[PATCH 0/4] test-tool: split up "read-cache" tool

When the sparse index topic was being discussed I suggested that the t/helper/read-cache.c tool was getting to the point of doing too many things and should be split up.

Since that series has landed on master here's that suggestion again in the form of patches on top of master. The 4/4 patch is a "while I was at it" addition of an extra perf test for index refreshing.
