Running TTS and encoders with multiple threads is causing problems on Windows
since introduction of the feature (FS#12106, FS#11994). The current
implementation also makes wrong assumptions (having multiple threads talk to
the SAPI script doesn't make it run faster since it's still one thread
responsible for creation).
Completely remove multithreading support for that for now -- a different
implementation is necessary.

C99-ify variables to keep them localized
Use sum of absolute differences instead of sum of squared differences for
autocorrelation which should reach the same conclusion and avoid 64-bit
multiplication.

Mostly for the sake of reducing latency for audio servicing where other service
routines can take a long time to complete, leading to occasional drops of a
few samples, especially in recording, where they are fairly frequent.
One mystery that remains is GPIOA IRQ being interrupted causes strange
undefined instruction exceptions, most easily produced on my Fuze V2 with a
scrollwheel. Making GPIOA the top ISR for now, thus not interruptible, cures it.
SVC mode is used during the actual calls. Hopefully the SVC stack size is
sufficient. Prologue and epilogue code only uses the IRQ stack and is large
enough.
Any routine code that should not be interrupted should disable IRQ itself from
here on in.

When using a global variable from a DLL with MSVC special handling is necessary
to avoid going through additional redirection.

Instead of calling the lame executable use libmp3lame directly. As result, this
simplifies the prerequisites for creating voice clips for Archos devices to
putting the library in the system's search path (Windows: put libmp3lame.dll in
the search path or the same folder RockboxUtility.exe is located in. Linux:
install the library using your systems package manager) and configuration.
This creates a notable encoding speedup on Windows (around factor 6 on my test
setup) and a small speedup on Linux (around factor 1.2).
The implemenatation currently has the following limitations:
- Only enabled on Windows and Linux. On OS X installing the correct dylib is a
bit nontrivial, so using the old command line based method is still in use
for now.
- The encoder parameters are currently hardcoded to use the same values the
build system uses.
