The Linux accept4() syscall allows two flags only: SOCK_NONBLOCK and
SOCK_CLOEXEC, and returns -EINVAL if any other bits have been set.
Change the qemu implementation accordingly, which means we can not use
the fcntl_flags_tbl[] translation table which allows too many other
values.
Beside the correction in behaviour, this actually fixes the accept4()
emulation for hppa, mips and alpha targets for which SOCK_NONBLOCK is
different than TARGET_SOCK_NONBLOCK (aka O_NONBLOCK).
The fix can be verified with the testcase of the debian lwt package,
which hangs forever in a read() syscall without this patch.

When running a 32-bit guest on a 64-bit host, fcntl[64](F_GETFL) should
return with the TARGET_O_LARGEFILE flag set, because all 64-bit hosts
support large files unconditionally.
But on 64-bit hosts, O_LARGEFILE has the value 0, so the flag
translation can't be done with the fcntl_flags_tbl[]. Instead add the
TARGET_O_LARGEFILE flag afterwards.
Note that for 64-bit guests the compiler will optimize away this code,
since TARGET_O_LARGEFILE is zero.

virt-acpi-build.c uses warn_report. However, it doesn't include
qemu/error-report.h directly, it include qemu/error-report.h via trace.h
if we enable log trace backend. But if we disable the log trace backend
(e.g., --enable-trace-backends=nop), then virt-acpi-build.c will not
include qemu/error-report.h any more and it will lead to build errors.
Include qemu/error-report.h directly in virt-acpi-build.c to avoid the
errors.
