lib/subprocess: add callback feature to the subprocess library
For the libflashrom-compatible interface I'm working on, I needed the
ability to process data from the flashrom subprocess in a callback
function.
This adds a new type of subprocess_target, TARGET_CALLBACK, which can
read and write to/from a callback function.
