This commit adds support for custom stream via fopencookie function. The function allows the programmer the create his own custom stream for IO operations and hook his custom functions to it. This is a non POSIX interface defined in Standard C library and implemented according to it. The only difference is in usage of off_t instead of off64_t. Programmer can use 64 bits offset if CONFIG_FS_LARGEFILE is enabled. In that case off_t is defined as int64_t (int32_t otherwise). Field fs_fd is removed from file_struct and fs_cookie is used instead as a shared variable for file descriptor or user defined cookie. The interface will be useful for future fmemopen implementation.
