VFS rewrite:
- add new VFS methods
- VFS_NODE for getting VFS node for a file descriptor
- VFS_OPEN_NODE for opening an i-node directly
- VFS_DEVICE for getting the underlying device of a file (if any)
- VFS_SYNC for syncing buffers
- L_OPEN flag is set to underlying filesystem in VFS_LOOKUP when opening a file to support initialization (if any)
- VFS_CLOSE is now propagated to underlying filesystem to support cleanup (if any) |

Hold the namespace rwlock during the entire operation of vfs_mount_internal().
Get rid of rootfs futex, which is not needed anymore.
Do not instantiate VFS node for the mounted root if the mount failed. |

Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP. |

Support mount options.
Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option. |

support for pending (blocking) mounts (waiting for the presence of the filesystem implementation)

Add reference to the mounted FS root.
This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir(). |

Fix the VFS protocol so that the client can determine that VFS_MOUNT failed due
to a request to mount an unregistered file system. |

Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close(). |

Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function. |

Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future. |

Separate creation of a TMPFS node and its linking in the file system name space.

Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag). |
