Before this the CLOCK_MONOTONIC used by the FUTEX_WAIT_BITSET op. When the FUTEX_CLOCK_REALTIME is specified the timeout is an absolute time, not a relative time. Rework futex_wait to handle this. On the side fix the futex leak in error case and remove useless parentheses. Properly calculate the timeout for the CLOCK_MONOTONIC case.

Some Linux futex ops atomically verifies that the futex address uaddr (uval) contains the value val. Comparing signed uval and unsigned val may lead to an unexpected result, mostly to a deadlock. So copyin uaddr to an unsigned int to compare the parameters correctly. While here change ktr records to print parameters in more readable format.

Similar to ktrace it can apply a change to all existing descendants of a process as well as future descendants. - Add a new procctl(2) system call that provides a generic interface for control operations on processes (as opposed to the debugger-specific operations provided by ptrace(2)). procctl(2) uses a combination of idtype_t and an id to identify the set of processes on which to operate similar to wait6(). - Add a PROC_SPROTECT control operation to manage the protection status of a set of processes. MADV_PROTECT still works for backwards compatability. - Add a p_flag2 to struct proc (and a corresponding ki_flag2 to kinfo_proc) the first bit of which is used to track if P_PROTECT should be inherited by new child processes.
