btrfs-progs: fix csum metadata reservation and add a basic test case for it #819

Closed adam900710 closed 1 week ago

The current csum conversion is using an incorrect parameter for btrfs_start_transaction(), which is 16K times larger than the expected metadata space, thus it always fail with -ENOSPC.

Fix that first, then add a basic test case using the same populate_fs() from convert test cases, and iterate through all the support csum algorithms.

Wrong code base, would re-sent the PR.
