When the acquisition was stopped before a configured limit was reached,
no sample data was retrieved. This is because the api.c stop routine did
unregister the receive callback.
Pass the stop request to the receive routine instead when stop is called
while the acquisition is still running. Have sample data downloaded very
much like it's done for reached limits, and existing logic will run the
stop routine again after state was advanced to "idle".
Extend the 'state' tracking while we are here, mark sample download as
well (that was omitted in the previous implementation). Though the
omission was non-fatal. Move the release of 'dram_line' to some earlier
location (as soon as the resource is not needed any longer), before some
rather complex calls to other routines will execute.

Move the check for the capture ratio being 0..100 into the wrappers,
drop unneeded helper functions, fix incorrect variable types, minor
other consistency fixes.
This makes the code more consistent with the rest of the code-base
and also allows std_gvar_min_max_step_array() to work here.
