Merge #18410: Docs: Improve commenting for coins.cpp|h

c205979031ff4e8e32a5f05bae813405f233fccd [docs] Improve commenting in coins.cpp|h (John Newbery)

Pull request description:

  - Add full commenting for spentness / DIRTYness / FRESHness and which combinations are valid
  - Remove the 'pruned' terminology, which doesn't make sense since per-txout chainstate db was merged (#10195).
  - Rename `potential_overwrite` to `possible_overwrite` to standardize terminology (there were previously examples of both, which made searching the codebase difficult).
  - Make other minor improvements to the comments

    Re-ACK 21fa0a4 per `git diff 98bee55 21fa0a4` the only change since my previous review is the following code commenting diff in `src/coins.cpp::L177-179`;  rebuilt/ran unit tests anyway as a sanity check on the unit test changes.

fe8c18ca77 Merge #10574: Remove includes in .cpp files for things the corresponding .h file already included
a720b92 Remove includes in .cpp files for things the corresponding .h file already included (practicalswift)

Pull request description:

  Remove includes in .cpp files for things the corresponding .h file already included.

  Example case:
  * `addrdb.cpp` includes `addrdb.h` and `fs.h`
  * `addrdb.h` includes `fs.h`

  Then remove the direct inclusion of `fs.h` in `addrman.cpp` and rely on the indirect inclusion of `fs.h` via the included `addrdb.h`.

  In line with the header include guideline (see #10575).

Merge #11353: Small refactor of CCoinsViewCache::BatchWrite()
5b9748f97 Small refactor of CCoinsViewCache::BatchWrite() (Dan Raviv)

Pull request description:

  `std::unordered_map::erase( const_iterator pos )` returns an iterator to the element following the removed one. Use that to optimize (probably minor-performance-wise, and definitely code-structure-wise) the implementation of `CCoinsViewCache::BatchWrite()`.

6984c98882 Merge #10645: Use nullptr (C++11) instead of zero (0) as the null pointer constant
36d326e8b Use nullptr instead of zero (0) as the null pointer constant (practicalswift)

Pull request description:

  Use `nullptr` instead of zero (0) as the null pointer constant.

  The road towards `nullptr` (C++11) is split into two PRs:
  * `NULL` → `nullptr` is handled in PR #10483 (scripted)
  * `0` → `nullptr` is handled in PR #10645 (manual, this PR)

  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

14470f9aa6 ModifyNewCoins saves database lookups
When processing a new transaction, in addition to spending the Coins of its txin's it creates a new Coins for its outputs.  The existing ModifyCoins function will first make sure this Coins does not already exist.  It can not exist due to BIP 30, but because of that the lookup can't be cached and always has to go to the database.  Since we are creating the coins to match the new tx anyway, there is no point in checking if they exist first anyway.  However this should not be used for coinbase tx's in order to preserve the historical behavior of overwriting the two existing duplicate tx pairs.

058b08c147 Do not keep fully spent but unwritten CCoins entries cached.
Instead of storing CCoins entries directly in CCoinsMap, store a CCoinsCacheEntry
which additionally keeps track of whether a particular entry is:
* dirty: potentially different from its parent view.
* fresh: the parent view is known to not have a non-pruned version.

This allows us to skip non-dirty cache entries when pushing batches of changes up,
and to remove CCoins entries about transactions that are fully spent before the
parent cache learns about them.

c9d1a81ce7 Get rid of CCoinsView's SetCoins and SetBestBlock.
All direct modifications are now done through ModifyCoins, and BatchWrite is
used for pushing batches of queued modifications up, so we don't need the
low-level SetCoins and SetBestBlock anymore in the top-level CCoinsView class.

f28aec014e Use ModifyCoins instead of mutable GetCoins.
Replace the mutable non-copying GetCoins method with a ModifyCoins, which
returns an encapsulated iterator, so we can keep track of concurrent
modifications (as iterators can be invalidated by those) and run cleanup
code after a modification is finished.

This also removes the overloading of the 'GetCoins' name.

629d75faac Combine CCoinsViewCache's HaveCoins and const GetCoins into AccessCoins.
The efficient version of CCoinsViewCache::GetCoins only works for known-to-exist
cache entries, requiring a separate HaveCoins call beforehand. This is
inefficient as both perform a hashtable lookup.

Replace the non-mutable GetCoins with AccessCoins, which returns a potentially-NULL
pointer. This also decreases the overloading of GetCoins.

Also replace some copying (inefficient) GetCoins calls with equivalent AccessCoins,
decreasing the copying.
