[dev] enhance riot; ddns avoid burst (#38)

* riot: add . for .ibd and non for proxied

* riot: 'user@..' to overwrite username, '...:22' to overwrite port, treat the arg as server name if it doesn't match any preset, sshl can accept only a port number and default to use localhost

* update.sh: ddns sleep for random seconds to avoid burst

* riot: support zssh and sftp, and set ssh options according to trust settings

* riot: add scp

* riot: support jump servers, sep by commas

* common.sh: argparser supports -d/--dev and -D/--dry-run

* install.sh: remove -s/--secure because of no use

* riot: if remote ends with dot, treat it as a full-hostname; add tests

* sagent.sh: refuse to work on windows
