Merge with upstream: - support for the OSTC 2 TR - add support for dive computer filtering for device discovery - various cleanups particularly to timestamp handling - remove half-duplex emulation from the I/O api * 'master' of git://github.com/libdivecomputer/libdivecomputer: Remove the half-duplex emulation from the I/O api Handle the half-duplex emulation in the vyper2 backend Use the new timer for the timestamps in the logging Use the new timer for the timeout calculations Add a high resolution timer module Add functions for converting bluetooth addresses Add support for the OSTC 2 TR Add a workaround for invalid logbook begin pointers Let the ringbuffer function handle a full ringbuffer Suppress the warning if no O2 sensors are present Integrate the connect step into the open function Implement some filter functions Add suport for applying a filter function Re-write the device discovery using the iterator api Cleanup the iterator internals

|
|
* Two different pointers to user-supplied data.
|
|
*
|
|
* The 'userdata' pointer is for the IO routines themselves,
|
|
* generally filled in by the 'xyz_open()' routine with whatever
|
|
* file descriptor etc information.
|
|
*
|
|
* The 'user_device' pointer is set when registering the
|
|
* custom IO with the download context, and has whatever
|
|
* data the downloader needs.
|
|
*
|
|
* The two are very different. The userdata is "per instance",
|
|
* and when nesting custom IO handlers, each level would
|
|
* generally have its own userdata, that would be specific
|
|
* to that particular set of IO routines.
|
|
*
|
|
* In contrast, the user_device is filled in when the
|
|
* download context is created, before open() is even called,
|
|
* and isn't specific to the IO routines, but to the download
|
|
* as a whole.
