English grammar dictates that these bullet points should be capitalized.
This also makes the capitalization style consistent with the rest of the
document, e.g. the "Decision Making Process" section.
Safemode is almost useless as is-- it only triggers in limited
cases most of which aren't even concerning. There have been
several proposals to remove it. But as a simpler, safer, and
more flexible first case, simply deactivate it by default.
Anyone who wants it can re-enable and know what they've signed up for.

055d95f [wallet] return correct error code from resendwallettransaction (John Newbery)
Pull request description:
New code in #10995 uses `RPC_INVALID_REQUEST`. According to the comment in rpc/protocol.h:
```
// RPC_INVALID_REQUEST is internally mapped to HTTP_BAD_REQUEST (400).
// It should not be used for application-layer errors.
```
Change the returned error code to `RPC_WALLET_ERROR`
#11000 will need to be updated to test for the correct error code.

Pull request description:
With this, the amounts returned in `decoderawtransaction` will be padded to 8 digits like anywhere else in the API.
This is accomplished by using `ValueFromAmount` in `TxToUniv`, instead of `FormatMoney` which it currently (mistakingly) uses. The `FormatMoney` function is only for debugging/logging use!
To avoid dependency issues, `ValueFromAmount` is moved to `core_write.cpp`, where it also fits better. I don't move `AmountFromValue` to `core_read.cpp` at the same time, as this would have more impact due to the RPCError dependency there.
(n.b.: large number of changed files is solely due to the util_tests JSONs needing update)

This is necessary because core_write has to write amounts in
TxToUniv, and mistakingly uses FormatMoney for that
(which is only for debugging).
We don't move AmountFromValue at the same time, as
this is more challenging due to the RPCError depencency
there.

1de73f4 Disconnect network service bits 6 and 8 until Aug 1, 2018 (Matt Corallo)
Pull request description:
Immediately disconnect peers that use service bits 6 and 8 until August 1st, 2018
These bits have been used as a flag to indicate that a node is running incompatible
consensus rules instead of changing the network magic, so we're stuck disconnecting
based on the service bits, at least for a while.
Staying connected to nodes on other networks only prevents both sides from reaching consensus quickly, wastes network resources on both sides, etc.
Didn't add constants to protocol.h as the code there notes that "service bits should be allocated via the BIP process".

The reason for the uninitialized `nLocalServices` is that `CConnman::Start(...)` is not called
by the tests, and hence the initialization normally performed by `CConnman::Start(...)` is
not done.
This commit adds a method `Init(const Options& connOptions)` which is called by both the
constructor and `CConnman::Start(...)`. This method initializes `nLocalServices` and the other
relevant values from the supplied `Options` object.

This fixes a few cases where we should be treating a restart-after-
coinsviewdb-reset identically to a just-reset-coinsviewdb.
Thanks to @morcos for identifying the bug.
This more clearly uses fReindex vs fReset to make sure we're not
clearing our coinsdb needlessly when restarting after a reindex.
It also makes it so that restarting after shutting down mid-reindex
isn't treates specially at all during txdb loading code, as it
shouldn't be.
This resolves a possible-assert-on-shutdown race introduced in
1f668b6468 when early shutdown
occurs.
Previously this was not done to avoid any cases where the
threadGroup might not exit due to a blocking thread, but at this
point the threadGroup isn't used all that much, plus Qt already
does this, and its good to keep their init/shutdown consistent.
For those curious, the threadGroup is only used in a few places:
* Its used to run the CCheckQueues in script validation, but these
use the boost mutex/condition variable primitives, so they
respect the interrupt pretty trivially.
* Its used for the import thread, which should exit rather quickly
as mostly it just calls LoadExternalBlockFile, which has an
interruption_point right before each block loaded.
* Its used in the scheduler thread, which is only used for:
* validationinterface has an effectively-dummy reference to it.
* wallet compaction, which should not last long
* addr/banlist dumping from CConnman, which should also be fast
