From: Neeraj Singh <neerajsi@xxxxxxxxxxxxx>
Preparation for adding bulk-fsync to the bulk-checkin.c infrastructure.
* Rename 'state' variable to 'bulk_checkin_state', since we will later
be adding 'bulk_fsync_objdir'. This also makes the variable easier to
find in the debugger, since the name is more unique.
* Move the 'plugged' data member of 'bulk_checkin_state' into a separate
static variable. Doing this avoids resetting the variable in
finish_bulk_checkin when zeroing the 'bulk_checkin_state'. As-is, we
seem to unintentionally disable the plugging functionality the first
time a new packfile must be created due to packfile size limits. While
disabling the plugging state only results in suboptimal behavior for
the current code, it would be fatal for the bulk-fsync functionality
later in this patch series.
