Remove the dummies from the C code and implement them in assembly,
due to the label referencing issues with the fault handler.
This code is ripe for optimisation, my ARM assembly is pretty
basic ;)
Does work though, and gets us one step closer to a full arch.
As noted during BeGeistert and today again by kallisti5, there's a
Pentium reference in the ARM bootloader code.
Correct the message to something more appropriate....
Thanks to Rene for the suggestion ;)
This is to make sure all ARM platforms will benefit from planned work on this
MMU/CPU code. The less code duplicated, the better.
Compile-tested for all supported ARM platforms

* Read/Write up to 1024x1024 icon sizes.
* All build-in icon sizes available as pages in ShowImage.
* Support only 32-bit icon colors (rgb32 and rgba32) now.
This also implements the fault handler correctly now, and cleans up the
exception handling. Seems a lot more stable now, no unexpected panics or
faults happening anymore.
This will generate asm_offsets.h which makes our assembly code
easier to maintain by preventing hardcoded offsets for fields within structures.

- BreakpointTableModel now encapsulates both breakpoints and watchpoints.
- Extended BreakpointView and TeamWindow to handle enable/disable/removing
watchpoints as well.
This comes from a similar patch in FreeBSD r234666 but does the check
and acknowledge in the case where we don't have any other interrupts.
Since the interrupt isn't used it is never unmasked and therefore the
check against the interrupt mask will always fail if the TWSI IRQ is
the only interrupt that happened. In that case an interrupt storm would
be triggered that lasts until any other valid interrupt comes along, is
handled and both are acknowledged.
This may help with #8454 on some cards that exhibit the spurious TWSI
IRQs.
Since we now implement HAIKU_CHECK_DISABLE_INTERRUPTS there is no need
to do it again in the interrupt handler. Further, store and carry over
the interrupt status from the hook to the interrupt handler as that is
cleaner and just in case reading the register somehow clears it. May
help with #8454.
This gets basic watchpoint support working. Right clicking on a variable
and picking Watch now opens a prompt with the inferred address, size
and watch type for the user to adjust.
Still needs some work to get them to show/be modifiable in the breakpoints
tab and to get them to respect architectural restrictions (i.e. on x86 we
can realistically only do 2 hardware watchpoints and those are restricted
to write watch), at least until we support software emulated watchpoints.
