Kernel's ipc_data_t and uspace's ipc_call_t must be in sync.
This commit fixes a problem introduced in revision 3362, when
ipc_data_t was enlarged by the caller_phone member. This resulted
in sys_ipc_wait_for_call() passing larger structure to uspace
than requested, leading to a random damage of userspace memory. |

Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly. |

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(). |

Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async. |

Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync. |

VFS work.
Added mandatory VFS_LOOKUP
Handling of VFS_REGISTER request should be now more or less complete.
Added code that inserts the new fs_info structure into the list of registered
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. |

Implement a new mechanism for copying data between two address spaces based on
IPC. New system method IPC_M_DATA_SEND is introduced. The implementation is
generic and does not make use of any possible architecture optimizations such as
direct copy from one address space to another. |

Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code. |

For the sake of clarity, get rid of negative INR for virtual interrupts.
This way, the code can hurt performance on systems where the non-negative klog INR overlaps
with a frequently used INR such as system clock on amd64 and ia32. |

Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile. |

Prototypical implementation of new IRQ redirector in sparc64.
The new code can support shared IRQs in kernel (and multiple IRQs per device).
Userspace support is yet to be written.
The only architecture that uses this code is actually sparc64 only. |
