The start_* functions are mere stepping stones nowadays and can be pruned. They used to contain more logic in the pre-kthread era. While here, set `cleanerproc' and `syncerproc' during the thread creation rather than expect the threads to set the proc pointer. Also, rename `sched_sync' to `syncer_thread' to reduce confusion with the scheduler-related functions. OK kettenis@, deraadt@, mpi@ Drop unnecessary `p' parameter from vget(9). 2018-05-27T06:02:14Z visa visa@openbsd.org 2018-05-27T06:02:14Z urn:sha1:08107a0b7d66fc523db27a131ca819e179fb022c OK mpi@ Clean up the parameters of VOP_LOCK() and VOP_UNLOCK().

Dangling vnodes (unlinked files still in use) and vnodes undergoing change by long-running syscalls are identified -- and such filesystems are marked dirty on-disk while we are suspended (in case power is lost, a fsck will be required). Filesystems without dangling or busy vnodes are marked clean, resulting in faster boots following "battery died" circumstances. Tested by numerous developers, thanks for the feedback.
