cf57365e7c Check hashes_shown[] whenever calling mark_hash directly.
Not really needed right now (because those algorithms to have a single digest per salt), but this can change in the future

33a043ec63 Refactored internal use of esalt from sync with number of salts to sync with number of digests
This enables a true N esalts per salt feature which is required for WPA/WPA2 handling
In case we need that for a future algorithm, just make sure to have a unique value in digest in hash parser.

dad03e394d Fixed two major problems
1) SIMD code for all attack-mode

Macro vector_accessible() was not refactored and missing completely.
Had to rename variables rules_cnt, combs_cnt and bfs_cnt into il_cnt which was a good thing anyway as with new SIMD code they all act in the same way.

2) SIMD code for attack-mode 0

With new SIMD code, apply_rules_vect() has to return u32 not u32x.
This has massive impact on all *_a0 kernels.

I've rewritten most of them. Deep testing using test.sh is still required.

Some kernel need more fixes:

- Some are kind of completely incompatible like m10400 but they still use old check_* includes, we should get rid of them as they are no longer neccessary as we have simd.c
- Some have a chance but require additional effort like m11500. We can use commented out "#define NEW_SIMD_CODE" to find them

This change can have negative impact on -a0 performance for device that require vectorization. That is mostly CPU devices. New GPU's are all scalar, so they wont get hurt by this.
This change also proofes that there's no way to efficiently vectorize kernel rules with new SIMD code, but it enables the addition of the rule functions like @ that we were missing for some long time. This is a TODO.

62bed36638 Add verification of checksum for -m 13100
This avoid collisions by arc4'ing all data then hmac-md5
when valid ASN1 structures headers are found.
Performance should not be impacted.

223ab0b3db Cosmetic change -m 13100
Removed commented part (the commented part was there to implement full last arc4'ing + hmac-md5)
We will see if some people find collision. In this case we will add this last check
