btuartd(8) should be named btattach(8) for consistency with other parts of NetBSD make btattach(8) a single-use tool for less complexity device specicific initialisation (from btuart(4)) is carried out prior to activating the line discipline (in btattach(8)), which simplifies the API somewhat and means that the user tool and the kernel do not need to be kept in sync. btuart(4) driver is much reduced; naming is made consistent and all tsleep() and delay() are removed to userland
