* core: Refactor listeners; use SO_REUSEPORT on Unix
Just an experiment for now
* Fix lint by logging error
* TCP Keepalive configuration (#4865)
* initial attempt at TCP Keepalive configuration
* core: implement tcp-keepalive for linux
* move canSetKeepAlive interface
* Godoc for keepalive server parameter
* handle return values
* log keepalive errors
* Clean up after bad merge
* Merge in pluggable network types
From 1edc1a45e3aee1f7d86b68c3ddaf2fd16ba8ab73
