Ticket 48978 - Convert slapi_log_error() to a variadic macro
Description: In order to replace the LDAPDebug() logging functions with
slapi_log_error() we need make slapi_log_error behave as the
LDAPDebug() marco does. The benefit of having the logging
function macro is that you can completely remove the presence
of error logging. This is very beneficial when investigating
a performance issue.
