Fixes#2224 and lightningnetwork/lnd#9053.
Depending on the version of Bitcoin Core, the "warnings" field in the
response to getnetworkinfo is either a single string value or an array
of strings.
We can easily parse those two variants with a custom type that
implements an UnmarshalJSON method.
The block files may be open when deleteFile is called. This resulted in
files not being deleted and erroring out on windows. Properly closing
the files closing the files avoids this error.
This change lets us test that we don't attempt to delete open files with
unit tests. On Windows this behavior is not allowed which results in an
error but on linux and osx it's allowed. To better test Windows
compatibilty adding this explicit check in is useful.

A cleaner fix is to set the startTime in the server Start() function
which is where the server is actually started.

Fix the btcctl uptime command by moving the setting of startupTime
Fixes#2199.
Previous to this fix the keytype was only interpreted as a single byte,
even though BIP-0174 states it is to be parsed as a CompactSize/VarInt.
ReconsiderBlock reconsiders the validity of the block for the passed
in blockhash. The behavior of the function mimics that of Bitcoin Core.
The invalid status of the block nodes are reset and if the chaintip that
is being reconsidered has more cumulative work, then we'll validate the
blocks and reorganize to it. If the cumulative work is lesser than the
current active chain tip, then nothing else will be done.
reorganizeChain() used to handle the following:
1: That the blocknodes being disconnected/connected indeed to connect
properly without errors.
2: Perform the actual disconnect/connect of the blocknodes.
The functionality of 1, the validation that the disconnects/connects can
happen without errors are now refactored out into
verifyReorganizationValidity.
This is an effort made so that ReconsiderBlock() can call
verifyReorganizationValidity and set the block status of the
reconsidered chain and return nil even when an error returns as it's ok
to get an error when reconsidering an invalid branch.
This is to mitigate CVE-2017-12842. Along the way, also error when
deserializing transactions that have the witness marker flag set
but have no witnesses. This matches Bitcoin Core's behaviour initially
introduced here https://github.com/bitcoin/bitcoin/pull/14039. Allowing
such transactions is benign, but this makes sure that our parsing code
matches Core's exactly.
This exposes publicly the ability to decode arbitrary-length bech32
strings and return the bech32 version that was used in the encoding. It
provides the underlying functionality for both DecodeNoLimit and
DecodeGeneric.
InvalidateBlock() invalidates a given block and marks all its
descendents as invalid as well. The active chain tip changes if the
invalidated block is part of the best chain.
