Static task creation on Linux target had issues with insufficient stack
memory allocation. Type of `StackType_t` is `unsigned long` and hence
it must be considered during stack memory allocation.
Fix ensures proper working of simple HTTP server example.
Because this is the 'simple' server example, it is probably where users will start out to understand the HTTP Server API; and also where they might come if they are having problems.
So I think it is useful to explain to users what to do if they see "httpd_parse: parse_block: request URI/header too long", which can easily happen if they submit a POST from an HTML form (for example). That certainly would have helped me!
