This reverts commit e3e14bb730 in an
attempt to fix issue #3292.
The problem that's addressed is very elusive:
* It cannot be reproduced reliably.
* It seems to be more prone to appear in release builds.
* It only seems to appear when two or more instruments are mixed into
one channel.
* If you solo a problematic Triple Osc it goes away.
The observations above seem to indicate that there's rather a problem
with the mixing (due to multithreading?) and that the changes made to
Triple Osc seem to trigger this deeper problem more quickly.
Change all phase related variables in Oscillator from float to double.
The parameters for the getSample methods have not been changed to double
as it should suffice to only update the phase variables with double
precision.
Most files and most of the core classes and their methods have been
renamed to match new coding style conventions:
391 files changed, 25400 insertions(+), 25598 deletions(-)
Furthermore splitted some files where model and view classes were
declared or implemented together in the same file.
Should be tested thoroughly as I might have missed renaming some virtual
methods or SIGNAL/SLOT parameters.
