Few (mostly trivial) cleanups and fixes (#1940)
* Drop nBudgetProposalEstablishingTime

* Refactor: replace `== COutPoint()` with `.IsNull()`

* Refactor: add `operator bool()` to CMasternodePing

* Refactor: actually use `operator bool()` for CPendingDsaRequest

* Refactor: fixing code style in TrafficGraphData

* Fix some comments and whitespaces

* Drop legacy X11 code

No longer used... if it ever was used at all.

Switch nTimeLastSuccessfulStep from GetTimeMillis() to GetTime() (#1923)
This makes PS mockable. And we don't need that much of a precision here anyway.

Do not send dash-specific requests to masternodes before we are fully connected (#1882)
* Do not send dash-specific requests to masternodes before we are fully connected

Open all masternode connections via CConnman::ThreadOpenMasternodeConnections only. Queue requests and process them after some timeout.

* drop excessive `mnodeman.`

* switch from queues to maps of pending requests

* adjust few strings, add TODO for POOL_STATE_CONNECTING

* fix

* there can be only one pending dsa request per ps client

1e62969fa6 Preparations for upcoming backport of Bitcoin #8580
Instead of deriving from CTransaction, we now have a CTransactionRef member
in CTxLockCandidate. This is needed for the next backported PR #8580,
which will make CTransaction immutable.

Also use CTransactionRef in CDarkSendEntry, CDarksendBroadcastTx and
CPrivateSendServer

Also remove bogus "nVersion = this->nVersion" assignments. These were
leftovers from old times.

753b1e486b Eliminate remaining uses of g_connman in Dash-specific code. (#1635)
This monstrous change eliminates all remaining uses of
g_connman global variable in Dash-specific code.

Unlike previous changes eliminating g_connman use
that were isolated to particular modules, this one covers
multiple modules simultaneously because they are so interdependent
that change in one module was quickly spreading to others.

This is mostly invariant change that was done by
* changing all functions using g_connman to use connman argument,
* changing all functions calling these functions to use connman argument,
* repeating previous step until there's nothing to change.

After multiple iterations, this process converged to final result,
producing code that is mostly equivalent to original one, but passing
CConnman instance through arguments instead of global variable.

The only exception to equivalence of resulting code is that I had to
create overload of CMasternodeMan::CheckAndRemove() method without arguments
that does nothing just for use in CFlatDB<CMasternodeMan>::Dump() and
CFlatDB<CMasternodeMan>::Load() methods.
Normal CMasternodeMan::CheckAndRemove() overload now has argument of
CConnman& type and is used everywhere else.

The normal overload has this code in the beginning:

    if(!masternodeSync.IsMasternodeListSynced()) return;

Masternode list is not synced yet when we load "mncache.dat" file,
and we save "mncache.dat" file on shutdown, so I presume that it's OK
to use overload that does nothing in both cases.
