Sync with HEAD

don't check the return value of execvp() for failure to call err().
assume if it returns at all something has failed.

Use __dead

When using the top secret PUFFS_COMFD model, write out size of the
puffs kernel args before the contents.  This allows parties which
have no clue about the contents to proxy the protocol easily.

use rump_pub interface name

Sync with HEAD.

Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html

fix WARNS=4, recipe from lukem

Don't compile diagnostic code which accesses kernel symbols directly.
Will fail now since not all archs have the same symbol names.

For applications which naughtily reach over to the rump kernel
namespace without using proper interfaces, do a little namespace
compensation.

Put syspuffs_glueinit in the rump kernel namespace.

check rump_init() return value

Make syspuffs mount code supply mount_syspuffs_parseargs() like
the other mount binaries do.  Now syspuffs can be used to run all
puffs file systems as utilities.  This includes fuse file systems
and becomes interesting with the fs-utils project.  We can now do
e.g. this:

  ReFUSE ntfs-3g:
golem> echo hello | fsu_write/fsu_write ntfs-3g puffs ~/img/ntfs.img dafile
golem> fsu_cat/fsu_cat ntfs-3g puffs ~/img/ntfs.img dafile
hello
golem>

  puffs sysctlfs:
golem> fsu_ls/fsu_ls mount_sysctlfs puffs sysctl -l ddb

Same works for psshfs etcetc.

In other words, this provides total integration for "normal"
in-kernel file systems and puffs/fuse file systems on the ukfs
library level.

Note: implementation is still "first stab" and the fs-utils usage
will no doubt change.

We can actually simply use execvp() instead of /bin/sh for
exec-and-pathsearch-with-environ.
Thanks to bad for pointing this out & apb + blymn for some discussion.

exec file server via sh -c to get the benefit of PATH search.

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
