Use dynamic stack allocation in the SILK encoder.
This makes all remaining large stack allocations use the vararray
macros.
This continues the work of 6f2d9f50 to allow compiling with
NONTHREADSAFE_PSEUDOSTACK to move the memory for large buffers
off the stack for devices where it is very limited.
It also does this for some additional large buffers used by the
PLC in the decoder.
