fixes rhbz 790749 use after free of SpiceChannelEventInfo.
The lifetime of the SpiceChannelEventInfo was that of RedsStream, but it
is used by main_dispatcher_handle_channel_event after the RedsStream is
freed for the cursor and display channels. Making SCEI allocation be at
RedsStream allocation, and deallocation after the DESTROY event is
processed by core->channel_event, fixes use after free.
red_printf() takes care of adding a newline to all messages; remove the
extra newline from all messages and macros that were doubling them up.

As suggested by Alon, a simple automated test to try to find
regressions in Spice code.
To use this, compile Spice with --enable-automated-tests and
run test_display_streaming passing --automated-tests as parameter.
Some non-Linux platforms return a (caddr_t *) result for the return
value of mmap(), which is very unfortunate. Add a (void *) cast to
explicitly avoid the warning when compiling with -Werror.
For the IO vector related stuff, signed vs. unsigned comes into play so
adding a (void *) cast here is technically correct for all platforms.

Application::set_hotkeys can throw an exception if it fails parsing
the string describing the hotkeys to set. Currently this exception
is uncaught which causes spicec to terminate when the controller
tries to set invalid hotkeys. Fall back to using the default
hotkeys when the controller sends an invalid hotkeys string.
We currently hardcode this device when spicec needs to record with
alsa. However, this doesn't interact well with PulseAudio, which
means that if something is already using the recording device, spicec
won't be able to open it again.
Using "default" as the device will let spicec use the PulseAudio
alsa support and will avoid this issue.
Turns out that more recent snapshots of gcc-4.7 emit even more of these,
so the fixes which I've done before tagging the 0.10.1 release are not
enough to build warning free with the latest gcc-4.7 snapshot <sigh>.
This fixes this.

This matches what we do in client/Makefile.am to actually run the
python scripts, which is to use the python binary we find first,
preferring 'python2' over 'python'. This makes the compile work on odd
systems such as Arch Linux where the python binary is actually python3.

dc7855967f did this for the TCP_NODELAY and IP_TOS calls; we should do
it for priority as well if necessary.
We also #ifdef the setting of the low-level socket priority based on
whether we have a definition of SO_PRIORITY available. This option is
not available on Illumos/Solaris platforms; however, since we set IP_TOS
anyway it is not a big deal to omit it here.
output to send a SIGIO signal to the running program. However, we don't
handle this signal anywhere in the code, so setting the option is
unnecessary.

With Daniel P. Berrange's patches to allow use of pre-supplied fd's
as channels, we can no longer be sure that our connections are TCP
sockets, so it makes no sense to complain if a TCP/IP specific
setsockopt fails with an errno of ENOTSUP.
Note that this extends Daniel's commit 492ddb5d1d
which already added the same check to server/inputs_channel.c

The 'make syntax-check' target is used to perform various code
style sanity checks, as well as to detect certain trivial error
patterns. The target is placed in GNUmakefile, instead of Makefile.am
since it relies on GNU specific make extensions.
The actual GNUmakefile and maint.mk files are taken from the
GNULIB project, unchanged
The cfg.mk file is used to configure which of the syntax checks
are activated, to allow addition of new project specific syntax
checks, and to blacklist certain files which should not be checked
* .mailmap: Add mapping for various broken email addrs in
commit log, to stop complaints about AUTHORS file missing
entries
* GNUmakefile: define the 'syntax-check' rule
* maint.mk: definition of standard syntax checks
* cfg.mk: configuration for checks
The COPYING file already contains the license text, so the README
file need not repeat it. Instead put in a description of what
SPICE is, simple install instructions & pointers to mailing lists
and bug trackers
Since free() takes a void* parameters do not need to be cast.
The existing code here is actally fine, but it trips up the
syntax-check rule, so tweak it to an equivalent construct
which passes the syntax check
