Julian GanzandAlex Bennée 14e1f3186c target/avr: call plugin trap callbacks 
We recently introduced API for registering callbacks for trap related
events as well as the corresponding hook functions. Due to differences
between architectures, the latter need to be called from target specific
code.

This change places the hook for AVR targets. That architecture appears
to only know interrupts.

Philippe Mathieu-Daudé 482869ca84 accel/tcg: Name gen_goto_tb()'s TB slot index as @tb_slot_idx 
tcg_gen_goto_tb() takes an unsigned index to the TB slot (0 or 1).
Declare the argument as unsigned and rename it as @tb_slot_idx
(which is more descriptive than @n) on all targets.

Paolo Bonzini 602d5ebba2 treewide: clear bits of cs->interrupt_request with cpu_reset_interrupt() 
Open coding cpu_reset_interrupt() can cause bugs if the BQL is not
taken, for example i386 has the call chain kvm_cpu_exec() ->
kvm_put_vcpu_events() -> kvm_arch_put_registers().

Igor MammedovandPaolo Bonzini 87511341c3 add cpu_test_interrupt()/cpu_set_interrupt() helpers and use them tree wide 
The helpers form load-acquire/store-release pair and ensure
that appropriate barriers are in place in case checks happen
outside of BQL.

Use them to replace open-coded checkers/setters across the code,
to make sure that barriers are not missed.  Helpers also make code a
bit more readable.

Richard Henderson 981f2beb16 target: Use cpu_pointer_wrap_uint32 for 32-bit targets 
M68K, MicroBlaze, OpenRISC, RX, TriCore and Xtensa are
all 32-bit targets.  AVR is more complicated, but using
a 32-bit wrap preserves current behaviour.

Combine 3 different pointer returns into one structure return.

Include a cflags field in TCGTBCPUState, not filled in by
cpu_get_tb_cpu_state, but used by all callers.  This fills
a hole in the structure and is useful in some subroutines.
