Introduce VFS_IN_FSTAT and VFS_OUT_STAT.
Provide libc fstat() and devfs_stat().
This functionality replaces VFS_IN_NODE
and VFS_IN/OUT_DEVICE. FAT and TMPFS
still do not implement this and VFS_IN_STAT
and stat() need implementation as well. |

Make VFS use the new synchronization for fibrils. Now there should be no (or
only secondary) fibril serialization. Code reorganized not to hold the phone
lock during async_wait_for() in most cases. Tested on ia32. On amd64, VFS
crashes, but I think it is an unrelated problem. |

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. |

VFS_LOOKUP. |

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. |
