Add a WebDAV-based folder sharing mechanism that is exposed to local clients at 100.100.100.100:8080 and to remote peers via a new peerapi endpoint at /v0/tailfs. Add the ability to manage folder sharing via the new 'share' CLI sub-command. Updates tailscale/corp#16827 Signed-off-by: Percy Wegmann <percy@tailscale.com>
