Merge branch 'ns/batch-fsync'
Introduce a filesystem-dependent mechanism to optimize the way the bits for many loose object files are ensured to hit the disk platter. * ns/batch-fsync: core.fsyncmethod: performance tests for batch mode t/perf: add iteration setup mechanism to perf-lib core.fsyncmethod: tests for batch mode test-lib-functions: add parsing helpers for ls-files and ls-tree core.fsync: use batch mode and sync loose objects by default on Windows unpack-objects: use the bulk-checkin infrastructure update-index: use the bulk-checkin infrastructure builtin/add: add ODB transaction around add_files_to_cache cache-tree: use ODB transaction around writing a tree core.fsyncmethod: batched disk flushes for loose-objects bulk-checkin: rebrand plug/unplug APIs as 'odb transactions' bulk-checkin: rename 'state' variable and separate 'plugged' boolean
