d298ff8b62 During IBD, prune as much as possible until we get close to where we will eventually keep blocks (Luke Dashjr)
Pull request description:
This should reduce pruning flushes even more, speeding up IBD with pruning on systems that have a sufficient dbcache.
Assumes 1 MB per block between tip and best header chain. Simply adds this to the buffer pruning is trying to leave available, which results in pruning almost everything up until we get close to where we need to be keeping blocks.

The src/node/ directory contains code that needs to access node state
(state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar
classes).
Code in src/node/ is meant to be segregated from code in
src/wallet/ and src/qt/, to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the src/node/,
src/wallet/, or src/qt/ directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/ classes.
This directory is at the moment
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
