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. |

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. |

Modify vfs_lookup_internal() to be able to work with an alternate root. This
will be useful for VFS_MOUNT support.

path has been looked up. |

VFS work.
Upon FS registration via VFS_REGISTER, the client is assigned a unique file
system handle. When generating the VFS_LOOKUP request in VFS, we also need to
pass the device handle. Add function to transform file system handle to phone.
Implement basic multi-call VFS request serialization on VFS side. |

Added mandatory VFS_LOOKUP
Handling of VFS_REGISTER request should be now more or less complete.

filesystems and creates a callback connection to the client FS. |

VFS work.
Now, each VFS connection fibril will accept requests in a loop. The idea is that
each connection will be potentially reused for multiple requests before it is
closed by the server.
More VFS_REGISTER bits. Make use of the IPC_M_DATA_SEND wrappers introduced in
the previous commit.
Add enum members for more VFS operations. |
