It is INT32_MIN (negative) so that the compiler won't set the enum typedef
as unsigned int and forbid users to provide negative logging levels.

That value is used for logging domains that haven't got their level set yet,
which will tell eina_log to set it to the global logger level. We need a
special value for the unknown level.

Maybe #ifdef would fix it?
