This adds a feature/taildrop package, a ts_omit_taildrop build tag, and starts moving code to feature/taildrop. In some cases, code remains where it was but is now behind a build tag. Future changes will move code to an extension and out of LocalBackend, etc. Updates #12614 Change-Id: Idf96c61144d1a5f707039ceb2ff59c99f5c1642f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
