6c71c22a44 Add "file system console", which is meant eventually to become a 
"console" to a file system, i.e. a tool for mounting any file system
image supported by rump and executing various commands on it.
Currently it's just a linear set of calls to ukfs routines and
serves mainly as a simple test program and ukfs usage example.

55a47971a5 Actually using passed parameters instead of hardcoded ones makes 
a macro work better ...

b926b490ec Add routines for pure userspace file system operation 
(i.e. no kernel involvement), namely:
* create, mknod, remove, mknod, rmdir, getdents, read, write, and link

Still obviously missing a few, but this is a start (I'm also searching
for the blessed orb of code quality, maybe someone has seen it?).

cfd4dc8f38 Wrap malloc() so that we catch the kernel arguments (namely M_ZERO) 
properly.  It's fairly amusing that this wasn't noticed until now.

c360a79960 * split userspace file system access into two separate libraries: 
+ libp2k: the interface between libpuffs and vfs/vop
  + libukfs: generic user kernel file system library, usable
	     independent of libp2k and/or puffs
* use file system name (MOUNT_XYZ) instead of vfsops pointer to
  mount file system

mostly to get the flag jungle in sync with the kernel.

643e56125f * move rump_vopwrite_fault() into history - we now support the file 
system faulting in pages if it does e.g. fragment reallocation
* get rid of rumpvm_findpage() and always use uvm_pagelookup()
* determine a vnode's cleanness by flagging it as being on the work
  list if we "take" a write fault and removing it from the worklist
  once pages are flushed.  There is no work list here, but at least
  there is symmetry with the kernel.

c3bc94628d Play catchup with ufs/ffs changes: compile subr_specificdata.c 
and emulate kmem_foo() to support the prior.

36c0b176cc Fix it a bit & wait for the dust to settle. Also, enable UBC by default. 
ffs in userspace on top of puffs/p2k/rump is now stable enough to
host a make -j4 kernel build (well, at least my kernel build ...
but, yes, I am currently running that kernel on my desktop)

58b908ae12 Flush file's pages in inactive (they'll still be kept in the kernel 
page page if it's enabled).  This very easily takes care of memory
management problems except for large files.

37698f56d6 Enable lfs in r/o mode, i.e. does not start lfs_clean-nerd and do 
any real trickery.  Unfortunately this was the easy part; r/w
support is going to make ascending naked, blind, illiterate, without
food and as an atheist look trivial.

dfeea3487b Don't need to use MNT_FORCE here (my original test image was a bit

24c0b6d0d0 Provide rump_getvninfo() and use that in libp2k_lookup() to avoid an 
extra getattr for stuff the file system already cached in the vnode.

804db68101 Make genfs_islocked return always 1 instead of 0. But these should 
really get tracked ...

427705465b Provide rumpmachine bswap.h, which makes bswapxx() call rumpuser 
directly instead of relying on a symbol in rumpkern.  I would like
to make it call the libc symbol directly, but I don't currently know
how to make it do that MI.

Makes hfs work (on i386), as it avoids endless recursion in bswap64().
Thanks to dillo for the image!

bbae7f4e94 Add hfs. Untested, as I couldn't find a hfs+ image for testing, 
so one would be appreciated.  At least it works enough to tell me
this:
