Correct. Though we don't force people (yet) to use ftdi_new(),
this will break anyway as f.e. all included example programs
demonstrate to allocate the ftdi_context structure via malloc().
-> Allocating the ftdi_context structure via malloc is much more
common than ftdi_new() and therefore not ABI compatible.

We care about ABI stability, if possible. (this one slipped my eye)
So we need a ftdi_eeprom_new(), too, right?
