We use the sha256 hash for the block index for performance reasons, which is recorded for later use.
CheckProofOfWork() uses the scrypt hash which is discarded after a block is accepted.
While it is technically feasible to verify the PoW, doing so takes several minutes as it
requires recomputing every PoW hash during every Litecoin startup.
We opt instead to simply trust the data that is on your local disk.
Thanks to Lolcust and ArtForz for the Zeitgeist patch. This fixes an issue where a
51% attack can change difficulty at will. Go back the full period unless it's the
first retarget after genesis.
Thanks to pooler for the overflow fix.
nMaxInbound might very well be 0 or -1, if the user prefers to keep
a small number of maxconnections.
Note: nMaxInbound of -1 means that the user set maxconnections
to 8 or less, but we still want to keep an additional slot for
the feeler connection.

We normally prefer to connect to peers offering the relevant services.
If we're not connected to enough peers with relevant services, we
probably don't know about them and could use dnsseed's help.

Only allow skipping relevant services until there are four outbound
connections up.
This avoids quickly filling up with peers lacking the relevant
services when addrman has few or none of them.

Base64 contains '/', and the '/' character in credentials is problematic
for AuthServiceProxy which represents the RPC endpoint as an URI with
user and password embedded.
Closes#8399.
