bug#19390: 25.0.50; `package-activate' is too slow

In retrospect, the cleanest way to do do all this would have been to
build this reloading into `require' and `provide' (something would
have to be done with autoloads too). Then package.el could go back to
not worrying about it, and most of this discussion would be moot.

The only problem I see with this is that we might have (much smaller)
performance issues with `package-initialize` again, since `require'
has no way of knowing whether it was invoked from inside
`package-initialize'. The issue would be smaller because handling it
inside `require' could be done more intelligently.
