also introduces a new `netlink-request` crate to help modularize the netlink code. this currently depends on a fork of the `netlink` project, but we should be able to use the official version soon.
* client: allow config/data dirs to be changed
* server: allow config/data dirs to be changed
* meta: cargo clippy & cargo fmt
* shared: use const for Duration instead of lazy_static
added to `innernet {up,fetch,install}`:
--no-nat-traversal: Doesn't attempt NAT traversal
(prevents long time delays in execution of command)
--exclude-nat-candidates: Exclude a list of CIDRs from being
considered candidates
--no-nat-candidates: Don't report NAT candidates.
(shorthand for '--exclude-nat-candidates 0.0.0.0/0')
Closes#160
clap (used by StructOpt) doesn't escape double-quotes inside the
rustdocs that is uses to generate completion helptext. Rather than wait
on them, it's simpler to just avoid double-quotes for now at least.
Closes#156
Before, only clients would report local addresses for NAT traversal. Servers should too! This will be helpful in common situations when the server is run inside the same LAN as other peers, and there's no NAT hairpinning enabled (or possible) on the router.
closes#146
This change adds the ability for peers to report additional candidate endpoints for other peers to attempt connections with outside of the endpoint reported by the coordinating server.
While not a complete solution to the full spectrum of NAT traversal issues (TURN-esque proxying is still notably missing), it allows peers within the same NAT to connect to each other via their LAN addresses, which is a win nonetheless. In the future, more advanced candidate discovery could be used to punch through additional types of NAT cone types as well.

* Tidy code a bit thanks to clippy
Clippy 1.54 newly detects some redundant constructs, that's nice.
sort_unstable() should yield exact same results as sort() for `Vec<&str>`
and could be faster, clippy says.
* Add clippy to CI
The past behavior of clients was to, on every fetch from the server, update each of its peer's endpoints with the one reported from the server. While this wasn't a problem on certain types of NATs to help with holepunching, in some situations it caused previously working connections to no longer work (when one peer had a port-restricted or symmetric cone type NAT).
This commit adds a subcommand to both the client and server to allow
changing the name of a peer. The peer retains all the same attributes as
before (public keys, IPs, admin/disabled status, etc.).
Closes#87
This subcommand takes a shell as an argument and generates shell
completions for that shell to stdout.
example:
```
$ innernet completions bash
OR
$ innernet-server completions bash
```
This commit adds a `delete-cidr` to both the client and server. It walks
through the prompts just like adding a CIDR.
Only eligible CIDRs are presented to the user. Eligibilty requires:
- CIDR has no child CIDRs
- CIDR has no assigned peers
Closes#23
