fix buffer, chunk and http_chunk API * remove unused structs and functions (buffer_array, read_buffer) * change return type from int to void for many functions, as the return value (indicating error/success) was never checked, and the function would only fail on programming errors and not on invalid input; changed functions to use force_assert instead of returning an error. * all "len" parameters now are the real size of the memory to be read. the length of strings is given always without the terminating 0. * the "buffer" struct still counts the terminating 0 in ->used, provide buffer_string_length() to get the length of a string in a buffer. unset config "strings" have used == 0, which is used in some places to distinguish unset values from "" (empty string) values. * most buffer usages should now use it as string container. * optimise some buffer copying by "moving" data to other buffers * use (u)intmax_t for generic int-to-string functions * remove unused enum values: UNUSED_CHUNK, ENCODING_UNSET * converted BUFFER_APPEND_SLASH to inline function (no macro feature needed) * refactor: create chunkqueue_steal: moving (partial) chunks into another queue * http_chunk: added separate function to terminate chunked body instead of magic handling in http_chunk_append_mem(). http_chunk_append_* now handle empty chunks, and never terminate the chunked body.
