Added ngx_http_set_complex_value_size_slot(). If a complex value is expected to be of type size_t, and the compiled value is constant, the constant size_t value is remembered at compile time. The value is accessed through ngx_http_complex_value_size() which either returns the remembered constant or evaluates the expression and parses it as size_t.
