The method offsetInBlock assumes the block actually is the one this
transaction is in, the assert helps making sure that this assumption
isn't broken, prodicing unusable results.
Move the MutableTransactionSignatureChecker class out of the header and
thereby remove the need to include transaction.h in the header.
This checker was never used in any app, just in the unit tests.
This also fixes includes around.
Especially seen in the block-validation tests, we sometimes delete
the validation engine while some other threads are still doing stuff
with the not surprising effect that we may cause crashes or asserts
to get hit.
This change makes us wait instead.
Summary:
CMerkleBlock::CMerkleBlock called IsRelevantAndUpdate() on each transaction
in order, which (due to the outpoint-adding feature) assumes a topological
order of transactions in order to work correctly. If an outpoint of
interest were created later in a block than when gets spent, then it would
be added into the bloom filter too late, and thus that spending transaction
would get missed.
This changes CMerkleBlock::CMerkleBlock to scan all outputs first, then
make a second loop to scan all inputs. This requires breaking up the
IsRelevantAndUpdate() function into two parts. The original
IsRelevantAndUpdate() functionality remains fully intact however, as it
gets called from mempool-related code (mempool has topological order) and
tests.
Note that vMatchedTxn.push_back is moved into the second loop so that index
i keeps ascending order, in case that is somehow relevant. (the tests at
least do check this)
A two-loop construction like this will very slightly increase the false
positive rate.

The API throws when the directories already exist, which is quite
unexpected.
This now changes the code to silently ignore these issues in the
knowledge that the immediately following opening of files will
fail with a nice error message.
I got some UTXOs to test and now got some blocks filled
there, which proves the concept.
Its a bit slow to start (1 -> 20 tx are hardcoded) which was not an
issue if you can call generate() to mine, may be useful to adjust
for scalenet.
Yet, the basis works.
