure the state storage in the config, not an environment variable.
This also changes the config so that the path is always set rather than being
optional, because Zebra always needs a place to store its config.
The Heartwood upgrade changes the meaning of the hashFinalSaplingRoot to
hashLightClientRoot. Since we don't know the network upgrade heights in
zebra-chain, we just use [u8; 32] for now.
* add zebrad acceptance tests
* add custom command test helpers that work with kill
* add and use info event for start and seed commands
* combine conflicting tests into one test case
