Instead of forcing use of NEWLIB_LIBC, select any available complete C
library implementation. Add CONFIG_REQUIRES_FLOAT_PRINTF where needed.

Use CMSIS-DSP from its new realm. This also changes change how you
initialize FFT tables as well to use arm_cfft_init_64_f32 if you
know the FFT size in advance rather than the generic initialization
arm_cfft_init_f32.

This commit adds the test application for the CMSIS-DSP 'transform'
functions.
This test application is loosely based on the C++ test suite included
in the upstream CMSIS-DSP distribution.
