Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.

jermar – 15 file(s) modified
The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.

Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.

Rename IPC_M_DATA_SEND to IPC_M_DATA_WRITE. Now, when we also add
IPC_M_DATA_READ, it will not clash and cause confusion with userspace wrappers
such as ipc_data_receive(). Rename the forementioned wrappers to
ipc_data_write_send(), ipc_data_write_receive() and ipc_data_write_deliver().

Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().

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.
