- rename from "libsndio" to "sndio"
- remove support for "frame tick" synchronization; nothing uses it
- as with many other sndio backends, the audio device block size is the
buffer-write-size the application wants and there are 2 blocks per
device buffer
- if SDL will resample, increase the audio block and buffer size by
the same ratio, so that device latency (or how much *time* the
application has between write()s to not let the buffer underrun) does
not change
- allow applications to disable conversions
tested with almost every port that uses this code (exceptions being some
games that require non-free game data) on a device most likely to be
affected by the changes (azalia(4) that only does 44.1 or 48 kHz s16)
unoverriding conversion disabling exposes brokenness in a few other
ports, those will be fixed soon
Includes OpenBSD fixes and cleanups.
Other changes that concern us:
* Now gets correct keyboard state when starting up on X11
* Improved X11 fullscreen support, works better with KDE
Various improvements, including OpenBSD native audio.
* Fix audio device path. This has caused audio not to work without the
esd flavor before, many people (including me) had link to /dev/dsp because
of linux emulation programs and haven't noticed the problem.
* Fix OSS audio.
* Sync libtool patches
* Properly include @SYSTEM_LIBS@ in sdl-config to ensure proper linking
of SDL applications.
flavor, being the default one (fetching distfile from an external site).
- Isolate esd as a separate flavor from oss -- a combination with either
"sun" or "oss" is possible.
