f81088be70 properly implement verification using keys that have been replaced.
the basic idea is replace txIndex key with a pair (username,height).
height = -1 for the most up-to-date key, otherwise height = last block where previous key was valid.
by checking maxHeight and iterating backwards we can easily find the key to validate data from any given block number.

2c48386b4e Properly implement spam signing and checking to prevent it from been used to impersonate users.
"nobody" is an exception so default client could still send unauthenticated/anonymous spam
messages.

7e57fb2fe4 mempool uses txhash again (instead of userhash). this is needed to fix key replacement.
using userhash in mempool was a bad idea, it creates incompatibilities with merkle tree code etc.
now we are back to standard bitcoin protocol regarding tx and inv commands, possibly filter as well.
