Josh Bleecher Snyder	777c816b34	wgengine/wgcfg: return better errors from DeviceConfig, ReconfigDevice ... Prefer the error from the actual wireguard-go device method call, not {To,From}UAPI, as those tend to be less interesting I/O errors.

Josh Bleecher Snyder	1f6c4ba7c3	wgengine/wgcfg: prevent ReconfigDevice from hanging on error ... When wireguard-go's UAPI interface fails with an error, ReconfigDevice hangs. Fix that by buffering the channel and closing the writer after the call. The code now matches the corresponding code in DeviceConfig, where I got it right.

Josh Bleecher Snyder	fe7c3e9c17	all: move wgcfg from wireguard-go ... This is mostly code movement from the wireguard-go repo. Most of the new wgcfg package corresponds to the wireguard-go wgcfg package. wgengine/wgcfg/device{_test}.go was device/config{_test}.go. There were substantive but simple changes to device_test.go to remove internal package device references. The API of device.Config (now wgcfg.DeviceConfig) grew an error return; we previously logged the error and threw it away. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	5 years ago
