caa4039ced Code provision for PowerPC 64 MMU model support.

8b67546f65 More PowerPC target cleanups: 
- remove unuseful historical macros and definitions
- fix comments (bugs and cosmetics)

d9d7210c7d Fix PowerPC 32 emulation on 64 bits hosts: 
we can use 64 bits registers but not pretend page is 1kB long
As it seems most Linux programs assume page-size is 4kB, never allow
1kB pages for user-mode only emulation.

3608160206 Coding style fixes in PowerPC related code (no functional change): 
- avoid useless blanks at EOL.
- avoid tabs.
- fix wrapping lines on 80 chars terminals.
- add missing ';' at macros EOL to avoid confusing auto-identers.
- fix identation.
- Remove historical macros in micro-ops (PARAM, SPARAM, PPC_OP, regs)

4710357290 New model for PowerPC CPU hardware interrupt events: 
move all PowerPC specific code into target-ppc/helper.c to avoid polluting
the common code in cpu-exec.c. This makes implementation of new features
(ie embedded PowerPC timers, critical interrupts, ...) easier.
This also avoid hardcoding the IRQ callback in the OpenPIC controller,
making it more easily reusable and allowing cascading.
