ncg * ipg calcualtion can overflow if signed types are used. Move
to uint32_t for the relevant values. Aligned with FreeBSD changes.
Also make sure newfs refuses to create an fs with more that 2^32-1

to find another, instead of first forward and then backward. The latter method
causes most full cgs to end up at the end of the partition. From FreeBSD.

from the range [1..UINT_MAX] initially. On inode re-use increment
and on wrap refill from the range [1..UINT_MAX-1] to avoid
assigning UINT_MAX (the original value). Zero still means uninitialized.

Avoid a tight CPU loop when no unlocked worklist items can be processed.2020-03-09T16:49:12Zmillertmillert@openbsd.org2020-03-09T16:49:12Zurn:sha1:e2086e682725f53d68e22e4ef655dc2a593916da
If process_worklist_item() is unable to process locked vnodes,
num_on_worklist will still be non-zero, preventing the loop in
softdep_process_worklist() from exiting. This can result in a
kernel hang.
To fix this, process_worklist_item() now returns non-zero if it was
able to process a worklist item (regardless of whether it matched
the mountpoint) and takes a pointer to matchcnt as a function
argument. We now break out of the loop in softdep_process_worklist()
if process_worklist_item() is unable to make progress.

Remove unused "struct proc *" argument from the following functions:2020-02-27T09:10:31Zmpimpi@openbsd.org2020-02-27T09:10:31Zurn:sha1:db7aa9821c9615b2b21dc263b8e1f99309ff4e4a
- ufs_chown() & ufs_chmod()
- ufs_reclaim()
- ext2fs_chown() & ext2fs_chmod()
- ntfs_ntget() & ntfs_ntput()
- ntfs_vgetex(), ntfs_ntlookup() & ntfs_ntlookupfile()
While here use `ap->a_p' directly when it is only required to re-enter
the VFS layer in order to help reducing the loop.

Improve small random read ffs performance:2020-01-24T13:01:29Zkurtkurt@openbsd.org2020-01-24T13:01:29Zurn:sha1:8078e9e980e81d39797c631373b889a379b68c73
Only call bread_cluster if either the previously read ffs block is
adjacent to the current block or if the current read request exceeds the
current ffs block. This effectively turns off read-ahead for random reads
that fall within one ffs block.
