openpic: IRQ_check: search the queue a word at a time

Search the queue more efficiently by first looking for a non-zero word,
and then using the common bit-searching function to find the bit within
the word. It would be even nicer if bitops_ffsl() could be hooked up...

openpic: move IACK to its own function

Besides making the code cleaner, we will need a separate way to access
IACK in order to implement EPR (external proxy) interrupt delivery.

openpic: fix CTPR and de-assertion of interrupts

Properly implement level-triggered interrupts by withdrawing an
interrupt from the raised queue if the interrupt source de-asserts.
Also withdraw from the raised queue if the interrupt becomes masked.

When CTPR is written, check whether we need to raise or lower the...

openpic: always call IRQ_check from IRQ_get_next

Previously the code relied on the queue's "next" field getting
set to -1 sometime between an update to the bitmap, and the next
call to IRQ_get_next. Sometimes this happened after the update.
Sometimes it happened before the check. Sometimes it didn't happen...

Revert "openpic: Accelerate pending irq search"

This reverts commit a9bd83f4c65de0058659ede009fa1a241f379edd.

This counting approach is not robust against setting a bit that
was already set, or clearing a bit that was already clear. Perhaps
that is considered a bug, but besides the lack of any documentation...

openpic: use standard bitmap operations

Besides the private implementation being redundant, namespace collisions
prevented the use of other things in bitops.h.

Serialization does get a bit more awkward, unfortunately, since the
standard bitmap operations are "unsigned long" rather than "uint32_t",...

openpic: add some bounds checking for IRQ numbers

The two checks with abort() guard against potential QEMU-internal
problems, but the EOI check stops the guest from causing updates to queue
position -1 and other havoc if it writes EOI with no interrupt in...

openpic: fix sense and priority bits

Previously, the sense and priority bits were masked off when writing
to IVPR, and all interrupts were treated as edge-triggered (despite
the existence of code for handling level-triggered interrupts).

Polarity is implemented only as storage. We don't simulate the...
