The custom IO handlers will be extended to not just do serial line emulation (generally over Bluetooth rfcomm), but do BLE too. BLE does not look like a serial protocol at all, it's packet-based, and we may have to add specific routines to indicate which GATT endpoints to use etc. But like the traditional custom serial code, we want to do the actual IO not from within libdivecomputer, but from the user of the library (because the BLE support will require things like the Qt Connectivity layer - and we do not want libdivecomputer to have to link against something like Qt). So this renames 'custom_serial' to 'custom_io', and instead names the individual member function pointers 'serial_*' to make it clear that those members are for serial communication. It also adds new placeholders for packet_open/close/read/write. Note that while these may look similar to the serial counter-parts, they are not the same or even necessarily mutually exclusive. It is possible the the caller fills in one or the other (or both), and they would be used independently. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
