Note that while such functions may exist both for *-user and softmmu,
only *-user uses the CPUState hook, while softmmu reuses the prototype
for calling it directly.

This patch uses inbound GPIO lines (IRQ and FIR) for
interrupts instead of using the old pic_cpu method,
which doesn't correspond to real hardware.
This creates the CPU's inbound IRQ and FIR GPIO lines and
updates the Microblaze boards to use this new method.

The functions cpu_clone_regs() and cpu_set_tls() are not purely CPU
related -- they are specific to the TLS ABI for a a particular OS.
Move them into the linux-user/ tree where they belong.
target-lm32 had entirely unused implementations, since it has no
linux-user target; just drop them.

Use it for all targets, but be careful not to pass invalid CPUState.
cpu_single_env can be NULL, e.g. on Xen.

This removes a global per-target function and thus takes us one step
closer to compiling multiple targets into one executable.
It will also allow to override the interrupt handling for certain CPU
families.

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before

cpu_{save,load} were no-ops, so de facto it is unmigratable and no
backwards compatibility to keep. Therefore mark the MicroBlazeCPU as
unmigratable at device level the QOM way and suppress "cpu_common"
VMState registration by dropping CPU_SAVE_VERSION.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"

Commit 9b9a970a23625de4ae6b7461906a9a0d98d3ca95
(target-lm32/microblaze: Typedef struct CPU{MB,LM32}State)
introduced necessary typedefs for cpu_mmu_index() and mmu.h
respectively.
On some GCC versions this leads to "error: redefinition of typedef".
Drop the original typedef to hopefully fix the build.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations. This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently. Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.
Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality. I have removed
such blocks for the appropriate targets in this patch.
