Changes
* Changed the default MBEDTLS_ECP_WINDOW_SIZE from 2 to 3.
The correlation between this define and RSA decryption performance has
changed lately due to security hardening.
To fix the performance degradation when using default values the
window was increased from 2 to 3.
* mbedtls_mpi_exp_mod and code that uses it, notably RSA and DHM operations,
have changed their speed/memory compromise as part of a proactive security
improvement. The new default value of MBEDTLS_MPI_WINDOW_SIZE roughly
preserves the current speed, at the expense of increasing memory
consumption.
