lib: remove CONSTCOND comment

Since 2021-01-31, lint doesn't need it anymore for the common pattern of
'do ... while (0)'.

Allow calling puffs_mount(3) before puffs_daemon(3)

puffs_daemon(3) creates a pipe before forking, and the parent process
waits for the child to either complete puffs_mount(3) or fail. If a
user calls puffs_daemon(3) after puffs_mount(3), the function
deadlocks. While this error-reporting functionality is really a nice
thing to have, deadlocking is not great. If the filesystem has already
been mounted, puffs_mount(3) should just daemonize the process and
return.

This became an issue because fuse_daemonize(3) in FUSE API had no such
requirement and some FUSE filesystems in the wild suffered deadlocks.

Use size_t in place of voff_t in puffs_setrootinfo(3)

Chuck Silvers pointed out that voff_t was also supposed to be
kernel-only. The correct type to use in userland would be off_t, but
since changing vsize_t to either voff_t or off_t is an ABI change on
32-bit platforms, we use size_t knowing that it is technically
incorrect.

Avoid using register_t or vsize_t in <puffs.h>

<puffs.h> is a user-space header, and should not use any of
kernel-only types. It's not reasonable to require user-land
filesystems to #define _KERNTYPES.

Do not warn about relative path because of trailing slash

libpuffs calls realpath() to obtain an absolute path to use for mounting.
If the obtained path is different from the one given by the caller, a
warning is issued. This included the situation where the path passed by
the caller just have trailing slashes, a situation where we just want them
to be striped without a warning.

There seems to be no fdiscard FUSE operation at the moment, hence that

* support extended attributes
* bump major due to structure growth
* add some spare space
* remove ABI sillyness
Support extended attributes.
Fix multiple non compliances in our Linux-like extattr API, and make it
public so that it can be used.
Improve a bit listxattr(2). It attemps to list both system and user
extended attributes, and it faled if calling user did not have privilege
for reading system EA. Now we just lise user EA and skip system EA in
reading them is not allowed.
Fix bug introduced in previous commuit: Do not vrele() a vnode we did not
obtained.
Improve UFS1 extended attributes usability
- autocreate attribute backing file for new attributes
- autoload attributes when issuing extattrctl start
- when autoloading attributes, do not display garbage warning when looking
up entries that got ENOENT
Add a flag to VOP_LISTEXTATTR(9) so that the vnode interface can tell the
filesystem in which format extended attribute shall be listed.
There are currently two formats:
- NUL-terminated strings, used for listxattr(2), this is the default.
- one byte length-pprefixed, non NUL-terminated strings, used for
  extattr_list_file(2), which is obtanined by setting the
  EXTATTR_LIST_PREFIXLEN flag to VOP_LISTEXTATTR(9)
This approach avoid the need for converting the list back and forth, except
in libperfuse, since FUSE uses NUL-terminated strings, and the kernel may
have requested EXTATTR_LIST_PREFIXLEN.

Implement lazy contexts for file systems using puffs_mainloop().
Previously each request was executed on its own callcontext and
switched to every time the request was being processed.  Now requests
borrow the mainloop context and switch only if/when they yield.
This takes two context switches away from a file system request
bringing down the typical amounts 2->0 (e.g. dtfs) and 4->2 (e.g.
psshfs).

The interfaces for manually executing requests changed a bit:
puffs_dispatch_create() and puffs_dispatch_exec() must now be used.
They are not tested, as nothing in-tree wants them and I doubt
anyone else is really interested in them either.

Also do some misc code cleanup related to execution contexts.  The
"work-in-progress checkpoint" committed over a year ago was starting
to look slightly weed-infested.

Part 3/n of extensive changes to message handling:

Get rid of the original puffs_req(3) framework and use puffs_framebuf(3)
instead for file system requests.  It has the advantage of being
suitable for transporting a distributed message passing protocol
and therefore us being able to run the file system server on any
host.

Ok, puffs is not quite here yet: libpuffs needs to grow request
routing support and the message contents need to be munged into a
host independent format.  Saying which format would be telling,
but it might begin with an X, end in an L and have the 13th character
in the middle.  Keep an eye out for the sequels: Parts 3+m/n.

Add some very initial support for a threading worker model as an
alternative to the (vastly superior ;) continuation model.  This
is very preliminary stuff and not compiled by default (which it
even won't do without some other patches I cannot commit yet).

The raison d'commit of the patch is a snippet which ensures proper
in-order dispatching of all operations, including those which don't
require a response.  Previously many of them would be dispatched
simultaneosly, e.g. fsync and reclaim on the same node, which
obviously isn't all that nice for correct operation.

Part 1/n of some pretty extensive changes to how the kernel module
interacts with the userspace file server:

  * since the kernel-user communication is not purely request-response
    anymore (hasn't been since 2006), try to rename some "request" to
    "message".  more similar mangling will take place in the future.

  * completely rework how messages are allocated.  previously most of
    them were borrowed from the stack (originally *all* of them),
    but now always allocate dynamically.  this makes the structure
    of the code much cleaner.  also makes it possible to fix a
    locking order violation.  it enables plenty of future enhancements.

  * start generalizing the transport interface to be independent of puffs

  * move transport interface to read/write instead of ioctl.  the
    old one had legacy design problems, and besides, ioctl's suck.
    implement a very generic version for now; this will be
    worked on later hopefully some day reaching "highly optimized".

  * implement libpuffs support behind existing library request
    interfaces.  this will change eventually (I hate those interfaces)

Make puffs_framebuf better suited from environments with multiple sources:

* in addition add/remove, allow enable/disable, which can be used
  to control events for descriptors without having to remove all the
  data associated with them
* add directsend/receive, which can be used to pass the same buffer
  from the caller to read/writeframe and back again
* add flags to enqueue functions and allow urgent buffers to be
  processed as the next PDU

Reflect kernel changes for supplying root node information in mount
instead of puffs_start().  Get completely rid of puffs_start(), as
everything it used to do is now handled by the mount routine.
Introduce an optional pre-mount call puffs_setrootinfo() for setting
non-default root node information.  As the old puffs_mount() is
now virtually useless, say byebye to it and rename the old
puffs_domount() to puffs_mount(), but add a root cookie parameter
to compensate for the late puffs_start().

Instead of keeping on adding parameters to puffs_mount(), make it
only take the bare essentials, which currently means removing
"maxreqlen" from the argument list (all current callers I'm aware
of set it as 0 anyway).  Introduce puffs_init(), which provides a
context for setting various parameters and puffs_domount(), which
can be used to mount the file system.  Keep puffs_mount() as a
shortcut for the above two for simple file systems.

add libpuffs - the userspace programming interface for puffs

This work was initially started and completed for Google SoC 2005
and tweaked to work a bit better in the past few weeks.  While
being far from complete, it is functional enough to be able and
stable to host a fairly general-purpose in-memory file system in
userspace.  Even so, puffs should be considered experimental and
no binary compatibility for interfaces or crash-freedom or zero
security implications should be relied upon just yet.

The GSoC project was mentored by William Studenmund and the final
review for the code was done by Christos.
