Starwels Fork

Adds a datadir configuration option to the linearize scripts to allow the script to use the RPC cookie instead of requiring the user to set a rpcuser and rpcpassword for the rpc server.

- The last-timestamp-encountered variable wasn’t being used properly. Rewrite code to properly allow for new blockchain files to be written when split by month.
- Properly set a blockchain file’s access and modify times.
- Add a “debug output” option to quiet certain output that might not always be desirable.
- Update the README.

Currently, the linearization scripts require input hashes to be in one endian form. Add support for byte reversal.

Github-Pull: #5494
Rebased-From: 15de949bb9

- Add a space after the fixed string prepended to file names when input or
  output file changes
- Clarify the error message when the genesis block is not found in the
  hash list (...why do we have this at all?)

Make it possible to read blocks in any order. This will be required
after headers-first (#4468), so should be merged before that.

- Read block header. For expected blocks, continue, else skip.
- For in-order blocks: copy block contents directly. Write prior
  out-of-order blocks if this connects a consecutive span.
- For out-of-order blocks, store extents of block data for later
  retrieval. Cache out-of-order blocks in memory up to 100MB
  (configurable).

Batch up to 10000 requests for a ~30x speedup.

This was typically ensured implicitly by virtue of normal bitcoind
operation.  Adding an explicit check provides a stronger guarantee, and
it is cheap to add.

Break into two steps:
* Generate hash list
* Build data file(s) from local bitcoind blocks/ directory.

This supports building one large bootstrap.dat, or multiple
smaller blocks/blkNNNNN.dat files.

linearize.py: harmonize rpcpass to rpcpassword according settings in
bitcoin.conf

Add the ability to start at a non-zero height, and allow for appending to
an existing file.
