Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only. |

newly introduced type and fix formatting in futex.c. |

/trunk/uspace/ |
Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.
Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes. |

VFS work.
During VFS_REGISTER, use strncmp() instead of strcmp().
Add one excessive convenience byte to vfs_info.name to support the
above-mentioned change. In case the fs name spans all available
characters, make sure this convenience byte is zero. |

A lot of more VFS prototyping.
VFS_OPEN gets reasonably complete, fix a limitation that prevented file
structures from being shared by multiple file descriptors, add functions for
file descriptor management, introduce unlink_futex and two new VFS operations
VFS_UNLINK and VFS_RENAME. |

VFS work.
Allocate the open filess array dynamically and protect access to it via a
per-connection futex. Defer its allocation until the client makes a first
VFS_OPEN request.
Actually call vfs_mount() and vfs_open(), respectively, when the VFS_MOUNT and
VFS_OPEN requests, respectively, are received from the client. |

VFS work.
Introduce the notion of VFS_PAIR which corresponds to a file system instance,
and VFS_TRIPLET, which corresponds to a file system node. Separate vfs_triplet_t
and vfs_node_t as the former one is the stateless counterpart of the latter. |
