This makes weston build again on x86_64. (It still won't build for
armhf and aarch64, because Alpine's mesa binary package is currently
stuck there, I'll look into that as well.) Detailed fixes:
1. New makedepends needed, because mesa-libwayland-egl does not exist
anymore (see Alpine's aports commits 257a236 and 4f8b36b):
wayland-libs-egl wayland-dev
This fixes configure errors:
checking for EGL_TESTS... no
configure: error: Package requirements (egl glesv2 wayland-client wayland-egl) were not met:
Package 'wayland-client', required by 'virtual:world', not found
Package 'wayland-egl', required by 'virtual:world', not found
2. Disable RDP backend, because Weston source is incompatible with
freerdp 2.0.0. This avoids compilation errors like this one:
libweston/compositor-rdp.c:193:5: error: 'SURFACE_BITS_COMMAND {aka struct _SURFACE_BITS_COMMAND}' has no member named 'bpp';
* weston: upgrade to 3.0.0
* removed no_0hz_refresh_rate patch, as this is upstreamed now
* fix regression in compositor-fbdev
* weston: compile with weston-launch enabled
The following patch is required in order to replace GNU's error()
