Thomas Veerman ddbdca6cdb Add support for survival of crashed FSs 
When an FS crashes, VFS will clean up resources tied to that FS:
 - Pending requests to the FS are canceled (i.e., fail with EIO)
 - Threads waiting for a reply are stopped (i.e., fail with EIO)
 - Open files are marked invalid. Future operations on a file descriptor
   will cause EBADF errors.
 - vmnt entry is cleared, so in-flight system calls that got past the
   file descriptor check but not yet talking to the crashed FS, will
   fail with EIO.
 - The reference counter of the mount point is decreased, effectively
   removing the crashed FS from the file system tree. Descendants of
   this part of the tree are unreachable by means of a path, but can
   still be unmounted by feeding the block special file to unmount(2).

This patch also gets rid of the "not a known driver endpoint" messages
during shutdown.
