Add pipewire plugin It is quite similar to the remoting plugin. It just exports the frames via pipewire instead of the builtin GStreamer pipeline. It implements the same virtual output API. Virtual outputs can be created by adding 'pipewire-output' sections to weston.ini. The generated frames can be accessed with any pipewire client. e.g. with GStreamer: gst-launch-1.0 pipewiresrc ! video/x-raw,format=BGRx ! ...

build: separate deps for int and ext libweston users We have two kinds of libweston users: internal and external. Weston, the frontend, counts as an external user, and should not have access to libweston private headers. The shell plugins are external users as well, because we intend people to be able to write them. Renderers, backends, and some plugins are internal users who will need access to private headers. Create two different Meson dependency objects, one for each kind. This makes it less likely to accidentally use a private header. Screen-share is a Weston plugin and therefore counts as an external user, but it needs the backend API to deliver input. Until we are comfortable exposing public API for that purpose, let it use internal headers. Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>

build: simplify include_directories Define common_inc which includes both public_inc and the project root directory. The project root directory will allow access to config.h and all the shared/ headers. Replacing all custom '.', '..', '../..', '../shared' etc. include paths with common_inc reduces clutter in the target definitions and enforces the common #include directive style, as e.g. including shared/ headers without the subdirectory name no longer works. Unfortunately this does not prevent one from using private libweston headers with the usual include pattern for public headers. Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
