We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This is not the most useful keyboard binding anyways, plus it will be
extremely hacky to implement it with the generic processor parameter
widgets. Therefore, we'll get rid of it and add back a more generic
keyboard binding system later.
The only major functional change is that the Track now needs to know
whether it's active or not, in order to listen to the keyboard (or not).
There are some bugs exposed/created by this, mainly:
* KeysWidget sometimes shows phantom notes. Those do not actually exist
as far as debugging has revealed and do not play in the synth.
* The keyboard can lock up Piano when rapidly pressing keys. This
appears to be a HashMap bug; I invested significant time in bugfixing
but got nowhere.
Almost all synthesizer code in Piano is removed in favor of the LibDSP
reimplementation.
This causes some issues that mainly have to do with the way Piano
currently handles talking to LibDSP. Additionally, the sampler is gone
for now and will be reintroduced with future work.
This is the first step in transitioning Piano to a full LibDSP backend.
For now, the delay effect is replaced with a (mostly identical)
implementation in LibDSP.
The new ProcessorParameterSlider attaches to a LibDSP::Processor's
range parameter (LibDSP::ProcessorRangeParameter) and changes it
automatically. It also has the ability to update an external GUI::Label.
This is used for the three delay parameters and it will become useful
for auto-generating UI for Processors.
This patch implements a couple of enhancements to the synthesizer
engine:
* Each track has a volume control.
* The input and tooltips for all controls are improved.
* The noise channel is pitched, which allows for basic drum synthesis.

(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
