Fixed division by zero exception in ngx_hash_init(). The ngx_hash_init() function did not expect call with zero elements count, which caused FPE error on configs with an empty "types" block in http context and "types_hash_max_size" > 10000. Example configuration to reproduce: events { } http { types_hash_max_size 10001; types {} server {} }
