eglinfo: feature parity with glxinfo and wglinfo
It's the weekend, time for another batch of eglinfo changes. :D
This changes the output format of eglinfo slightly, now the printed extension lists are comma-separated rather than space-separated. (GL_EXT_foo, GL_EXT_bar
instead of GL_EXT_foo GL_EXT_bar
)
