Warner Losh 1c7d15b030 Make device_busy/unbusy work w/o Giant held ... The vast majority of the busy/unbusy users in the tree don't acquire Giant before calling device_busy/unbusy. However, if multiple threads are opening a file, say, that causes the device to busy/unbusy, then we can race to the root marking things busy. Move to using a reference count to keep track of how many times a device_t has been made busy. Use that count to make the same decisions that we'd make with the old device state. Note: gpiopps.c uses D_TRACKCLOSE. Others do as well. However, there's a known race with closes that will be corrected for all the drivers that do this in a future commit.
