runtime: use cpuset_getaffinity for runtime.NumCPU() on FreeBSD In FreeBSD when run Go proc under a given sub-list of processors(e.g. 'cpuset -l 0 ./a.out' in multi-core system), runtime.NumCPU() still return all physical CPUs from sysctl hw.ncpu instead of account from sub-list. Fix by use syscall cpuset_getaffinity to account the number of sub-list.

runtime: sleep on CLOCK_MONOTONIC in futexsleep1 on freebsd In FreeBSD 10.0, the _umtx_op syscall was changed to allow sleeping on any supported clock, but the default clock was switched from a monotonic clock to CLOCK_REALTIME. Prior to 10.0, the __umtx_op_wait* functions ignored the fourth argument to _umtx_op (uaddr1), expected the fifth argument (uaddr2) to be a struct timespec pointer, and used a monotonic clock (nanouptime(9)) for timeout calculations. Since 10.0, if callers want a clock other than CLOCK_REALTIME, they must call _umtx_op with uaddr1 set to a value greater than sizeof(struct timespec), and with uaddr2 as pointer to a struct _umtx_time, rather than a timespec. Callers can set the _clockid field of the struct _umtx_time to request the clock they want.

runtime: for kqueue treat EVFILT_READ with EV_EOF as permitting a write On systems that use kqueue, we always register descriptors for both EVFILT_READ and EVFILT_WRITE. On at least FreeBSD and OpenBSD, when the write end of a pipe is registered for EVFILT_READ and EVFILT_WRITE events, and the read end of the pipe is closed, kqueue reports an EVFILT_READ event with EV_EOF set, but does not report an EVFILT_WRITE event. Since the write to the pipe is waiting for an EVFILT_WRITE event, closing the read end of a pipe can cause the write end to hang rather than attempt another write which will fail with EPIPE. Fix this by treating EVFILT_READ with EV_EOF set as making both reads and writes ready to proceed. The real test for this is in CL 71770, which tests using various timeouts with pipes.
