On macOS, the SysctlKinfoProcSlice() function may be used to fetch the contents of the process table. As the process table may grow between the first and second call to sysctl(), the second call may fail with ENOMEM. In that case we simply need to retry.

The setattrlist() function can be used to mutate the attributes of files through a single call. For example, one can perform a chmod(), chown(), chflags(), [...] all at once.
This change also adds bindings for the UF_* and SF_* flags that are accepted by chflags(). This makes it possible to use setattrlist() to perform the equivalent of lchflags(), for which we currently have no binding.

On Linux, we can extract a list of all the processes on the system by
calling readdir() against /proc. On BSD-like systems, this information
needs to be extracted from sysctl in the form of kinfo_proc structures.
This change adds bindings for this structure and adds a method for
reading an array of these structures from sysctl.

The Go "os" package already provides bindings for SEEK_CUR, SEEK_SET and
SEEK_END. Most operating systems also support SEEK_HOLE and SEEK_DATA,
which you can use to skip sparse regions in a file. Let's add bindings,
so we can also do this from within Go.
