linux-user: Add support for translation of statx() syscall

Implement support for translation of system call statx().

The implementation is based on "best effort" approach: if host
is capable of executing statx(), host statx() is used. If not,
the implementation includes invoking a more mature system call
fstatat() on the host side to achieve as close as possible
functionality.

Support for statx() in kernel and glibc was, however, introduced
at different points of time (the difference is more than a year):

- kernel: Linux 4.11 (30 April 2017)
- glibc: glibc 2.28 (1 Aug 2018)

In this patch, the availability of statx() support is established
via __NR_statx (if it is defined, statx() is considered available).
This coincedes with statx() introduction in kernel.

However, the structure statx definition may not be available in
any header for hosts with glibc older than 2.28 (and it is, by
design, to be defined in one of glibc headers), even though the
full statx() functionality may be supported in kernel. Hence, a
structure "target_statx" is defined in this patch, to remove that
dependency on glibc headers, and to use statx() functionality as
soon as the host kernel is capable of supporting it. Such statx
structure definition is used for both target and host structures
statx (of course, this doesn't mean the endian arrangement is
the same on target and host - the endian conversion is done in
all necessary cases).

When we have updated kernel headers to 5.2-rc1 we have introduced
new syscall numbers that can be not supported by older kernels
and fail with ENOSYS while the guest emulation succeeded before
because the syscalls were emulated with ipc().

This patch fixes the problem by using ipc() if the new syscall
returns ENOSYS.

components for each of the file-related time

linux-user: Pass through nanosecond timestamp components for stat syscalls

Since Linux 2.6 the stat syscalls have mostly supported nanosecond
components for each of the file-related timestamps.

QEMU user mode emulation currently does not pass through the nanosecond
portion of the timestamp, even when the host system fills in the value.
This results in a mismatch when run on subsecond resolution filesystems
such as ext4 or XFS.

An example of this leading to inconsistency is cross-debootstraping a
full desktop root filesystem of Debian Buster. Recent versions of
fontconfig store the full timestamp (instead of just the second portion)
of the directory in its per-directory cache file, and checks this against
the directory to see if the cache is up-to-date. With QEMU user mode
emulation, the timestamp stored is incorrect, and upon booting the rootfs
natively, fontconfig discovers the mismatch, and proceeds to rebuild the
cache on the comparatively slow machine (low-power ARM vs x86). This
stalls the first attempt to open whatever application that incorporates
fontconfig.

This patch renames the "unused" padding trailing each timestamp element
to its nanosecond counterpart name if such an element exists in the
kernel sources for the given platform. Not all do. Then have the syscall
wrapper fill in the nanosecond portion if the host supports it, as
specified by the _POSIX_C_SOURCE and _XOPEN_SOURCE feature macros.

Recent versions of glibc only use stat64 and newfstatat syscalls on
32-bit and 64-bit platforms respectively. The changes in this patch
were tested by directly calling the stat, stat64 and newfstatat syscalls
directly, in addition to the glibc wrapper, on arm and aarch64 little
endian targets.

linux-user: Add support for SIOC<G|S>IFPFLAGS ioctls for all targets

Add support for getting and setting extended private flags of a
network device via SIOCSIFPFLAGS and SIOCGIFPFLAGS ioctls.

The ioctl numeric values are platform-independent and determined by
the file include/uapi/linux/sockios.h in Linux kernel source code:

#define SIOCSIFPFLAGS 0x8934
#define SIOCGIFPFLAGS 0x8935

These ioctls get (or set) the field ifr_flags of type short in the
structure ifreq. Such functionality is achieved in QEMU by using
MK_STRUCT() and MK_PTR() macros with an appropriate argument, as
it was done for existing similar cases.

determined by following files in Linux kernel source tree:

arch/sparc/include/uapi/asm/sockios.h:#define SIOCSPGRP 0x8902

target/alpha: Fix user-only floating-point exceptions

Record the software fp control register, as set by the
osf_setsysinfo syscall. Add those masked exceptions
to fpcr_exc_enable.

target/alpha: Fix user-only floating-point exceptions

Record the software fp control register, as set by the
osf_setsysinfo syscall. Add those masked exceptions
to fpcr_exc_enable. Do not raise a signal for masked
fp exceptions.

target/xtensa: zero overhead loops rework/helpers split

- change xtensa zero overhead loops implementation to avoid invalidation
of TBs corresponding to previous loop body when a new loop is
encountered;
- extract helper function groups from op_helper.c and move them into
separate source files: exc_helper.c (exception helpers), win_helper.c
(windowed registers helpers), fpu_helper.c (floating point helpers),
mmu_helper.c (memory management helpers) and dbg_helper.c (native debug
helpers).

RISC-V Updates for 3.2, Part 2

This patch set contains a handful of Michael's CSR-related cleanups,
which should allow us to proceed with more outstanding bug fixes that
depend on them.

Additionally, there is a patch that turns on USB. This works for me
when the kernel has the appropriate drivers (which will soon be in
defconfig) and I pass

-device usb-ehci
-drive id=my_usb_disk,file=usbdisk.img,if=none,format=raw
-device usb-storage,drive=my_usb_disk

to QEMU.
