4b090e41ff Add an explicit credential argument to alq_open() to allow the caller to 
specify what credential to use when authorizing vn_open() and later
write operations, rather than curthread->td_ucred.

When writing KTR traces to an ALQ, specify the credential of the thread
generating the sysctl request.

30fd5d085d - Reset the free ent to NULL if we have consumed the last free entry. This 
fixes a problem where we would overwrite old data if we ran out of free
   entries.

9405072a95 - Add an asynchronous fixed length record logging mechanism called 
ALQ (Asynch. Logging Queues).  ALQ supports many seperate queues with
   different record and buffer sizes.  It opens and logs to any vnode so
   it can be used with character devices as well as regular files.
