I'm not sure this is much prettier than the last, but contracting
"fl_core" to "c", as Neil suggested is a bit easier on the eyes.

I also added a few small helpers and converted several users over to
them. That reduces the size of the per-fs conversion patches later in
the series. I played with some others too, but they were too awkward
or not frequently used enough to make it worthwhile.

Many thanks to Chuck and Neil for the earlier R-b's and comments. I've
dropped those for now since this set is a bit different from the last.

I'd like to get this into linux-next soon and we can see about merging
it for v6.9, unless anyone has major objections.

Thanks!

Changes in v3:
- Rename "flc_core" fields in file_lock and file_lease to "c"
- new helpers: locks_wake_up, for_each_file_lock, and lock_is_{unlock,read,write}
- Link to v2: https://lore.kernel.org/r/20240125-flsplit-v2-0-7485322b62c7@kernel.org

Changes in v2:
- renamed file_lock_core fields to have "flc_" prefix
- used macros to more easily do the change piecemeal
- broke up patches into per-subsystem ones
- Link to v1: https://lore.kernel.org/r/20240116-flsplit-v1-0-c9d0f4370a5d@kernel.org
