Zhang Junyang cdac59beda Implement a new set of physical page APIs 2024-12-27 12:12:51 +08:00
Zhang Junyang c9a37ccab1 Renaming concepts around pages and frames 
This commit renames `Frame` -> `UntypedFrame` and `Page` -> `Frame`.
So do other concepts in the following list:
 - `Segment` -> `UntypedSegment`,
 - `ContPages` -> `Segment`,
 - `DynPage` -> `AnyFrame`,
 - `PageMeta` -> `FrameMeta`,
 - `FrameMeta` -> `UntypedMeta`.

This commit also re-organized the source in the `mm/page` and `mm/frame`
module to accommodate the changes.
