libpager: fix receiver lookups

Previously, the receiver lookup was done manually in all the server
functions.  Use mig translator functions instead.

* libpager/mig-decls.h: New file.
* libpager/mig-mutate.h: Likewise.
* libpager/Makefile (MIGSFLAGS): Include mig-mutate.h.
* libpager/chg-compl.c: Fix receiver lookups.
* libpager/data-request.c: Likewise.
* libpager/data-return.c: Likewise.
* libpager/data-unlock.c: Likewise.
* libpager/lock-completed.c: Likewise.
* libpager/object-init.c: Likewise.
* libpager/object-terminate.c: Likewise.
* libpager/stubs.c: Likewise.
* libpager/seqnos.c (_pager_update_seqno): Move the actual
functionality...
(_pager_update_seqno_p): ... into a new function that can be called
with a pointer to struct pager.
* libpager/priv.h (_pager_update_seqno_p): New declaration.
