8c95537698 sio_oss.c: Disallow tiny fragment sizes, as they may overload 
the system. And as sndiod runs with increased priority, it would
consume all the cpu and could in turn hang the system.

c25d86c7db sio_oss.c: if the requrested block size is a power of two 
make the oss block size calculation return the requested value.

4f56ff6181 In sio_oss_revents() use the fifo_samples counter returned 
by SNDCTL_DSP_CURRENT_{I,O}PTR to determine the device current
position. Besides being simpler than using the absolute position,
this fixes hangs in record-only mode.

c5daeee294 On OSS/FreeBSD, set poll(2) threshold to 1 byte, so that it returs 
POLLIN/POLLOUT whenever read/write can be called without blocking. By
default OSS use 1 block of threshold.

db20298468 Use the SNDCTL_DSP_SETTRIGGER interface to start/stop the device, this 
allows the "onmove" callback to be called whenever the DMA actually
starts (and not on the first write). This also removes the need for
sio_osee_setpar() call every time the device is stopped.

9be2c65600 Allow programs using OSS/FreeBSD backend to select the buffer size. 
According to kernel sources, SNDCTL_DSP_POLICY ioctl doesn't seem to
always set play and rec buffer sizes to the same value.  That's why we
use the SNDCTL_DSP_SETFRAGMENT ioctl instead.

a282420a49 In OSS/FreeBSD sio_setpar(), validate the encoding, ensuring we

4d6d7700a4 Make sio_getpar() on OSS/FreeBSD return the device block size/count 
instead of saved ones. Fixes busy loops caused by poll(2) returning
POLLOUT after the program has filled its play buffer.

7ddb1a5fe5 Don't rely on the resampling code to calculate the number of samples 
to process, as it may produce one extra sample (to handle accumulation
of fractional samples), which would cause access to one sample past
the end of the buffer and crash aucat. Fix this by limiting the number
of samples processed to a single block.

Found by and help from Michael W. Bombardieri <mb at ii.net>. Thanks.

00ffc8f5ab Add resamp_getcnt() routine to calculate the exact number of samples 
that would be consumed and produced by the sampler rate converter. Use
it to avoid partial samples that are not properly handled. Fixes
last samples of certain files causing aucat to abort.

028bb6e60d When resampling, use the exact resampling factor instead of the ration 
between input and output block sizes.  This was inherited from sndion,
but is not required for files because they are continuous streams of
samples and do not need to be split in blocks of equal duration.

This change makes playback/recording rate match exactly the requested
sample rate.

padding.
