Tailscale: openwrt package

[crawshaw]

User reports say that tailscale works on openwrt with the static arm binary. The only extra step that's required is opkg install kmod-tun.

(This is complicated by the fact that there's more than one flavor of openwrt.)

Notes to self, looking in to how I can run OpenWRT in a VM:

https://downloads.openwrt.org/releases/19.07.3/targets/x86/64/

Yes, yes it does :)

That said, I needed opkg install ca-bundle kmod-tun on OpenWrt 19.07.4. ca-bundle is commonly installed to work from the command line though; I probably would have missed it too if I hadn't broken my firmware while experimenting and needed to reinstall.

@willangley, that's great, thanks!

@willangley, I pushed https://github.com/tailscale/tailscale/commit/5d8b88be8852fbdcdf90f96094549d78901ef4b1 to make things easier for people in the future too.

The new version has been tested. The installation can be used in OpenWrt R20.7.1.

But the open boot and pre-authentication keys are missing

Start and start also need script operation, can this be integrated;

It's rather painless to package for OpenWRT, I'm happy to assist.
A web interface like luci-app-tailscale would be an amazing carrot for adoption.

There is no problem with the installation. It is mainly the integration of startup after boot, and I hope it can be integrated into the package. After installation, it can be started
