cf2ef786 build: require boost for bench (Cory Fields)

Check that pre-segwit activation, unnecessary witnesses won't cause
a txid to be permanently rejected.

C_INCLUDE_PATH and CPLUS_INCLUDE_PATH work globally as though -isystem was used
for each invocation.

Since that changes the build results, force a rebuild of x86 depends by adding
the value to $HOST_ID_SALT.

Moves the IsStandard check to happen after the premature-witness check,
so that adding a witness to a transaction can't prevent mempool acceptance.

Note that this doesn't address the broader category of potential mempool DoS
issues that affect transactions after segwit activation.

fa6ad569 [travis] Update SDK_URL (MarcoFalke)

- guard PKG_PROG_PKG_CONFIG with an m4_ifdef. If not building for windows,
  require it
- add nops as necessary in case the ifdef reduces the if/then to nothing
- AC_SUBST some missing _LIBS. These were split out over time, but not all were
  properly substituted. They continued to work if pkg-config is installed
  because it does the AC_SUBST itself

The non-pkg-config case can't use pkg-config to check the version.

Also, make sure that the check is properly guarded in the case of missing
pkg-config macros.

efd1d833 doc: Mention dbcache increase in release notes (Wladimir J. van der Laan)
32cab912 Bump `-dbcache` default to 300MiB (Wladimir J. van der Laan)

Also cap the allocation for the leveldb-specific cache for the UTXO set
to 8MiB.
This avoids that the extra cache memory goes to the much less effective
leveldb cache instead of our application-level cache.

20f3cd75 wallet: Revert input selection post-pruning (Wladimir J. van der Laan)

4fbdc436 Revert "net: Avoid duplicate getheaders requests." PR #8054 (Gregory Maxwell)

This reverts commit f93c2a1b.

This can cause synchronization to get stuck.

36f1b9df Tests: Increase sync_blocks() timeouts in pruning.py (Suhas Daftuar)

This reverts PR #4906, "Coinselection prunes extraneous inputs from
ApproximateBestSubset".

Apparently the previous behavior of slightly over-estimating the set of
inputs was useful in cleaning up UTXOs.
