* add private function get_system_revision() for accessing the
revision string
* adjust uname to use get_system_revision

at all and, since there can be multiple IO-APICs, we need to do the
enumeration again in the kernel anyway. Also only set ioapic_phys the first
time we encounter an IO-APIC object as it looks cleaner when we arrive at the
first IO-APIC default address.
* Therefore we don't have to worry about already mapped IO-APICs when
enumerating them in the kernel.
* Also remove the mapping function that is now not used anymore.
* We still use the ioapic_phys field of the kernel args to determine whether
there is an IO-APIC at all to avoid needlessly doing the enumeration again.
This fixes multi IO-APIC configurations, because before we would indeed map
the last IO-APIC listed in the MADT, but then in the kernel assumed we mapped
the first one. We'd end up with mapping the last listed IO-APIC twice and the
first IO-APIC never, always programming the last one when we actually targetted
the first one.

Fixed typo on previous commit of expat.
Note that this moves the location of openssl, so other packages that
make use of openssl may or may not require rebuilding as well.

mark the ISA interrupts as unusable and then use ioapic_is_interrupt_available
to determine if that vector is possibly taken by an IO-APIC. If IO-APICs are
not used, this will simply always return false, leaving all vectors free for
MSI use.
* The msi_init() now has to be done after a potential IO-APIC init, so it is now
done after ioapic_init() instead of inside apic_init().
* Add apic_disable_local_ints() to clear the local ints on the local APIC once
we are in APIC mode (i.e. the IO-APIC is set up and we don't need the external
routing anymore).

we got. If the routing is possible with the limited IO-APICs everythings good,
if not we will simply fail at the routing preparation stage where we can still
fall back gracefully. This makes things a bit more error resilient.

number. This accounts for possible gaps in the IO-APIC GSI mappings. Since most
of the time there will be only a single IO-APIC the extra overhead is relatively
small.

the same for the first IO-APIC in the bootloader (also using the MADT), but
here we can use the ACPI module. The enumerated IO-APICs are added to the list
and should be usable from there on. For lack of hardware I wasn't able to really
test that though.

effects.
* Some cleanup.

functional change intended.
* Use an appropriately sized sLevelTriggeredInterrupts for each controller type.
This also fixes an out of bound access for IO-APICs with more than 32 entries
and also returns the right mode in such cases.

* changes next_log to their actual type instead of void*
* the field this_phy now includes the item type, it simplifies things.
* isochronous transfer descriptors are linked in the periodic frame list first,
and points to existing interrupt transfer descriptors.
This is still work in progress. Yet it's worth committing as it doesn't seem to
have impacts, and is required for the UVC SoC project. Tested basically with
usb_webcam to receive UVC stream headers.

* the length of the sHaikuRevision character array symbol needs to be set explicitly,
as using either _SYS_NAMELEN or sizeof(utsname::version) will only return the values
for the host, which may not match ours, thus potentially causing problems when using
sHaikuRevision
* add headers/private/system_revision.h which defines SYSTEM_REVISION_LENGTH to 128
* adjust definitions of sHaikuRevision in libroot and kernel accordingly
utsname::version is shorter than SYSTEM_REVISION_LENGTH, but that doesn't cause any harm
until we have indeed switched to a DVCS (in which case longer revision strings will be
cut off by 'uname').

already. This allows to detect invalid settings before starting to enable
IRQ routing and therefore allows to gracefully fall back to PIC mode on error.
* Actually read the number of IO-APIC entries before using that number in
routing preparation.

support yet (but are relatively rare anyway).
