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:
