677ef6230b replace spinlock by QemuMutex.
spinlock is only used in two cases:
  * cpu-exec.c: to protect TranslationBlock
  * mem_helper.c: for lock helper in target-i386 (which seems broken).

It's a pthread_mutex_t in user-mode, so we can use QemuMutex directly,
with an #ifdef.  The #ifdef will be removed when multithreaded TCG
will need the mutex as well.

f08b617018 softmmu: introduce cpu_ldst.h
This will collect all load and store helpers soon.  For now
it is just a replacement for softmmu_exec.h, which this patch
stops including directly, but we also include it where this will
be necessary in order to simplify the next patch.

0f590e749f softmmu: commonize helper definitions
They do not need to be in op_helper.c.  Because cputlb.c now includes
softmmu_template.h twice for each size, io_readX must be elided the
second time through.

2ef6175aa7 tcg: Invert the inclusion of helper.h
Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h.  This
minimizes the files that must be rebuilt when changing the macros
for file N.

7510454e3e cpu: Turn cpu_handle_mmu_fault() into a CPUClass hook
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.
