gdbstub: Fix gdb_register_coprocessor() register counting

Commit a0e372f0c49ac01faeaeb73a6e8f50e8ac615f34 reorganized the register
counting for GDB. While it seems correct not to let the total number of
registers skyrocket in an SMP scenario through a static variable, the
distinction between total register count and 'g' packet register count
(last_reg vs. num_g_regs) got lost among the way.

Fix this by introducing CPUState::gdb_num_g_regs and using that in
gdb_handle_packet().

qom: Introduce instance_post_init hook

This will allow classes to specify a function to be called after all
instance_init functions were called.

This will be used by DeviceState to call qdev_prop_set_globals() at the
right moment.

target-arm: Implement 'int' loglevel

The 'int' loglevel for recording interrupts and exceptions
requires support in the target-specific code. Implement
it for ARM. This improves debug logging in some situations
that were otherwise pretty opaque, such as when we fault
trying to execute at an exception vector address, which
would otherwise cause an infinite loop of taking exceptions
without any indication in the debug log of what was going on.

target-arm: Make IRQ and FIQ gpio lines on the CPU object

Now that ARMCPU is a subclass of DeviceState, we can make the
CPU's inbound IRQ and FIQ lines be simply gpio lines, which
means we can remove the odd arm_pic shim.

We retain the arm_pic_init_cpu() function as a backwards
compatibility shim layer so we can convert the board models
to get the IRQ and FIQ lines directly from the ARMCPU
object one at a time.
