Check for paused processing state in various places, so that startup
playback works properly, and resume playback at seek offset works
properly and doesn't hang the player.

The samples available function returns a signed integer, so it can
apparently return negative on error, and the DSP was incorrectly casting
this to an unsigned type, and thus attempting to buffer an inordinate
number of samples and crashing.

Upstream functions which return empty chunks on error do not return nil,
so the caller should check for an empty duration instead.

And disable it by default in new installations, otherwise leave the
setting alone. The disablement setting is shared with the engine
setting, so the default should not really change anything, except for
new installs.
Also, the time/pitch shifting dialog disables itself and displays an
obvious notice button, which opens the Rubber Band settings.

Sample block merging code should not be duplicated across the DSPs that
require it, but instead should be a common function. Also added some
optimizations to the Float32 converter function, to bypass conversion if
the audio format needs no conversion.

Attempt to completely fill the input buffer of the Rubber Band library
between each call to the process function, instead of processing in
as small an increment as the source node provides. May reduce processing
power required.

Audio Chunks now have full timestamp accounting, including DSP playback
speed ratio for the one DSP that can change play ratio, Rubber Band.
Inputs which support looping and actually reporting the absolute play
position now do so.
