Jon Shallow a7f53b4d6b coap_debug.h: Allow <syslog.h> to be included before and after <coap3/coap.h> ...

The syslog LOG_ definitions are defined in <syslog.h> and can be defined in
coap_debug.h (wrapped by a HAVE_SYSLOG_H wrapper to prevent duplicaton).

However, the coding order of
  include <coap3/coap.h>
  include <stdio.h
works, but
  include <stdio.h
  include <coap3/coap.h>
but fails if the application build environment does not define HAVE_SYSLOG_H
(as is the case of the examples in the examples/ directory).

The former "just" happens to work as the values of the variables are the same.

This fix is to remove the coap_log_t enum and replace it by simple #define
if LOG_ALERT etc. is not already defined.

Make coap_log_t int to remove Visual Studio compile warnings.
