[PATCH v2 0/3] Adding a performance framework

This is a reroll of the original RFC at

  http://thread.gmane.org/gmane.comp.version-control.git/187127

Basically, a perf framework that uses little perf scripts written in the style we already use in the test suite.

As Junio pointed out, the line between GIT_BUILD_DIR and GIT_TEST_INSTALLED was not very clear cut or well adhered to, so I threw out the overrides for the former. This also made GIT-TEST-OPTIONS moot.

There are no other changes, though I did a rebase on current next.

Thomas Rast (3):
  Move the user-facing test library to test-lib-functions.sh
  Introduce a performance testing framework
  Add a performance test for git-grep
