[PATCH wayland 1/4] scanner: use c99 initializers for the wl_interface * array

[Daniel Stone]

Hi Emil,
Discussing the scanner symbol visibility patch made me realise that I
never replied here.

This would definitely need fixing before we could do anything.

But that being said, my worry is that we don't actually control the
compilation environment for the scanner output. Scanner output
currently compiles with '-pedantic -ansi -Wall -Wextra' (at least,
when inline is defined). This patch changes that requirement, and I
worry that - like previous discussions on changing scanner output -
that upgrading Wayland would lead to people hitting compilation
failures.

Cheers,
Daniel
