libirecovery-a814b04770dc83774cd705d2fc8993f24e504a01.tar.bz2
Implemented irecv_get_status() to return current iphone usb "state".
Implemented irecv_send_buffer() to upload a buffer to the device load address. Implemented irecv_send_file() to read a file into memory and pass the buffer into irecv_send_buffer()
