Impact: build fix
The APIC code rewrite in the x86 tree broke the x86/mce branch:
arch/x86/kernel/cpu/mcheck/threshold.c: In function ‘mce_threshold_interrupt’:
arch/x86/kernel/cpu/mcheck/threshold.c:24: error: implicit declaration of function ‘ack_APIC_irq’
Also tidy up the file a bit while at it.

Impact: minor bugfix
The threshold handler on AMD (and soon on Intel) could be theoretically
reentered by the hardware. This could lead to corrupted events
because the machine check poll code assumes it is not reentered.
Move the APIC ACK to the end of the interrupt handler to let
the hardware avoid that.

Impact: cleanup; preparation for feature
The mce_amd_64 code has an own private MC threshold vector with an own
interrupt handler. Since Intel needs a similar handler
it makes sense to share the vector because both can not
be active at the same time.
I factored the common APIC handler code into a separate file which can
be used by both the Intel or AMD MC code.
This is needed for the next patch which adds an Intel specific
CMCI handler.
This patch should be a nop for AMD, it just moves some code
around.
