settings: add default.clock.quantum-floor property

Browse source 
Remove some of the hardcoded values (the absolute smallest buffer size,
independent on the sample rate) to a config option. Set it to the
default value of 4, like what it was before.

Change the hardcoded absolute lowest limit to 1 because anything else
does not make sense.

Enforce the quantum-floor when calculating the final graph quantum.

Fixes #3908
