Added x2APIC support. * Mostly useful for virtualization at the moment. Works in QEmu. * Can be enabled by safemode settings/menu. * Please note that x2APIC normally requires use of VT-d interrupt remapping feature on real hardware, which we don't support yet.

* Introduce {reserve|allocate|free}_io_interrupt_vectors() that can generically be used to mark certain io interrupt vectors as reserved and to allocate from the still free ones. It is a kernel private API for now though. * Make the MSI code use that functionality instead of implementing its own which slims it down considerably and also removes quite a bit of hardcoded knowledge about the interrupt layout that didn't really belong there. * Mark the various in-use interrupts as reserved from the components that actually know about them (PIC, IO-APIC, SMP, APIC timer and interrupt setup). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@42832 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Add code to allocate and free interrupt vectors for message signaled interrupts (MSI). * Add the remaining IDT entries and redirection functions in the interrupt code. * Make the PIC end_of_interrupt() return a result to indicate whether the vector was handled by this PIC. If it isn't we now issue a apic_end_of_interrupt() in the assumption of apic local interrupt, MSI or IPI. This also removes the need for the gUsingIOAPIC global and doing manual apic_end_of_interrupt() calls in the SMP and timer code. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36221 a95241bf-73f2-0310-859d-f6bbb57e9c96

Seperate the generic (local) APIC stuff into it's own file and use it from the other places where previously the same functionality was duplicated. Also seperated the header which was originally arch_smp.h into apic.h and arch_smp.h again as some of it is MP and not actually APIC. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36182 a95241bf-73f2-0310-859d-f6bbb57e9c96
