When you don't use !E or !I but only !F, then it's very easy to miss
including some functions, structs etc.  in documentation.  To help
finding which ones were missed, allow printing out the unused ones as
warnings.

For example, using this on mac80211 yields a lot of warnings like this:

  Warning: didn't use docs for DOC: mac80211 workqueue
  Warning: didn't use docs for ieee80211_max_queues
  Warning: didn't use docs for ieee80211_bss_change
  Warning: didn't use docs for ieee80211_bss_conf

when generating the documentation for it.

- getcwd returns path without a slash at the end, add the slash
- add KBUILD_SRC env support, so that we can specify path for
  kernel (to know where scripts/kernel-doc resides) and SRCTREE
  (for searching files referenced in .tmpl) separately

[v2]
- use KBUILD_SRC instead of a newly introduced environment variable
