This patch introduces a relicensed logit from the Finit[1] project. It has been rebranded as logger to complement the features implemented in the sysklogd project. Note, logger conflicts with the tool of the same name from util-linux. [1]: https://github.com/troglobit/finit Signed-off-by: Joachim Nilsson <troglobit@gmail.com>
