Avoid 'using' in headers.
Remove unused m4 files, add or update others as necessary.
Disable examples broken by blockchain refactor.
Fix unused parameter warning.
Create md readme, regen boilerplate, update authors and news.
Make pretty.
Fix cruft and errors in config/make/pc. Add comments and version requirements.
remove both fetch_block_transaction_hashes and replace with a single
fetch_block_transaction_indexes (by block hash).

This enforces people to use the block hash instead of height which is safer.
use prefix iterator in for loop as per guide.
import no longer takes a height parameter.
Remove comment exclusion of build-excluded broken examples.
Clear redundant README in favor of markdown version.
Fix tests, forgot that boost doesn't install package config.
Cosmetic line reorder.
Punctuation.
