* Unify parking_lot/arc_lock feature
* Move lib/common/{io,memory}/* -> lib/common/common/*
- Mmap-related items are grouped into `common::mmap` sub-module:
- `memory/src/chunked_utils.rs` -> `common/src/mmap/chunked.rs`
- `memory/src/madvise.rs` -> `common/src/mmap/advice.rs`
- `memory/src/mmap_ops.rs` -> `common/src/mmap/ops.rs`
- `memory/src/mmap_type_readonly.rs` -> `common/src/mmap/mmap_readonly.rs`
- `memory/src/mmap_type.rs` -> `common/src/mmap/mmap_rw.rs`
- Filesystem-related items are grouped into `common::fs` sub-module:
- `common/src/fs.rs` -> `common/src/fs/sync.rs`
- `io/src/file_operations.rs` -> `common/src/fs/ops.rs`
- `io/src/move_files.rs` -> `common/src/fs/move.rs`
- `io/src/safe_delete.rs` -> `common/src/fs/safe_delete.rs`
- `memory/src/checkfs.rs` -> `common/src/fs/check.rs`
- `memory/src/fadvise.rs` -> `common/src/fs/fadvise.rs`
- Rest is moved straight into `common`:
- `io/src/storage_version.rs` -> `common/src/storage_version.rs`
The old `io` and `memory` are now hollow crates that re-export items
from `common`. These hollow crates will be removed in next commits.
* Replace uses of `io` and `memory` with new paths in `common`
Since `io` and `memory` are just re-exports of `common`, these
replacements are no-op.
* Remove `io` and `memory` crates
* Use RwLock for pending changes in MmapBitSliceBufferedUpdateWrapper
* Use RwLock for pending operations in DatabaseColumnScheduledDeleteWrapper
* Use RwLock for pending updates in DatabaseColumnScheduledUpdateWrapper
* Drop alive guard before reconciliation, we don't touch files after
* Remove redundant clone
* Update comments
* introduce IsAliveLock
* add tests
* rename to mark_dead
* update gridstore comment
* Update some comments
* Add must_use attribute to lock_if_alive
* Rename mark_dead to blocking_mark_dead
* make the handle take a `Weak` reference
* make dropping explicit
* use `Mutex::lock_arc` instead
* less nesting
* clippy
