Rewrite rest of multiboot info parsing to C. |

The ia32-specific boot code is written completely in assembly for no reason. Start fixing this. For now rewrite the copying of multiboot info to C. |

kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone() |

kernel memory management revisited (phase 1): proper support for zone flags
- the zone_t structures are now statically allocated to be easily available
- the locking scheme was simplified
- new flags for non-available zones were introduced
- FRAME_LOW_4_GiB flag is removed, the functionality will be eventually reimplemented using a generic mechanism |

The kernel i8042 driver should be instance-neutral. |

This is the evil commit. In particular, it does:
- introduces more powerful pseudo code for userspace IRQ top-half handlers
- changes the internals of IRQ dispatching
- simplifies the kernel's i8042 driver
- adapts the uspace i8042 driver to make use of the new pseudocode
- breaks all other architectures except ia32
- breaks almost all existing drivers
- breaks switching between uspace and kernel drivers |

IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument. |

Introduce a more platform-neutral name for programmed I/O.
The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers. |

The IA-32 manual is very secretive about the fact that the SYSENTER instruction
disables interrupts (I found only one evidence of this in the instruction's
pseudo code). The sysenter_handler needs to reenable the interrupts in order to
preserve the preemptive nature of the kernel. |

Replace either with built-in functions or with generic functions. |

Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem. |
