adf421d2ca unix: fix Signalfd function signature on linux 
The kernel raw syscall takes an additional parameter specifying
the size of the Sigset_t parameter, returns a file descriptor and sets errno.

Add a uintptr maxSize parameter, adjust the return to be (newfd int, err error).
Add the _NSIG #define and a wrapper to call with maxSize set to _C__NSIG/8 as done
in glibc/musl.

a43fa875dd unix: add missing tpacket block (sub)header 
This adds the missing tpacket_hdr_v1 struct, which is needed to read
tpacket_block_desc (hdr member, which is a union and therfore defined as
[40]byte). This doesn't modify block_desc so existing implementations
keep working.
Caveat: Although TpacketBDTS has a usec member, this will contain nsec
in case of tpacket v2 or v3.

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.

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.
