Crash when (double) freeing ssl_mutexes

What steps will reproduce the problem?
1. call mg_start() with a certificate
2. stop mongoose
3. call again with NO certicate
4. stop mongoose => CRASH

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
official 3.1 on linux 2.6.38

Please provide any additional information below.

ssl_mutexes is a static and it was not reset to NULL after been freed, so 
another mg_start/stop will call again the free

#ifndef NO_SSL
  if (ssl_mutexes != NULL) {
    free(ssl_mutexes);
    ssl_mutexes = NULL; // FIX
  }
#endif // !NO_SSL

have fun :-)
