95a18d20b9 Hide struct puffs_usermount from the rest of the world and provide 
accessors for interesting data in it.  Namely, you can now get
pu->pu_privdata with puffs_getspecific(), pu->pu_pn_root with
puffs_set/getroot() and pu->pu_maxreqlen with puffs_getmaxreqlen().

6b7023f08f * support nodetofh and fhtonode callbacks 
* use new signature of node_readdir

2df275c4cd va->va_mode doesn't contain the full argument to the mknod() system call, 
so introduce puffs_addvtype2mode() and use that in null.c to generate the
proper syscall argument

d695eff80f Create in-memory nodes only per unique inode, not unique pathname. 
Solves problem with e.g. cache coherency of hardlinked files.

76fead3a3e Readlink should place the length of the link (without terminating 
nul) in the length field.  Make it so.

a32e39e624 * get rid of the holy kernel-given ISDOTDOT, and instead define a 
macro which does strcmp against ".." and (the untranslated)
  componentname
* make PUFFS_FLAG_BUILDPATH build paths also if dotdot is the case,
  and adapt the regular path objects to this
* make nullfs lookup readable because we can now get rid of dotdot
  processing there

9715dfff81 If we can't set the attributes when making the directory, use rmdir to 
remove the directory, not unlink.

05861b929d Checkpoint some more work in progress: for the benefit those file 
system backends which operate purely based on paths, push out more
path management into the library and make path management more
abstract: enable a file system to define a bunch of path management
callbacks, which are used by the framework.  Management of normal
/this/is/a/path type paths is provided by the library.

b599bb507d * do the l-variations of syscalls, since some nodes are symlinks 
* truncate only regular files to set size
* do the chmod()-dance for cache flush to now write-protected files
  until I can think of a nicer way to solve this

e639bec8c2 Add preliminary code for a nullfs layer, which can be used to mount 
a directory hierarchy to another point, just like with the kernel
nullfs.  This is not really a layering scheme yet, but it should
evolve into one.  Currently it can just be used to do 1:1 mapping.
