Part 2/n of extensive changes to request transport to/from userspace:

Rip the transport code completely out of puffs and generalize it
into an independent module which will be used for multiple purposes
in the future.  This module is called the Pass-to-Userspace
Transporter (known as "putter" among friends).

This is very much work-in-progress and one dependency with puffs
remains: the request framing format.

The device name is still /dev/puffs, but that will change soon.

Users of puffs need the following in their kernel configs now:
pseudo-device   putter

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)

Fix a race in how new cookies are checked.  Previously the checking
was done separate of inserting the cookie into the lookup structure
and without any form of interlock.  This could lead to the same
cookie pointing to two different nodes.  Remedy the race by creating
a separate "checked and ready to be inserted" cookie list which
serves as an interlock without having to hold a fs-global creation
lock.

Fix a problem introduced when I converted puffs to use newlock2:
when unmounting the file system in case of a certain timing (and
possibly some other conditions), a thread would wait on a condition
variable, while another thread broadcast the cv and immediately
proceeded to destroy it.  The result was a system frozen completely
solid shorly after the process waiting for the cv woke up.  So
introduce reference counting to synchronize destruction of the
resources in unmount.

I was able to repeat the problem only on my laptop in some special
cases, so I do not know how common it was.  Ironically, killing
the file server process violently instead of unmount() didn't have
this problem because it never entered the unmount path from two
directions.

Initial attempt at suspend/snapshot support for userspace file
servers.  This is still pretty much on the level "if it breaks ...".
It should work for single-threaded servers which handle one operation
from start to finish in one go.  Also, it does not yet totally
correctly synchronize metadata and data in some cases.  So needless
to say, it needs improvement, but it is possible that will have to
wait for some lock revampage.

Introduce flush operations, which the fs server can use to control
kernel caching.  Currently supported are only flushing the name
cache for a directory or flushing the name cache for the entire fs.

Also, get rid of PNODE_INACTIVE status, since it was racy and
essentially didn't work.  All this on top of being useless in the
first place ....

Fix a race condition that would cause the mountpoint to be cleaned
from under someone waiting for the fs server response in puffs_unmount()
if the descriptor was closed during the response wait (such as bug
leading to a crash in fs implementation unmount()).
