Description

add a flag that restricts sigChecks per-input

make is so that malicious super-high-density-SigChecks transactions cannot
get into the mempool, where they would frustrate simple block assembly
algorithms.

A transaction conforming to this rule cannot (overall) exceed a density of
1 sigcheck per 36.666 bytes.
