e1913dbb58 egl-helpers: fix display init for x11
When running on gtk we need X11 platform not mesa platform.
Create separate functions for mesa and x11 so we can keep
the egl #ifdef mess local to egl-helpers.c

d755defd5d ui: input-linux: Add absolute event support
This patch adds support for absolute pointer events to the input-linux
subsystem. This support was omitted from the original input-linux patch,
however most of the code required for it is already in place.

Support for absolute events is especially useful for guests with vga
passthrough. Since they have a physical monitor, none of normal channels
for sending video output (vnc, etc) are used, meaning they also can't be
used to send absolute input events. This leaves QMP as the only option
to send absolute input into vga passthrough guests, which is not its
intended use and is not efficient.

This patch allows, for example, uinput to be used to create virtual
absolute input devices. This lets you build external systems which share
physical input devices between guests. Without absolute input
capability, such external systems can't seamlessly share pointer devices
between guests.

bd269ebc82 sockets: Limit SocketAddressLegacy to external interfaces
SocketAddressLegacy is a simple union, and simple unions are awkward:
they have their variant members wrapped in a "data" object on the
wire, and require additional indirections in C.  SocketAddress is the
equivalent flat union.  Convert all users of SocketAddressLegacy to
SocketAddress, except for existing external interfaces.

Note that checkpatch emits a few "line over 80 characters" warnings.

5229564b83 test-qga: Actually test 0xff sync bytes
Commit 62c39b3 introduced test-qga, and at face value, appears
to be testing the 'guest-sync' behavior that is recommended for
guests in sending 0xff to QGA to force the parser to reset.  But
this aspect of the test has never actually done anything: the
qmp_fd() call chain converts its string argument into QObject,
then converts that QObject back to the actual string that is
sent over the wire - and the conversion process silently drops
the 0xff byte from the string sent to QGA, thus never resetting
the QGA parser.

An upcoming patch will get rid of the wasteful round trip
through QObject, at which point the string in test-qga will be
directly sent over the wire.

But fixing qmp_fd() to actually send 0xff over the wire is not
all we have to do - the actual QMP parser loudly complains that
0xff is not valid JSON, and sends an error message _prior_ to
actually parsing the 'guest-sync' or 'guest-sync-delimited'
command.  With 'guest-sync', we cannot easily tell if this error
message is a result of our command - which is WHY we invented
the 'guest-sync-delimited' command.  So for the testsuite, fix
things to only check 0xff behavior on 'guest-sync-delimited',
and to loop until we've consumed all garbage prior to the
requested delimiter, which is compatible with the documented actions
that a real QGA client is supposed to do.

Ideally, we'd fix the QGA JSON parser to silently ignore 0xff
rather than sending an error message back, at which point we
could enhance this test for 'guest-sync' as well as for
'guest-sync-delimited'.  But for the sake of this patch, our
testing of 'guest-sync' is no worse than it was pre-patch,
because we have never been sending 0xff over the wire in the
first place.

f3fddaf60b trace: disallow more than 10 arguments per trace event
The UST trace backend can only cope with upto 10 arguments. To ensure we
don't exceed the limit when UST is not compiled in, disallow more than
10 arguments upfront.

This prevents the case where:

  commit 0fc8aec7de
  Author: Zhang Chen <zhangchen.fnst@cn.fujitsu.com>
  Date:   Tue Apr 18 10:20:20 2017 +0800

    COLO-compare: Optimize tcp compare trace event

    Optimize two trace events as one, adjust print format make
    it easy to read. rename trace_colo_compare_pkt_info_src/dst
    to trace_colo_compare_tcp_info.

regressed the fix done in

  commit 2dfe5113b1
  Author: Alex Bennée <alex.bennee@linaro.org>
  Date:   Fri Oct 28 14:25:59 2016 +0100

    net: split colo_compare_pkt_info into two trace events

    It seems there is a limit to the number of arguments a UST trace event
    can take and at 11 the previous trace command broke the build. Split the
    trace into a src pkt and dst pkt trace to fix this.

Now we get an immediate fail even when UST is disabled:

- decompress run-length encoding escape sequences
- report command parsing problems to output when debug output is enabled
- reject packet checksums that are not valid hex digits
- compute the checksum based on the packet stream, not based on the
  decoded packet

Tested with GDB and QtCreator integrated debugger on SMP QEMU instance.
