46c9620 Test that unnecessary witnesses can't be used for mempool DoS (Suhas Daftuar)
bb66a11 Fix DoS vulnerability in mempool acceptance (Suhas Daftuar)
When processing a headers message that looks like a block announcement,
send peer a getheaders if the headers message won't connect.
Apply DoS points after too many consecutive unconnecting headers messages.
Moves the IsStandard check to happen after the premature-witness check,
so that adding a witness to a transaction can't prevent mempool acceptance.
Note that this doesn't address the broader category of potential mempool DoS
issues that affect transactions after segwit activation.

96806c3 Stop trimming when mapTx is empty (Pieter Wuille)
54326a6 Increase maximum orphan size to 100,000 bytes. (Gregory Maxwell)
8c99d1b Treat orphans as implicit inv for parents, discard when parents rejected. (Gregory Maxwell)
11cc143 Adds an expiration time for orphan tx. (Gregory Maxwell)
db0ffe8 This eliminates the primary leak that causes the orphan map to always grow to its maximum size. (Gregory Maxwell)
1b0bcc5 Track orphan by prev COutPoint rather than prev hash (Pieter Wuille)
6ee7f05 Allow disconnecting a netgroup with only one member in eviction. (Gregory Maxwell)
5d0ca81 Add recently accepted blocks and txn to AttemptToEvictConnection. (Gregory Maxwell)
An orphan whos parents were rejected is never going to connect, so there
is little utility in keeping it.
Orphans also helpfully tell us what we're missing, so go ahead and treat
it as INVed.
This prevents higher order orphans and other junk from
holding positions in the orphan map. Parents delayed
twenty minutes are more are unlikely to ever arrive.
The freed space will improve the orphan matching success rate for
other transactions.
As per meeting 2016-03-31

The partition checker was producing huge number of false-positives
and was disabled in 0.12.1 on the understanding it would either be
fixed in 0.13 or removed entirely from master if not.
ff2dcf2 Tests: Edit bloated varint test and add option for 'barely expensive' tests (mrbandrews)
12c5a16 Catch exceptions from non-canonical encoding and print only to log (mrbandrews)
291f8aa Continuing port of java comptool (mrbandrews)
8c9e681 Tests: Rework blockstore to avoid re-serialization. (mrbandrews)
always grow to its maximum size.
This does not go so far as to attempt to connect orphans made
connectable by a new block.
Keeping the orphan map less full helps improve the reliability
of relaying chains of transactions.
