The build fails with slibtool while GNU libtool hide the issue
by silently ignoring -no-undefined.

Usually buffers to raw data are passed using void* pointers
to avoid casts and mark the buffer as raw.
Use them for read_safe and write_safe to avoid useless casts
in caller code.
As a minor convert a parameter to bool as changing the same
lines.

At red-parse-qxl.cpp#L535
if (qxl_flags & QXL_BITMAP_DIRECT) {
red->u.bitmap.data = red_get_image_data_flat(slots, group_id,
qxl->bitmap.data,
bitmap_size);
Since qxl->bitmap.data may from the guest, an attacker can make the
memslot_get_virt() check in red_get_image_data_flat() fail and
return a nullptr.
Then at red-parse-qxl.cpp#L550
if (qxl_flags & QXL_BITMAP_UNSTABLE) {
red->u.bitmap.data->flags |= SPICE_CHUNKS_FLAGS_UNSTABLE;
}
qxl_flags is assigned as qxl->bitmap.flags before, which can also be
controlled by the attacker, resulting in a NULL pointer dereference.
This dereference seems to be introduced by commit 5ac88aa7.

By default configure script detected if source directory is a
git repository and by default enable -Werror option.
This normally detects that you are developing but some build
packagers (like rpm spec with git_am option) uses git to manage
additional patches on top of source making the detection fail
and causing the build to fail.
Build packagers should not use -Werror.

See https://github.com/crossbario/autobahn-testsuite/issues/109.
Temporarily use an Ubuntu LTS distro still having Python 2, this will
make the job work for some years.
Hoping in the future to either:
- update Autobahn testsuite to Python 3;
- finding another testsuite for websockets.

Like char devices, QXL devices need to be explicily started.
For some historical reason, char devices are started when in running
state. See commi bf1d9007b. Reading that commit comments, there was a
plan to provide an API to stop/start devices invidually, but that never
happened. Whether that API would really be useful now, I wonder.
For now, just follow the char devices behaviour and start QXL devices
added when vm_running.
