* cleanup unneeded compiler variations (now builds in 7 min rather than 13 min)
* Windows:
* use VS2017 for vcpkg, VS2015 for manual build
* Linux:
* install alsa, jack, pulse, portaudio, ladspa, libsndfile for all builds
* MacOSX:
* use AppleClang
* reorder macosx build in between linux build, as macosx usually takes longer to build, allowing to make better use of build time (via pipelining)
* switch to XCode10, enabling TravisCI to support CoreAudio and CoreMidi
Instead of saving the name of the driver, it would be worth to save to pointer to the selected definition instead.
In this way, the function for deleting the driver does not need to search its name by parsing all the list, but it just needs to call the pointer into the saved definition (less code). This fix can be applied to MIDI drivers too.
I also moved the FLUID_FREE(allnames) inside the "if(allnames != NULL)" block, nothing bad should happen even by keeping that instruction outside, but actually there is no need to call the free if allnames is NULL.
In my opionion, it should be possible to simplify the code by installing the drivers with a for() cycle instead of doing tons of #ifdef...#endif.
The size of the binary code is basically the same as before, but the source lines are much less. I think that it could be done also for MIDI input drivers.
- fluid_dsound_audio_run() and fluid_win32_error() are now static functions.
- WAVEFORMATEX is not required by DirectSound during the playback. We do not need it anymore after calling ::SetFormat(), so allocating this structure dynamically inside driver structure is useless.
- Implemented support for float sample type.
- Uses an event object for handling the end of thread, it allows to combine the quit event with the later wait in milliseconds in a single block.
- Calculates the amount of milliseconds to sleep rather than sleeping always for one millisecond.
- Fix an error into a FLUID_LOG() call.
- Fix handle leak of the thread, now it is correctly closed with CloseHandle().
- ExitThread() is a nonsense in that position, since the thread is already exiting.
- Fix error when compiling with WSDK 8.1, by defining NOBITMAP, in case NOGDI macro added somewhere
