receive-pack: purge temporary data if no command is ready to run
When pushing a hidden ref, e.g.:
$ git push origin HEAD:refs/hidden/foo
"receive-pack" will reject our request with an error message like this:
! [remote rejected] HEAD -> refs/hidden/foo (deny updating a hidden ref)
The remote side ("git-receive-pack") will not create the hidden ref as
expected, but the pack file sent by "git-send-pack" is left inside the
remote repository. I.e. the quarantine directory is not purged as it
should be.
Add a checkpoint before calling "tmp_objdir_migrate()" and after calling
the "pre-receive" hook to purge that temporary data in the quarantine
area when there is no command ready to run.
The reason we do not add the checkpoint before the "pre-receive" hook,
but after it, is that the "pre-receive" hook is called with a switch-off
"skip_broken" flag, and all commands, even broken ones, should be fed
by calling "feed_receive_hook()".
Add a new test case in t5516 as well.
