bug#11915: libraries that don't provide a feature or the wrong one

[Jonas Bernoulli]

* in the emacs-24 branch:

bug-reference.el and map-ynp.el do not provide a feature.
misearch.el provides `multi-isearch' instead of `misearch'.

userlock.el, patcomp.el, forms-d2.el and forms-pass.el also
don't provide a feature but it seems this intentional.
However I think they then should not appear in `packages-builtins'.
The last two could possibly be added to the forms package.

* in the elpa branch:

markchars.el does not provide a feature.
