90409da6a5 Fix provider cipher reinit issue
Fixes #12405
Fixes #12377

Calling Init()/Update() and then Init()/Update() again gave a different result when using the same key and iv.
Cipher modes that were using ctx->num were not resetting this value, this includes OFB, CFB & CTR.
The fix is to reset this value during the ciphers einit() and dinit() methods.
Most ciphers go thru a generic method so one line fixes most cases.

Add test for calling EVP_EncryptInit()/EVP_EncryptUpdate() multiple times for all ciphers.
Ciphers should return the same value for both updates.
DES3-WRAP does not since it uses a random in the update.
CCM modes currently also fail on the second update (This also happens in 1_1_1).

Fix memory leak in AES_OCB cipher if EVP_EncryptInit is called multiple times.

Fix AES_SIV cipher dup_ctx and init.
Calling EVP_CIPHER_init multiple times resulted in a memory leak in the siv.
Fixing this leak also showed that the dup ctx was not working for siv mode.
Note: aes_siv_cleanup() can not be used by aes_siv_dupctx() as it clears data
that is required for the decrypt (e.g the tag).

abfc73f374 Fix EVP_DigestSign interface when used with DES CMAC
DES implementations were missing the dup/copy ctx routines
required by CMAC implementation. A regression test is added.

f5056577ba Move legacy ciphers into the legacy provider
DES, idea, seed, rc2, rc4, rc5, cast and blowfish have been moved out of the default provider.
Code shared between desx and tdes has been moved into a seperate file (cipher_tdes_common.c).
3 test recipes failed due to using app/openssl calls that used legacy ciphers.
These calls have been updated to supply both the default and legacy providers.
Fixed openssl app '-provider' memory leak
