Joshua Ashton 3bac2e5fb8 event-loop: Handle EINTR and EAGAIN in wl_event_loop_dispatch 
This fixes an issue where it was not possible to start Gamescope under GDB on some setups.
https://github.com/ValveSoftware/gamescope/issues/743

Any signals would cause epoll_wait to return -1 and set errno to EINTR.

This also handles the EAGAIN case like the other polling loops in libwayland.

Wayland

Wayland is a project to define a protocol for a compositor to talk to its clients as well as a library implementation of the protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers.

The wayland protocol is essentially only about input handling and buffer management. The compositor receives input events and forwards them to the relevant client. The clients creates buffers and renders into them and notifies the compositor when it needs to redraw. The protocol also handles drag and drop, selections, window management and other interactions that must go through the compositor. However, the protocol does not handle rendering, which is one of the features that makes wayland so simple. All clients are expected to handle rendering themselves, typically through cairo or OpenGL.

Building the wayland libraries is fairly simple, aside from libffi, they don't have many dependencies:

$ git clone https://gitlab.freedesktop.org/wayland/wayland
$ cd wayland
$ meson build/ --prefix=PREFIX
$ ninja -C build/ install

where PREFIX is where you want to install the libraries.

See https://wayland.freedesktop.org for documentation.
