OpenBSD uses sysctl with struct uvmexp to get information from the
virtual memory system of the kernel. Add type Uvmexp and the
SysctlUvmexp function to query this information.
This will be used in github.com/tklauser/go-sysconf to get
_SC_AVPHYS_PAGES on OpenBSD.

These sysctl strings were lost in CL 114075 which updated openbsd/amd64
to OpenBSD 6.3. Re-add them by adding uvm/uvmexp.h to mksysctl_openbsd.pl.
The defines for the VM_* constants were moved to this header in
OpenBSD 6.3.

NetBSD uses sysctl with struct clockinfo to get clock rate information

If a system has the ability to disable some cores, as on
ppc64 with the ppc64_cpu command, then TestSchedSetaffinity will
fail if the CPUset passed to Setaffinity includes one that has
been disabled.
This adds a check to use values from the oldMask, which are the valid
cores returned from Getaffinity, to pass to Setaffinity.

Add syscall wrappers, error constants and types for linux/riscv64
Switch docker image to Ubuntu 18.10 in order to get qemu supporting
riscv64. Also set the uname release string for qemu to 4.15 (the first
Linux kernel version with riscv64 support), because otherwise running
the generating C program in mkerrors.sh on a host with an older kernel
would fail with a "FATAL: kernel too old".
Note that linux/riscv64 is currently only usable using gccgo.

The Linux kernel faccessat system call does not take a flags parameter.
The flag parameter to the C library faccessat function is implemented in C.
The unix.Faccessat function takes a flags parameter. In older releases
we have passed the flags parameter to the kernel, which ignored it.
In CL 119495 we started returning an error if any flags were set.
That seems clearly better than ignoring them, but it turns out that some
code was using the flags. The code was previously subtly broken.
Now it is obviously broken. That is better, but we can do better still:
we can implement the flags as the C library does. That is what this CL does.
