Description
e.g BuildHandler?: The request 2731044503 could not be decrypted
at line 472
About 2 per hour on a N ff (3500 requests/hour) or about .06% which is a lot for something that should never happen.
either a very late reply we didn't recognize as our own IB build, or a crypto bug (in Java or i2pd), or a tagging attack.
No stat tracking this and logging isn't sufficient, so enhance those and then investigate further.

With the #1746 fix, after about 24 hours on a floodfill:
208 all-zeros reply keys
16 dup reply keys
224 total
There were no other causes, e.g. not finding our hash in any record, or decrypt failure.
The 16 dups are most likely from the same root cause as the all-zeros, i.e. uninitialized memory, fixed in i2pd 0.2.3.
So I'm declaring #1746 together with the i2pd/kovri fix as the complete fix for this ticket.
Add a subticket #1746.
