617661703a validation: make CChainState::m_mempool optional (James O'Beirne)
Pull request description:
Make `CChainState::m_mempool` optional by making it a pointer instead of a reference. This will allow a simplification to assumeutxo semantics (see https://github.com/bitcoin/bitcoin/pull/15606#pullrequestreview-692965905) and help facilitate the `-nomempool` option.

Since we now have multiple chainstate objects, only one of them is active at any given
time. An active chainstate has a mempool, but there's no point to others having one.
This change will simplify proposed assumeutxo semantics. See the discussion here:

This is part of the "UTXO Set Statistics" project in Core, which aims
to make things like "checking coin supply" faster. This stuff, and
related things in coinstats.cpp, have always been broken for Elements
in the sense that we consider only explicit outputs and we ignore
assets (so everything just gets added together to get a meaningless
total). It probably wouldn't be too hard to restrict this to only
consider policyAsset, but it's out of scope for a rebase IMO.
Also, I think this situation is fine .. I don't understand the motivation
for this or why Core is merging this when they refuse to merge an address
index .. but I guess we'll see if there are users who care about this data
and who care about it being meaningful on Elements.
Also, apologies for the big diff -- there were some mechanical changes
to deal with CT amounts, but most of the changes related to the difference
in how fees are accounted for. While I'm not thrilled with this PR, its
functional test is really good! So I think what I eventually came up with
is internally consistent.
Adds support for versionbits deployments to DeploymentEnabled,
DeploymentActiveAfter and DeploymentActiveAt. Also moves versionbitscache
from validation to deploymentstatus.
Provides DeploymentEnabled, DeploymentActiveAt, and DeploymentActiveAfter
helpers for checking the status of buried deployments. Can be overloaded
so the same syntax works for non-buried deployments, allowing future
soft forks to be changed from signalled to buried deployments without
having to touch the implementation code.
Replaces IsWitnessEnabled and IsScriptWitnessEnabled.
fa0d9211ef refactor: Remove chainparams arg from CChainState member functions (MarcoFalke)
fa38947125 refactor: Remove ::Params() global from inside CChainState member functions (MarcoFalke)
Pull request description:
The `::Params()` global is verbose and confusing. Also it makes tests a bit harder to write because they'd have to mock a global.
Fix all issues by simply using a member variable that points to the right params.
(Can be reviewed with `--word-diff-regex=.`)

Note: up to this point I still had the old "sort by UNIX timestamp"
behavior on, which may have meant that some PRs were merged out of
order (i.e. multiple merged at once, followed by no-op merges). I
turned this off, and now just use git's default topo-sort (and manually
switch between Elements merges and Bitcoin merges).
