Series core.fsyncmethod: add 'batch' mode for faster fsyncing of multiple objects | expand

Commit Message

From: Neeraj Singh <neerajsi@microsoft.com>

Add test cases to exercise batch mode for:
 * 'git add'
 * 'git stash'
 * 'git update-index'
 * 'git unpack-objects'

These tests ensure that the added data winds up in the object database.

In this change we introduce a new test helper lib-unique-files.sh. The
goal of this library is to create a tree of files that have different
oids from any other files that may have been created in the current test
repo. This helps us avoid missing validation of an object being added due
to it already being in the repo.

We aren't actually issuing any fsyncs in these tests, since
GIT_TEST_FSYNC is 0, but we still exercise all of the tmp_objdir logic
in bulk-checkin.
