RFC: deprecate CALLOUT_MPSAFE

[Jung-uk Kim]

CALLOUT_MPSAFE has lost its meaning since r141428, i.e., more than ten
years for CURRENT. However, it is continuously misused as mpsafe
argument for callout_init(9). This patch cleans up callout_init()
calls and deprecate the flag.

Any objections?

FYI, I decided to go ahead and commit this patch. Then, we will
remove the mpsafe argument from callout_init() as glebius suggested.
