  Log Message:
  -----------
  curl: do not use aio_context_acquire/release

Now that all bottom halves and callbacks take care of taking the
AioContext lock, we can migrate some users away from it and to a
specific QemuMutex or CoMutex.

Protect BDRVCURLState access with a QemuMutex.

  nfs: do not use aio_context_acquire/release

Now that all bottom halves and callbacks take care of taking the
AioContext lock, we can migrate some users away from it and to a
specific QemuMutex or CoMutex.

Protect libnfs calls with a QemuMutex.  Callbacks are invoked
using bottom halves, so we don't even have to drop it around
callback invocations.

  Log Message:
  -----------
  tests-aio-multithread: use atomic_read properly

nodes[id].next is written by other threads.  If atomic_read is not used
(matching atomic_set in mcs_mutex_lock!) the compiler can optimize the
whole "if" away!
