72393e3d80 Fix fuse so that stale buffer cache data isn't read.
When I/O on a file under fuse is switched from buffered to DIRECT_IO,
it was possible to read stale (before a recent modification) data from
the buffer cache. This patch invalidates the buffer cache for the
file to fix this.

d9454fab30 - Current caching mode is completely broken because it simply relies
on timing of the operations and not real lookup, bringing too many
  false positives. Remove the whole mechanism. If it needs to be
  implemented, next time it should really be done in the proper way.
- Fix VOP_GETATTR() in order to cope with userland bugs that would
  change the type of file and not panic. Instead it gets the entry as
  if it is not existing.

5fe580195f Import a FreeBSD port of the FUSE Linux module.
This has been developed during 2 summer of code mandates and being revived
by gnn recently.
The functionality in this commit mirrors entirely content of fusefs-kmod
port, which doesn't need to be installed anymore for -CURRENT setups.

In order to get some sparse technical notes, please refer to:
http://lists.freebsd.org/pipermail/freebsd-fs/2012-March/013876.html

or to the project branch:
svn://svn.freebsd.org/base/projects/fuse/

which also contains granular history of changes happened during port
refinements. This commit does not came from the branch reintegration
itself because it seems svn is not behaving properly for this functionaly
at the moment.
