Not all plugins save current program in their chunk (or do not restore
it properly). We therefore have to save and restore the current program
manually.
Closes#3581879.
The code for managing programs/presets of RemotePlugin instances was
very confusing, mainly within the VstPlugin and RemoteVstPlugin class.
I therefore started to reorganize and rewrite functions.
The RemoteVstPlugin process crashed for plugins with lots of presets
as there was an overflow of the presName buffer. Chosing a bigger buffer
size fixes the problem.
Additionally initialize len variable in loadChunkFromPresetFile().
LMMS VST Support Layer has been greatly advanced as it now features
(automatable) VST controls as well as support for VST presets. This
still needs some work as it crashes with various plugins (e.g. z3ta+).
