This patch adds HTTP/1.1 compatible web-server that can be used by other. Server supports GET, POST, and HEAD requests. On client request it will call user specified GET/POST callback. Then results will be transmitted to client.
The following restrictions exist on the POST request at the moment: * only multipart/form-data with a single file object * object will be stored to a memory area specified in image_load_addr variable
