Merge #17887: bug-fix macos: give free bytes to F_PREALLOCATE
75163f4729c10c40d2843da28a8c79ab89193f6a bug-fix macos: give free bytes to F_PREALLOCATE (Karl-Johan Alm)
Pull request description:
The macos manpage for `fcntl` (for `F_PEOFPOSMODE`) states:
> Allocate from the physical end of file. In this case, fst_length indicates the number of newly allocated bytes desired.
This would result in the rev files being essentially pre-allocating 2x their necessary size (this is the case for block files as well, but these are flushed down to their right sizes every time) as they would pre-allocate `pos + length` **free** bytes, rather than allocating `length` bytes after `pos`, as expected.
Fixes #17827.
