If the mempool is not completely full, treat the difference between
the maximum size and the actual usage as available for the coin cache.
This also changes the early flush trigger from (usage > 0.9 * space)
to (usage > 0.9 * space && usage > space - 100MB). This means we're not
permanently leaving 10% of the space unused when the space is large.

deec83f init: Get rid of fServer flag (Wladimir J. van der Laan)
16ca0bf init: Try to aquire datadir lock before and after daemonization (Wladimir J. van der Laan)
0cc8b6b init: Split up AppInit2 into multiple phases (Wladimir J. van der Laan)
Before daemonization, just probe the data directory lock and print an
early error message if possible.
After daemonization get the data directory lock again and hold on to it until exit
This creates a slight window for a race condition to happen, however this condition is harmless: it
will at most make us exit without printing a message to console.

f5b960b Move nTimeBestReceived updating into net processing code (Matt Corallo)
d8670fb Move all calls to CheckBlockIndex out of net-processing logic (Matt Corallo)
d6ea737 Remove network state wipe from UnloadBlockIndex. (Matt Corallo)
fc0c24f Move MarkBlockAsReceived out of ProcessNewMessage (Matt Corallo)
65f35eb Move FlushStateToDisk call out of ProcessMessages::TX into ATMP (Matt Corallo)
UnloadBlockIndex is only used during init if we end up reindexing
to clear our block state so that we can start over. However, at
that time no connections have been brought up as CConnman hasn't
been started yet, so all of the network processing state logic is
empty when its called.
Additionally, the initialization of the recentRejects set is moved
to InitPeerLogic.

0278fb5 Remove duplicate nBlocksEstimate cmp (we already checked IsIBD()) (Matt Corallo)
87e7d72 Make validationinterface.UpdatedBlockTip more verbose (Matt Corallo)
This adds a new CValidationInterface subclass, defined in main.h,
to receive notifications of UpdatedBlockTip and use that to push
blocks to peers, instead of doing it directly from
ActivateBestChain.
Simplified version of #8278. Assumes that every OS that (a) is supported
by Bitcoin Core (b) supports daemonization has the `daemon()` function
in its C library.
- Removes the fallback path for operating systems that support
daemonization but not `daemon()`. This prevents never-exercised code from
ending up in the repository (see discussion here:
https://github.com/bitcoin/bitcoin/pull/8278#issuecomment-242704745).
- Removes the windows-specific path. Windows doesn't support `daemon()`,
so it don't support daemonization there, automatically.
Original code by Matthew King, adapted by Wladimir van der Laan.
This was broken by 63cafa6329.
Note that while this fixes the settings, it doesn't fix the actual usage of
-maxuploadtarget completely, as there is currently a bug in the
nOptimisticBytesWritten accounting that causes a delayed response if the target
is reached. That bug will be addressed separately.
In the case of (for example) an already-running bitcoind, the shutdown sequence
begins before CConnman has been created, leading to a null-pointer dereference
when g_connman->Stop() is called.
Instead, Just let the CConnman dtor take care of stopping.
CConnman then passes the current best height into CNode at creation time.
This way CConnman/CNode have no dependency on main for height, and the signals
only move in one direction.
This also helps to prevent identity leakage a tiny bit. Before this change, an
attacker could theoretically make 2 connections on different interfaces. They
would connect fully on one, and only establish the initial connection on the
other. Once they receive a new block, they would relay it to your first
connection, and immediately commence the version handshake on the second. Since
the new block height is reflected immediately, they could attempt to learn
whether the two connections were correlated.
This is, of course, incredibly unlikely to work due to the small timings
involved and receipt from other senders. But it doesn't hurt to lock-in
nBestHeight at the time of connection, rather than letting the remote choose
the time.
waitfornewblock waits until a new block is received, or the timeout expires, then
returns the current block height/hash.
waitforblock waits for a specific blockhash, or until the timeout expires, then
returns the current block height/hash. If the target blockhash is the current
tip, it will return immediately.
waitforblockheight waits until the tip has reached a certain height or higher,
then returns the current height and hash.
waitforblockheight is used to avoid polling in the rpc tests.

Also cap the allocation for the leveldb-specific cache for the UTXO set
to 8MiB.
This avoids that the extra cache memory goes to the much less effective
leveldb cache instead of our application-level cache.
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.
Putting the build date in the executable is a practice that has no place
in these days, now that deterministic building is increasingly common.
Continues #7732 which did this for the GUI.
Move the version reporting to Wallet::Verify, before starting
verification of the wallet.
This removes the dependency of init on a specific wallet database
library.
A further, trivial step towards resolving #7965.
Rather than allowing CNetAddr/CService/CSubNet to launch DNS queries, require
that addresses are already resolved.
This greatly simplifies async resolve logic, and makes it harder to
accidentally leak DNS queries.
Split out methods to every module, apart from 'help' and 'stop' which
are implemented in rpcserver.cpp itself.
- This makes it easier to add or remove RPC commands - no longer everything that includes
rpcserver.h has to be rebuilt when there's a change there.
- Cleans up `rpc/server.h` by getting rid of the huge cluttered list of function definitions.
- Removes most of the bitcoin-specific code from rpcserver.cpp and .h.
Continues #7307 for the non-wallet.
The "feefilter" p2p message is used to inform other nodes of your mempool min fee which is the feerate that any new transaction must meet to be accepted to your mempool. This will allow them to filter invs to you according to this feerate.
