Revert "vfio: Make BARs native endian"

This reverts commit c40708176a6b52b73bec14796b7c71b882ceb102.

The resulting code wrongly assumed target and host endianness are
the same which is not always the case for PPC64.

[aw: or potentially any host supporting VFIO and TCG]

vfio: make rom read endian sensitive

All memory regions used by VFIO are LITTLE_ENDIAN and they
already take care of endiannes when accessing real device BARs
except ROM - it was broken on BE hosts.

This fixes endiannes for ROM BARs the same way as it is done
for other BARs.

This has been tested on PPC64 BE/LE host/guest in all possible
combinations including TCG.

slirp: udp: fix NULL pointer dereference because of uninitialized socket

When guest sends udp packet with source port and source addr 0,
uninitialized socket is picked up when looking for matching and already
created udp sockets, and later passed to sosendto() where NULL pointer
dereference is hit during so->slirp->vnetwork_mask.s_addr access.

Fix this by checking that the socket is not just a socket stub.

This is CVE-2014-3640.

tcx: Implement hardware acceleration

The S24/TCX framebuffer is a mildly accelerated video card with
blitter, stippler and hardware cursor.

* Solaris and NetBSD 6.x use all the hardware acceleration features
* The Xorg driver (used by Linux) can use the hardware cursor only

This patch implements hardware acceleration in both 8 bit and 24 bit
modes. It is based on the NetBSD driver sources and from tests with
Solaris.

.travis.yml: add more linux-user to the build matrix

At the same time I've grouped the $ARCH-linux-user and $ARCH-softmmu
builds together (hoping FS cache helps) and grouped all $ARCH-softmmu
only builds into one target. This reduces the build matrix slightly
which will hopefully help with build times.

.travis.yml: pre-seed sub-modules for speed

A significant portion of the build time is spent initialising all the

the build itself. By pre-seeding the .git/modules tree this will
hopefully improve things.

ohci: Split long traces to smaller ones

Recent traces rework introduced 2 tracepoints with 13 and 20
arguments. When dtrace backend is selected
(--enable-trace-backend=dtrace), compile fails as
sys/sdt.h defines DTRACE_PROBE up to DTRACE_PROBE12 only.

This splits long tracepoints.

ohci: drop computed flags from trace events

This exceeded the trace argument limit for LTTNG UST and wasn't really
needed as the flags value is stored anyway. Dropping this fixes the
compile failure for UST. It can probably be merged with the previous

main-loop.c: Handle SIGINT, SIGHUP and SIGTERM synchronously

Add the termination signals SIGINT, SIGHUP and SIGTERM to the
list of signals which we handle synchronously via a signalfd.
This avoids a race condition where if we took the SIGTERM
in the middle of qemu_shutdown_requested:
    int r = shutdown_requested;
[SIGTERM here...]
    shutdown_requested = 0;

then the setting of the shutdown_requested flag by
termsig_handler() would be lost and QEMU would fail to
shut down. This was causing 'make check' to hang occasionally.
