since these are only local path resolves, the do and wait are
technically not needed. also remove any other tmp strings
and use the vpath string resolving feature to avoid
printfs/strjoins/cats etc. etc. as well.
also remember to remove old name string from evas shm code - it worked
for me. i guess i was lucky and it happened to be NULL thus free was
fine.
This reverts commit 2037474dc0.
This causes the wayland_shm engine to seg fault immediately at
startup when attempting to create shm buffers.
Please make sure when committing changes to the wayland_shm engine to
test on intel, exynos, and at least one platform without dmabuf
capabilities - or using the EVAS_WAYLAND_SHM_DISABLE_DMABUF env var
to disable dmabuf on intel or exynos.
Anyone without the time or hardware to fully test changes to wayland_shm
can submit a patch to phabricator and assign it to me so I can fully
test it before landing.

this should make the wayland shm engine safe to use from setuid
processes. it shouldnt depend on getenv of specific file paths if
setuid. vpatrh takes care of this in one central place
On session recovery the engine needs to be given new copies of the
surface, dmabuf, and shm objects to run in the new connection.
This fixes session recovery breakage introduced when we stopped recreating
the outbuf on reconfigure.
When a canvas gets hidden, we don't need to destroy & recreate the
wl_surface. We can simply attach a NULL wl_buffer to the surface which
achieves the same result. This saves us from having to always destroy
& recreate surfaces when we hide/show.

When triple buffering it's possible that we'll only need two buffers at
a time for long durations. When we finally call upon a third buffer it
hasn't been used recently enough to do a partial redraw.
By picking the oldest available buffer when multiple buffers are free we
can increase the likelihood of doing partial redraws.

We need to be creating buffers with ARGB by default so that things
like Alpha/Transparency work when toggled. If we always create with
XRGB then toggling Alpha/Transparency state fails.

Split this into two parts, one that makes the base surface, one that
calls the potential back ends.
Once the dmabuf backend is added this will allow a fallback path to
re-initialize the surface as wl_shm if dmabuf fails.
This doesn't really care what the buffers were allocated with, so
let's make this chunk of code useful to both the shm method and the
upcoming dmabuf one
As portions of this code have been derived from existing code in
Weston, we should also be including their copyright/license text to
give credit.

We're supposed to allocate a large pool at startup and use it for
resizing to save pool allocations. However, this was broken and
we ended up allocating both a large pool and a proper sized pool
every resize.
This restores correct behaviour.
Summary:
printf %m stringifies and prints errno. I've tried to remove its use
anywhere that the immediately preceding function might not set errno
or is a complicated function for which knowing errno doesn't really
give any useful information.
I've left a few of the drmMode calls because they're just wrappers
around ioctl, which legitimately sets errno.

Summary:
wl_surface.damage_buffer() takes surface damage in buffer co-ordinates.
Right now since we don't use wayland's scaling, transforms, or viewports
it's exactly the same as wl_surface.damage(). In the future if we start
using those features it's much easier to do so with damage_buffer().

This fixes a rendering issue with wayland apps. We consume all buffers then
