Last master fails to work with non-fdo

[clopez]

Not sure if this was caused by 17cfde0 or it was a previous issue.

I'm testing with ae3e565 and wpebackend-rdk/wayland-egl and cog is currently broken unless a "-P randomstring is passed".

Simply starting cog without parameters fails with:

root@qemux86-64:~# cog http://igalia.com
(cog:2550): Cog-DEBUG: platform_setup: Platform name: (null)
(cog:2550): Cog-DEBUG: platform_setup: Platform = (nil)

(cog:2550): Cog-CRITICAL **: cog_platform_get_view_backend: assertion 'platform != NULL' failed
**
Cog:ERROR:/usr/src/debug/cog/20180514-r0/git/cog.c:301:on_create_web_view: 'error' should not be NULL
Aborted

Starting it with a random invalid platform plugin name however works

root@qemux86-64:~# cog -P nonexistent http://igalia.com
(cog:2557): Cog-DEBUG: platform_setup: Platform name: nonexistent
(cog:2557): Cog-DEBUG: platform_setup: Platform plugin: libcogplatform-nonexistent.so

(cog:2557): Cog-WARNING **: Could not load: libcogplatform-nonexistent.so (possible cause: Socket operation on non-socket).

@clopez Just want to report similar issue when building from: Igalia/meta-webkit@83b5700
wpebackend-fdo was used in my case

cog  https://people.igalia.com/clopez/wkbug/fps-counter/raf_onload.html
(cog:528): Cog-CRITICAL **: cog_platform_get_view_backend: assertion 'platform != NULL' failed
**
Cog:ERROR:/usr/src/debug/cog/20180514-r0/git/cog.c:301:on_create_web_view: 'error' should not be NULL

In my case also libWPEBackend-default.so was missing, but that's another (or mine) issue:

cog -P fdo  https://people.igalia.com/clopez/wkbug/fps-counter/raf_onload.html
xkbcommon: ERROR: couldn't find a Compose file for locale "C"
wpe: could not load the impl library. Is there any backend installed?: libWPEBackend-default.so: cannot open shared object file: No such file or directory
Wayland: Got a wl_compositor interface
Wayland: Got a wl_seat interface
Wayland: Got an xdg_shell interface
Wayland: Got a wl_shell interface
EGL initialized with version 1.4

After adding a symlink to wpebackend-fdo:

xkbcommon: ERROR: couldn't find a Compose file for locale "C"

@macpijan: About the missing libWPEBackend-default.so symlink, I have experienced that myself. We are not yet at the point where loading a platform plug-in makes the symlink unnecessary, but ideally when using a Cog platform plug-in the symlink should not be needed... I have filed #11 to track that separately.
