This PR adds a new `lfs_fs_shrink`, which functions similarly to `lfs_fs_grow`, but supports reducing the block count. This functions first checks that none of the removed block are in use. If it is the case, it will fail.
When the block count check was added to `lfs_mount` in [littlefs-project#584][] it was mentionned to have a mount flag to disable this check in the future. Therefore, this PR: - Adds a new `flags` field to lfs_config - Defines a new `lfs_fs_flags` enum that contains these flags - Defines one flag `LFS_CFG_DISABLE_BLOCK_COUNT_CHECK` that disables the check inserted in [littlefs-project#584][] [littlefs-project#584]: littlefs-project#584

I've got some feedback on the upstream PRs, I'll apply it so that ideally when we move to 2.10.x we can go back to using upstream. |
