Submitted by someone who thinks he's called "Daper": 

Fix bug #15013: Wrong use of PPICLAIM (kernel: ppdev0: claim the
port first)

* par.c: don't claim/release here (thus win_ppdev.h not needed
anymore)
* ppi.c: claim/release here.
* freebsd_ppi.h: ppi_claim/ppi_release now take an fd as parameter.
* solaris_ecpp.h: (Ditto.)
* linux_ppdev.h: (Ditto.)  (Also add copyright.)
* win_ppdev.h: Not needed anymore, remove.
