device->mt.slot is uninitialized when we're not receiving the
evdev slot events. Always use ID 0 as we do when we generate the
touch down and motion events.
The current code works if pw->pw_shell is bash because:
"If the shell is started with the effective user (group) id not equal to
the real user (group) id, and the -p option is not supplied, these actions
are taken and the effective user id is set to the real user id."
Thus, for bash, weston's EUID == UID.
For zsh, the -p option "is enabled automatically on startup if the effective
user (group) ID is not equal to the real user (group) ID."
Thus, weston's EUID = 0, and if pw_shell is zsh, /run/user/$UID/wayland-0 is
created with euid root and not writeable by the user, causing all clients to
fail.
Fix this by always dropping privileges to the user.
Regression introduced in 636156d.
For touchpads, device->dispatch is set up when exiting
evdev_handle_device() and a potential source for a memleak.
This can't actually happen at the moment, as evdev_handle_device() won't
fail for touchpads after setting up the dispatch but prevent this from
happening in the future.
If touches are already present on the device, absinfo has the currently
active touch slot. There's a race condition where the slot may change before
we enable the fd and we thus miss out on the ABS_MT_SLOT event. It's still
slightly more correct than assuming whatever comes next is slot 0.
For Protocol B devices, mtdev merely routes the events and is not needed.
For Protocol A devices, mtdev is needed, so fail for those devices now if we
mtdev fails.
mtdev as currently used in weston is a noop. mtdev's purpose is to convert
Protocol A devices (without ABS_MT_SLOT) to Protocol B devices (slots).
For Protocol B devices mtdev merely routes the events, so checking for
slots and then using mtdev based on that adds no functionality.
Check for ABS_MT_POSITION_X/Y instead and use that to categorise a device
as MT device. mtdev will provide us with a slotted protocol for all devices.

If weston is compiled against a gl2ext.h that doesn't have the subimage
extension, but then run against a gles2 library that does provide it,
we end up disabling the glTexImage2D falback without having the subimage
code paths compiled in.
Earlier versions of gl2ext.h defined the GL_EXT_unpack_subimage tokens
without the _EXT suffix. That's been fixed and we're using the _EXT
tokens now, but just in case we're using an older, broken header, define
the _EXT tokens manually.
It is defined by the mesa #include, which is just a copy of the official
Khronos header. It's just defined in a different section than the
extension tokens. In the mean time, the extension tokens were renamed
to add a _EXT suffix (eg GL_UNPACK_ROW_LENGTH -> GL_UNPACK_ROW_LENGTH_EXT)
and we silently failed to used the subimage extension.
And check if the renderer supports the RGB565 format for wl_shm buffers
before creating the cairo surface and requesting the buffer.
It can save quite some memory with big surfaces such as desktop
backgrounds.
fbdev_output_destroy will free the memory passed into in and since we
want to pass the device name into fbdev_output_create we need to save
this to an intermediate value
