Bugfix
* Ensure that calling mbedtls_rsa_free() twice is safe. This happens
when some Mbed TLS library functions fail. Such a double-free was
not safe when MBEDTLS_THREADING_C was enabled on platforms where
freeing a mutex twice is not safe.
* Fix a resource leak in a bad-arguments case of mbedtls_rsa_gen_key()
when MBEDTLS_THREADING_C is enabled on platforms where initializing
a mutex allocates resources.
Default behavior changes
* In mbedtls_rsa_context objects, the ver field was formerly documented
as always 0. It is now reserved for internal purposes and may take
different values.
