72cae5504c wgengine: generate and plumb router.Settings in from ipn.
This saves a layer of translation, and saves us having to
pass in extra bits and pieces of the netmap and prefs to
wgengine. Now it gets one Wireguard config, and one OS
network stack config.

f53e78e0d5 wgengine: don't lose filter state on filter reconfig.
We were abandoning the UDP port LRU every time we got a new packet
filter from tailcontrol, which caused return packets to suddenly stop
arriving.

addbdce296 wgengine, ipn: include number of active DERPs in status
Use this when making the ipn state transition from Starting to
Running. This way a network of quiet nodes with no active
handshaking will still transition to Active.

79295b1138 wgengine: simplify, change some signatures
* make RouterGen return an error, not take both tunname and tundev
* also remove RouteGen taking a wireguard/device.Device; currently unused
* remove derp parameter (it'll work differently)
* unexport NewUserspaceRouter in per-OS impls, add documented wrapper

a07906d1d8 wgengine: make SetRoutesFunc less appealing to use.
It exists as a way to glue the mac-specific xcode logic with the OSS
logic, and shouldn't be used by anything but the xcode glue.
