The settimeofday syscall accepts a tz argument indicating the desired
timezone to the kernel. QEMU previously ignored any argument provided
by the target program & always passed NULL to the kernel. Instead,
translate the argument & pass along the data userland provided.
Although this argument is described by the settimeofday man page as
obsolete, it is used by systemd as of version 213.

target_sigevent struct
Use the public sigset_t instead of the glibc specific internal
__sigset_t in _syscall.
Calculate the sigevent pad size is calculated in similar way as kernel
does it instead of using glibc internal field _pad.
This is needed for building with musl libc.

Implement the capget and capset syscalls. This is useful because

Glibc when built for newer kernels assumes that the sendmmsg syscall is
available. Without it, dns resolution simply fails to work.
Wrap the syscall with existing infrastructure so that we don't have a host
dependency on sendmmsg.
To avoid locking the same area of guest memory twice (which will break if
DEBUG_REMAP is defined) we pull the lock/unlock part of do_sendrecvmsg()
out into its own function so the actual implementation can be shared.

Some targets use a stat64 structure for the stat64 syscall while others
use a stat structure. SPARC64 used the wrong kind.
Instead of extending the conditional compilation in syscall.c, now a
macro TARGET_HAS_STRUCT_STAT64 is defined whenever a target has a
target_stat64.

Some syscall handlers have special code for ARM enabled that we don't
need on AArch64. Exclude AArch64 in those cases. In other places we
can share struct definitions with other targets or have to provide our
own.
With this patch applied, most syscall definitions in linux-user should
be sound for AArch64.

The epoll emulation uses data structures without packing them, so the
compiler might choose to add padding inside.
This patch makes the most offending one (target_epoll_event) a packed
structure to make sure we don't pad it by accident. ARM would pad it,
so declare the padding mandatory for ARM targets.
This fixes i386-on-ARM epoll emulation for me.

OpenRISC uses the asm-generic versions of target_stat and
target_stat64, but it was incorrectly using the x86/ARM/etc version
due to a misplaced defined(TARGET_OPENRISC). The previously unused
OpenRISC section of the ifdef ladder also defined an incorrect
target_stat and omitted the target_stat64 definition. Fix
target_stat, provide target_stat64, and add a comment noting that
these are the asm-generic versions for the benefit of future ports.

In case when TARGET_ABI_BITS == 32 && HOST_LONG_BITS == 64, the last
byte of the target dirent structure (aka d_type byte) was never copied
from the host dirent structure, thus breaking everything that relies
on valid d_type value, e.g. glob(3).

with size_t, not int, even though the ioctl implementations themselves
read and write integers). Since commit 354a0008 we now have an
ioctl wrapper definition for BLKBSZGET and so on an x86-64-to-x86-64
linux-user binary we were triggering the mismatch warning in
syscall_init().

Quite a number of uid/gid related syscalls are only defined on systems
with USE_UID16 defined. This is apperently based on the idea that these
system calls would never be called on non-UID16 systems. Make these
syscalls available for all architectures that define them.
drop alpha hack to support selected UID16 syscalls. MIPS and PowerPC
were also defined as UID16, to get uid/gid syscalls available, drop
this error as well.
Change QEMU to reflect this.
