linux-user: pass correct host flags to accept4()

Flags NONBLOCK and CLOEXEC can have different values on the host and the
guest, so set correct host values before calling accept4().

This fixes several issues with accept4 system call and user-mode of QEMU.

scsi-bus: remove bogus assertion

This assertion is invalid, because get_sg_list can return an
empty sg-list even for commands that transfer no data (such
as SYNCHRONIZE CACHE).

iscsi: recognize "invalid field" ASCQ from WRITE SAME command

Some targets may return "invalid field" as the ASCQ from WRITE SAME
if they support the command only without the UNMAP field.  Recognize
that, and return ENOTSUP just like for "invalid operation code".

iscsi: ignore flushes on scsi-generic devices

Non-block SCSI devices do not support flushing, but we may still send
them requests via bdrv_flush_all.  Just ignore them.

iscsi: always query max WRITE SAME length

Max WRITE SAME length is also used when the UNMAP bit is zero, so it
should be queried even if LBPWS=0.  Same for the optimal transfer
length.

However, the write_zeroes_alignment only matters for UNMAP=1 so we
still restrict it to LBPWS=1.

PPC: openpic_kvm: Filter memory events properly

Commit 6f1834a2b exposed a bug in openpic_kvm where we don't filter
for memory events that only happen to the region we want to know
events about.

Add proper filtering, fixing the e500plat target with KVM.

bswap: Fix build on FreeBSD 10.0

FreeBSD 10.0-RELEASE has bswap16() etc. macros defined in sys/endian.h,
which leads to a conflict with our static inline definitions.

Force using the system version of the macros.
