* Implement RemoveAskFor to indicate that we're not interested in an item anymore
When an INV item is received from the first node, the item is requested
immediately. If the same item is received from another node, an entry is
added to mapAskFor which marks the item for re-requesting in case the first
node did not respond. When the item is received from the first node,
the item was previously never removed from mapAskFor. Only the later getdata
loop in SendMessages would then gradually remove items from the map. This
is quite delayed however as the entries in mapAskFor have a timeout value.
RemoveAskFor allows to remove all entries from mapAskFor and setAskFor
when we are not interested in the item anymore (e.g. because we received
it already).

Reverts "Fix duplicate headers download in initial sync (#1589)" and all following fixes
This reverts commit 169afafd50.
* Fix duplicate initial headers sync
* Remove unnecessary LOCK in ConnectNode
FindNode already does the necessary lock
* Remove unnecessary semicolon
* Remove critical section and assert for ref counts in CNode
nRefCount is an atomic now and thus doesn't need locking anymore.
* 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

ConnectNode is meant to be private and should not be leaked outside of
CConnman. This leaking resulted in multiple problems with AddRef/Release
behaviour. We use OpenNetworkConnectio/OpenMasternodeConnection from now on
and use appropriate ForNode calls to access the CNode* instance.
This commit also changes the behaviour for already connected nodes which
are afterwards requested for a masternode connection. We don't set
fMasternode=true anymore on such nodes, which means it won't be auto
disconnected anymore from ProcessMasternodeConnections.

ignores non-tx/non-block items in PushInventory. This is fine for Bitcoin,

Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/10291, https://github.com/bitcoin/bitcoin/issues/11265
progressDelta may be 0 (or even negative according to 11265), this checks for that and prints unknown if it is, because we cannot calculate an estimate for the time remaining (would be infinite or negative).

* Pull out modaloverlay show/hide into it's own if/else block and switch to time based check
Also don't use masternodeSync.IsBlockchainSynced() for now as it won't
report the blockchain being synced before the first block (or other MN
data?) arrives. This would otherwise give the impression that sync is
being stuck.
* Fix duplicate headers download in initial sync
Now that initial block download is delayed until the headers sync is done,
it was noticed that the initial headers sync may happen multiple times in
parallel in the case new blocks are announced. This happens because for
every block in INV that is received, a getheaders message is immediately
sent out resulting in a full download of the headers chain starting from
the point of where the initial headers sync is currently at. This happens
once for each peer that announces the new block. This slows down the
initial headers sync and increases the chance of another block being
announced before it is finished, probably leading to the same behavior
as already described, slowing down the sync even more...and so on.
This commit delays sending of GETHEADERS to later in case the chain is too
far behind while a new block gets announced. Header chains will still be
downloaded multiple times, but the downloading will start much closer
to the tip of the chain, so the damage is not that bad anymore.
This ensures that we get all headers from all peers, even if any of them
is on another chain. This should avoid what happened in
https://github.com/bitcoin/bitcoin/pull/8054
which needed to be reverted later.
This fixes the Bitcoin issue https://github.com/bitcoin/bitcoin/issues/6755
* Introduce DelayGetHeadersTime chain param and fix tests
The delaying of GETHEADERS in combination with very old block times in
test cases resulted in the delaying being triggered when the first newly
mined block arrives. This results in a completely stalled sync.
This is fixed by avoiding delaying in when running tests.
* Disconnect peers which are not catched up
Peers which stop sending us headers too early are very likely peers which
did not catch up before and stalled for some reason. We should disconnect
these peers and chose another one to continue.
