Pull request description:
Picked up by the static analyzer [Facebook Infer](http://fbinfer.com/) which I was playing around with for another research project. Just adding some asserts before dereferencing potentially null pointers.

1aa97ee08 Add savemempool RPC (Lawrence Nahum)
467cbbcbf Add return value to DumpMempool (Lawrence Nahum)
Pull request description:
Adds a simple parameterless rpc command to dump the mempool.
Rationale:
Sometimes there can be a crash for whatever reason (bug, power loss, etc) causing the mempool.dat file to not be saved.
This change allows to script/cron the rpc call to have more regular saves to the file as well as cli/ad-hoc.
This should solve issue https://github.com/bitcoin/bitcoin/issues/11086

47ba2c312 Fix currency/fee-rate unit string in the help text (Akio Nakamura)
Pull request description:
1. The RPC help text should use the constant `CURRENCY_UNIT` defined in `policy/feerate.cpp` instead of the literal `'BTC'`.
In the following 2 RPC commands, `'BTC'` is written directly in the help text.
This commit changes them to use that constant.
1) `estimatesmartfee`
2) `estimaterawfee`
2. Some RPC command use `'satoshis'` as the unit.
It should be written as `'satoshis'` instead of `'Satoshis'` in the RPC help text.
So, this commit fixes this typo in `getblocktemplate`.

ec6902d0e rpc: Push down safe mode checks (Andrew Chow)
Pull request description:
This contains most of the changes of #10563 "remove safe mode" by @achow101, but doesn't remove the safe mode yet, but put an `ObserveSafeMode()` check in (all 23) individual calls which used to have okSafeMode=false.
This cleans up the ugly "okSafeMode" flag from the dispatch tables, which is not a concern for the RPC server.

1. The RPC help text should use the constant CURRENCY_UNIT defined in
policy/feerate.cpp instead of the literal 'BTC'. In the following
2 RPC commands, 'BTC' is written directly in the help text.
1) estimatesmartfee
2) estimaterawfee
And also, for these help strings, the notation
'fee-per-kilobyte (in BTC)' is somewhat ambiguous.
To write more precisely, this commit changes to 'fee rate in BTC/kB'
with using the constant CURRENCY_UNIT.
2. Some RPC command use 'satoshis' as the unit. It should be written
as 'satoshis' instead of 'Satoshis' in the RPC help text.
So, this commit fixes this typo in getblocktemplate.
3. The phrase that '... feerate (BTC per KB) ...' is used to explain
the fee rate in the help text of following 2 RPC commands.
1) getmempoolinfo
2) fundrawtransaction
But they are different from other similar help text of the RPCs.
And also, 'KB' implies Kibibyte (2^10 byte).
To unify and to clarify, this commit changes these phrase to
'... fee rate in BTC/kB ...'.
(BTC references the constant 'CURRENCY_UNIT')
This contains most of the changes of 10563 "remove safe mode", but doesn't
remove the safe mode yet, but put an `ObserveSafeMode()` check in
individual calls with okSafeMode=false.
This cleans up the ugly "okSafeMode" flag from the dispatch tables,
which is not a concern for the RPC server.

Pull request description:
This is a followup to #10783.
- The first commit doesn't change behavior at all, just simplifies code.
- The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
- The third commit updates developer notes after the cleanup.
- The forth commit does some additional code cleanup in `getbalance`.
Followup changes that should happen in future PRs:
- [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
- [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133
- [ ] Maybe improve UniValue type error exceptions and eliminate RPCTypeCheck and RPCTypeCheckArgument functions. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133829303

90d4d89 scripted-diff: Use the C++11 keyword nullptr to denote the pointer literal instead of the macro NULL (practicalswift)
Pull request description:
Since C++11 the macro `NULL` may be:
* an integer literal with value zero, or
* a prvalue of type `std::nullptr_t`
By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.
For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf
With this patch applied there are no `NULL` macro usages left in the repo:
```
$ git grep NULL -- "*.cpp" "*.h" | egrep -v '(/univalue/|/secp256k1/|/leveldb/|_NULL|NULLDUMMY|torcontrol.*NULL|NULL cert)' | wc -l
0
```
The road towards `nullptr` (C++11) is split into two PRs:
* `NULL` → `nullptr` is handled in PR #10483 (scripted, this PR)
* `0` → `nullptr` is handled in PR #10645 (manual)

24e44c3 Don't return stale data from CCoinsViewCache::Cursor() (Russell Yanofsky)

CCoinsViewCache doesn't actually support cursor iteration returning the
current contents of the cache, so raise an error when the cursor method is
called instead of returning a cursor that iterates over stale data.
Also update the gettxoutsetinfo RPC which was relying on the old behavior to be
explicit about which view it is returning data about.

This patch makes several related changes:
* Changes the CCoinsView virtual methods (GetCoins, HaveCoins, ...)
to be COutPoint/Coin-based rather than txid/CCoins-based.
* Changes the chainstate db to a new incompatible format that is also
COutPoint/Coin based.
* Implements reconstruction code for hash_serialized_2.
* Adapts the coins_tests unit tests (thanks to Russell Yanofsky).
A side effect of the new CCoinsView model is that we can no longer
use the (unreliable) test for transaction outputs in the UTXO set
to determine whether we already have a particular transaction.
This makes the following changes:
* In undo data and the chainstate database, the transaction nVersion
field is removed from the data structures, always written as 0, and
ignored when reading.
* The definition of hash_serialized in gettxoutsetinfo is changed to no
longer incude the nVersion field. It is renamed to hash_serialized_2
to avoid confusion. The new definition also includes transaction
height and coinbase information, as this information was missing
before.
This depends on having a CHashVerifier-based undo data checksum
verifier.
Apart from changing the definition of serialized_hash, downgrading
after using this patch is supported, as no release ever used the value
of nVersion field in UTXO entries.
