new module 'clean-temp-simple'

[Bruno Haible]

This series of patches splits the module 'clean-temp' into two modules:
  - clean-temp-simple, under LGPLv2+,
  - clean-temp, still under GPL.

I am the sole author of lib/clean-temp-simple.c, hence I can do this.
(The contributions to lib/clean-temp.c by Eric Blake and John Darrington
are still in lib/clean-temp.c, not moved to lib/clean-temp-simple.c.)
