Anatol Belski 246cb03e26 Fix event log handling in startup phase
The log header can be saved in the globals on startup. At the same
time, the log header can be changed per request. In case that
happened, wrong pointer will be free'd on shutdown. It can happen at
any point when zend_error() or similar is called at startup, like for
example in the case of the ini deprecation warnings. Thus, ZMM cannot
be used here.
