ALSA: fall back to nearest available buffer-size
...
The warning "samples per period does not match." never triggered.
Previously not being able to set the requested buffersize was a
fatal error.
This adds support for soundcards that only support msec.

JACK latency compensation for newly created tracks #8472

Pulseaudio: allow steam being suspended during export
...
When exporting long sessions with freewheeling, pulseaudio
may meanwhile suspend the corked audio device. The "FAIL_ON_SUSPEND"
option then prevents ardour to uncork it after export, and the
audio-backend is halted.

This potentially breaks various assumptions (e.g. no resampling,
fixed buffersize) when the stream is moved to a different device.
Then again it's pulseaudio, which is unsuitable for pro-audio to
begin with.

for the capture device before configuring the playack

Tweak ALSA nperiod setting, fallback to nearest
...
This is mainly for RME RayDAT that has a fixed buffersize of 16k:
dev_name : hw:HDSPMxc2f6c5,0
channels : 36
min_rate : 32000
max_rate : 192000
min_bufz : 16384
max_bufz : 16384
min_nper : 4
max_nper : 512
However nperiod configuration determines the effective latency
regardless.
This is similar to https://github.com/jackaudio/jack1/blob/master/drivers/alsa/alsa_driver.c#L476-L486
