The low level serial and IrDA functions are modified to: - Use the libdivecomputer namespace prefix. - Return a more detailed status code instead of the zero on success and negative on error return value. This will allow to return more fine-grained error codes. - The read and write functions have an additional output parameter to return the actual number of bytes transferred. Since these functions are not atomic, some data might still be transferred successfully if an error occurs. The dive computer backends are updated to use the new api.
