4ebc0fa70f wgengine: incremental update of peers on network map change 
This is the first, and easier, part of incremental wireguard-go
reconfiguration. It means that a new node appearing on the
network does not cause all existing nodes to re-handshake with
the other nodes they are talking to.

(This code has been running on hello.ipn.dev for a few weeks and
peers have successfully reconnected to it through many network
map updates.)

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

5c2deb66be wgengine: remove MTU TODO. 
The MTU is currently set when creating the tun device,
elsewhere in the code. Maybe someday we'll want some kind
of per-platform MTU configuration here, but not in the
short-medium term.

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.
