    glsl: fix possible string overrun in gst_glsl_version_profile_from_string

    given a NULL-terminated string, s.
    s[i] = '\0';
    i++;
    does not guarentee that s[i] is NULL terminated and thus string operations
    could read off the end of the array.

    glshader: don't read invalid list pointers (use after free)

    gst_gl_shader_detach_unlocked already removes the list entry so attempting
to
    use the element to iterate to the next stage could read invalid data.
