Add in-kernel cleaner. Move cleaning-related routines into their own file.
Document the fcntl calls better in lfs.h. Bounds-check inode numbers in
segment parsing functions. Use the in-kernel cleaner in a greedy mode
for tests in tests/fs/vfs, and add a test of the kernel cleaner.

Drop -O[01] hacks for vax; no longer necessary for patched GCC 10

PR port-vax/57646: Import major vax toolchain fix by Kalvis Duckmanton

XXXRO: GCC 12 may require hacks for a while, but it turned out that
GCC 12 should be treated differently from older versions; a lot of new
files need -O[01] flags, while some may no longer require it.

I will take a look later.

Note that these hacks are not required if Kalvis's patches for GCC 12
are applied.

Keep doc/HACKS entries for a while (will be sync with update for GCC 12).

remove GCC_NO_ADDR_OF_PACKED_MEMBER for several subdir builds
that are now handled by lfs_accessors.h internally.

add support for new GCC 9 warnings that may be too much to fix
right now. new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

Suppress spurious address-of-packed error in rump lfs too.

branches: 1.14.18; 1.14.22;
elide vax compiler bug.

Add a COMMENT describing what each component roughly does.

"make describe" prints the comment.

Requested/inspired by Vincent Schwarzer on rumpkernel-users

Change lfs from hash table to vcache.

- Change lfs_valloc() to return an inode number and version instead of
a vnode and move lfs_ialloc() and lfs_vcreate() to new lfs_init_vnode().

- Add lfs_valloc_fixed() to allocate a known inode, used by kernel
roll forward.

- Remove lfs_*ref(), these functions cannot coexist with vcache and
their commented behaviour is far away from their implementation.

- Add the cleaner lwp and blockinfo to struct ulfsmount so lfs_loadvnode()
may use hints from the cleaner.

- Remove vnode locks from ulfs_lookup() like we did with ufs_lookup().

branches: 1.11.4;
Move lfs_getpages and lfs_putpages to their own file.

branches: 1.10.2;
Merge riastradh-drm2 to HEAD.

why does rump have to have its own private build system?

branches: 1.8.2; 1.8.4;
right, why does rump have to have its own copy of all the build information?

Cleanups and hacks to make lfs userland stuff build:
- lfs_cksum.c doesn't actually need ulfs_inode.h any more.
- neither does lfs_itimes.c.
- add hacks to fsck_lfs to make it compile.
- add hacks to newfs_lfs to make it compile.
- fix warning in ulfs_quota.c when quotas are fully disabled
(as I guess is happening with the rumpity version)

XXX: This commit adds -I${NETBSDSRCDIR}/sys to the Makefiles for
XXX: fsck_lfs, newfs_lfs, and lfs_cleanerd. This needs to be cleaned
XXX: up ASAP; but I consider this less problematic in the short term
XXX: than spewing ulfs_*.h into /usr/include.

branches: 1.6.10; 1.6.20;
Globally define -Wno-pointer-sign, as it has become a pointless
exercise of "add it to every Makefile individually".

XXX: should autosynchronize with the rest of the kernel buildflags
in sys/conf/Makefile.kern.inc.

branches: 1.5.14;
Install rump libraries and utilities to the base system and remove the
private non-installed build infrastructure from sys/rump.

breakdown of commit:
* install relevant headers into /usr/include/rump
* build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern
from src/lib and install as librumpuser and librump, respectively
+ this retains the ability to test a librump build with just the
kernel sources at hand
* move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib
for general consumption, they are not kernel-space dwellers anyway
* build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs
* add chapter 3 manual pages for rump, rumpuser, ukfs and p2k
* build and install userspace kernel file system daemons if MKPUFFS=yes
is spexified
* retire fsconsole for now, it will make a comeback with an actually
implemented version shortly

Introduce RUMPs - Runnable Userspace Meta-Programs

/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment. The kernel environment is provided
by librump. Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel. Potential future rumpification targets include
for example parts of the networking stack and some device drivers.

This work was supported by Google Summer of Code 2007.
