b44545bcd3 unix: add missing rtnetlink IFLA_* constants on Linux 
A number of IFLA_* constants have been added since the last time this
list was generated. In addition, IFLA_INFO_* is a different enum, so
we'll add the missing values for there as well.

to generate the Ustat_t wrapper type. Since Linux still provides the
syscall, let's not break this functionality and add a private copy of
struct ustat so Ustat_t can still be generated.

fff93fa7cd unix: add Statx on Linux 
statx(2) allows to get enhanced file status information (not currently
available through the existing stat syscalls), lightweight stat,
heavyweight stat. The Statx_t type used by Statx has consistent field
sizes on all arches (with year-2038-capable timestamps) and is closer to
the BSD implementation of Stat_t.

See http://man7.org/linux/man-pages/man2/statx.2.html for details. The
syscall was added in Linux kernel 4.11.

See https://github.com/tklauser/statx for an example of how this
function and types can be used to report stat(1)-like file status
information.

12d9d5b281 unix: add SchedGetaffinity and SchedSetaffinity on Linux 
SchedGetaffinity and SchedSetaffinity are used to get and set a thread's
CPU affinity mask.

See http://man7.org/linux/man-pages/man2/sched_setaffinity.2.html for
details.

Also add a manual implementation of CpuSet_t and the corresponding
accessor functions (mimicking the CPU_* macros from sched.h).

4ff8c001ce unix: add Fstatat on Linux for all GOOSes 
Looks like it's enough to just add wrappers pointing to the
corresponding SYS_FSTATAT{,64} or SYS_NEWFSTATAT syscall. Add a test to
verify that assumption which checks that the returned stat data matches
what is returned by Stat/Lstat.

Also add the AT_NO_AUTOMOUNT constant which may be used for the flags
parmeter.

a45f55524b unix: defer Getpagesize() to runtime 
In general, page size is not a function of the archetecture. This was
addressed in the Go standard library here:
https://go-review.googlesource.com/25051

This change simply defers to the standard library "syscall" package,
which in turn defers to the runtime. This helps in addressing golang/go#10180 and
also fixes a bug on ppc64.

Currently, we return 65536 as the page size on ppc64, but the kernel
supports 4k and 64k sizes, see here:
http://elixir.free-electrons.com/linux/v4.13/source/arch/powerpc/include/asm/page.h#L24

Now that various page size calculations are not needed, various
components are now dead code and can also be removed. This CL reverts:

31e1fafe95 unix: update Linux to v4.13 kernel and v2.26 glibc 
This change updates the Linux symbols to correspond to v4.13 of the
kernel and v2.26 of glibc. To get everything building correctly, newer
versions of the build tools are required. Instead of trying to get an
Ubuntu 17.10 docker image working, we just add Artful sources to
/etc/apt/sources.list to get a similar effect.

Now that the kernel UAPI is updated, FS_MAX_KEY_SIZE and fscrypt_key no
longer need to be manually declared, as they are now in the proper
kernel headers.
