List wait events in alphabetical order

Browse Source 
This changes the documentation, and the related structures so as
everything is consistent.

Some wait events were not listed alphabetically since their
introduction, others have been added rather randomly.  Keeping all those
entries in order helps in maintenance, and helps the user looking at the
documentation.

Backpatch-through: 10, only for the documentation part to avoid an ABI
breakage.
