crypto: user - Prepare for CRYPTO_MAX_ALG_NAME expansion
This patch hard-codes CRYPTO_MAX_NAME in the user-space API to
64, which is the current value of CRYPTO_MAX_ALG_NAME. This patch
also replaces all remaining occurences of CRYPTO_MAX_ALG_NAME
in the user-space API with CRYPTO_MAX_NAME.
This way the user-space API will not be modified when we raise
the value of CRYPTO_MAX_ALG_NAME.
Furthermore, the code has been updated to handle names longer than
the user-space API. They will be truncated.
