[PATCH 0/2] object-file: fix packfile flush during transaction commit

Greetings,

This short series fixes a bug I found related to committing an ODB
transaction that contains both a loose object and "large" blob when also
configured to batch fsync loose objects. The issue can be reproduced
with the following:

	git init
	git config core.fsync loose-object
	git config core.fsyncMethod batch
	git config core.bigFileThreshold 5
	echo foo >1-foo && echo foobar >2-foobar
	git add 1-foo 2-foobar

and produces the following error:

	error: unable to write file .git/objects/pack/pack-2b7c2470289822070687e8d64186093a710eaed3.pack: No such file or directory
	fatal: unable to rename temporary file to '.git/objects/pack/pack-2b7c2470289822070687e8d64186093a710eaed3.pack'

If a "large" blob packfile is written to the transaction temporary
directory, it is unable to be flushed during transaction commit because
the underlying transaction is migrated to the main ODB before the
packfile is finalized. To avoid this, this series ensures any pending
packfile in the transaction is flushed first.

Thanks,
-Justin
