add WITNESS support to barriers modelled on the timeout stuff visa did. if a taskq takes a lock, and something holding that lock calls taskq_barrier, there's a potential deadlock. detect this as a lock order problem when witness is enable. task_del conditionally followed by taskq_barrier is a common pattern, so add a taskq_del_barrier wrapper for it that unconditionally checks for the deadlock, like timeout_del_barrier. ok visa@

add taskq_barrier taskq_barrier guarantees that any task that was running on the taskq has finished by the time taskq_barrier returns. it is similar to intr_barrier. this is needed for use in ifq_barrier as part of an upcoming change.

Remove useless quoting from .Fo and .Fn function names, to prevent development of a cargo cult in case people look at existing files for examples. This achieves a consistent .Fo and .Fn quoting style across the whole tree.

task_add takes a flags argument now. this throws some words at it, maybe some will stick.

remove the second void * argument on tasks. when workqs were introduced, we provided a second argument so you could pass a thing and some context to work on it in. there were very few things that took advantage of the second argument, so when i introduced pools i suggested removing it. since tasks were meant to replace workqs, it was requested that we keep the second argument to make porting from workqs to tasks easier. now that workqs are gone, i had a look at the use of the second argument again and found only one good use of it (vdsp(4) on sparc64 if you're interested) and a tiny handful of questionable uses. the vast majority of tasks only used a single argument. i have since modified all tasks that used two args to only use one, so now we can remove the second argument. so this is a mechanical change. all tasks only passed NULL as their second argument, so we can just remove it. ok krw@

introduce a CONTEXT section that describes where you can call the bits of the API from. task_add is the first manpage to get this, but hopefully not the last. inspired by the CONTEXT section in solaris, and introduced here with the blessing of deraadt@, jmc@, and ingo@. discussed with jmc@ and ingo@
