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.

Fixes golang/go#14216

e825973668 unix: unify NsecToTime{spec,val}, fix for times < 1970
All the implementations of NsecToTimespec and NsecToTimeval were the
same other than types. Write a single version that uses
GOARCH/GOOS-specific setTimespec and setTimeval functions to handle the
types.

The logic in NsecToTimespec and NsecToTimeval caused times before 1970
to have a negative usec/nsec. The Linux kernel requires that usec
contain a positive number; for consistency, we do this for both
NsecToTimespec and NsecToTimeval.

Follow CL 30826 which did the same for syscall.

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:

156c5a2da4 unix: use struct pt_regs for PtraceRegs on mips
On mips, "struct user" bears no relation to the actual structure used by
PTRACE_GETREGS. The real structure is "struct pt_regs" which is declared
in asm/ptrace.h

Fixes golang/go#20338.

Update mksyscall*.pl to skip generating calls to "use".
Make build tag handling match what's used in the syscall package.
