Fix makefs bootstrap after d485c77f203fb0f4cdc08dea5ff81631b51d8809

Fix makefs bootstrap after d485c77f203fb0f4cdc08dea5ff81631b51d8809

The makefs msdosfs code includes fs/msdosfs/denode.h which directly uses
struct buf from <sys/buf.h> rather than the makefs struct m_buf.
To work around this problem provide a local denode.h that includes
ffs/buf.h and defines buf as an alias for m_buf.

Remove #define _KERNEL hacks from libprocstat

Make sys/buf.h, sys/pipe.h, sys/fs/devfs/devfs*.h headers usable in
userspace, assuming that the consumer has an idea what it is for.
Unhide more material from sys/mount.h and sys/ufs/ufs/inode.h,
sys/ufs/ufs/ufsmount.h for consumption of userspace tools, with the
same caveat.

Remove unacceptable hack from usr.sbin/makefs which relied on sys/buf.h
being unusable in userspace, where it override struct buf with its own
definition. Instead, provide struct m_buf and struct m_vnode and adapt
code to use local variants.

buf: Add B_INVALONERR flag to discard data

Setting the B_INVALONERR flag before a synchronous write causes the buf
cache to forcibly invalidate contents if the write fails (BIO_ERROR).

This is intended to be used to allow layers above the buffer cache to make
more informed decisions about when discarding dirty buffers without
successful write is acceptable.

As a proof of concept, use in msdosfs to handle failures to mark the on-disk
'dirty' bit during rw mount or ro->rw update.

Extending this to other filesystems is left as future work.

I would prefer to avoid the duplication, but reluctance to doing so was
expressed in a previous review (D11197); for now copy the files and
revisit in the future.

original $NetBSD$ tag remains in each source file.

These two files were missed in r320212. Also remove a stray blank line
added in msdosfs_vfsops.c.
