slontis 0557d6c62b Add FIPS indicator callback.
Add a FIPS indicator callback that can be set via
OSSL_INDICATOR_set_callback(). This callback is intended to be run
whenever a non approved algorithm check has occurred and strict checking
has been disabled.The callback may be used to
log non approved algorithms. The callback is passed a type and
description string as well as the cbarg specified in OSSL_INDICATOR_set_callback.
The return value can be either 0 or 1.
A value of 0 can be used for testing purposes to force an error to occur from the algorithm
that called the callback.
