Since the only caller of page_unprotect() which might cause it to
need to call cpu_resume_from_signal() is handle_cpu_signal() in
the user-mode code, push the longjump handling out to that function.
Since this is the only caller of cpu_resume_from_signal() which
passes a non-NULL puc argument, split the non-NULL handling into
a new cpu_exit_tb_from_sighandler() function. This allows us
to merge the softmmu and usermode implementations of the
cpu_resume_from_signal() function, which are now identical.

The is_cpu_write_access argument is always 0, remove it.

Remove them from the sundry exec-all.h header, since they are only used by
the TCG runtime in exec.c and user-exec.c.

The exec.c and translate-all.c radix trees are quite different, and
the exec.c one in particular is not limited to the CPU---it can be
used also by devices that do DMA, and in that case the address space
is not limited to TARGET_PHYS_ADDR_SPACE_BITS bits.
We want to make exec.c's radix trees 64-bit wide. As a first step,
stop sharing the constants between exec.c and translate-all.c.
exec.c gets P_L2_* constants, translate-all.c gets V_L2_*, for
consistency with the existing V_L1_* symbols. Though actually
in the softmmu case translate-all.c is also indexed by physical
addresses...
This patch has no semantic change.
