From: Neeraj Singh <neerajsi@xxxxxxxxxxxxx>
The update-index functionality is used internally by 'git stash push' to
setup the internal stashed commit.
This change enables bulk-checkin for update-index infrastructure to
speed up adding new objects to the object database by leveraging the
pack functionality and the new bulk-fsync functionality. This mode
is enabled when passing paths to update-index via the --stdin flag,
as is done by 'git stash'.
There is some risk with this change, since under batch fsync, the object
files will not be available until the update-index is entirely complete.
This usage is unlikely, since any tool invoking update-index and
expecting to see objects would have to synchronize with the update-index
process after passing it a file path.
