Subject: libtrivfs: improve the mig mutator functions

Previously, the mig mutator functions were in migsupport.c, preventing
them from being inlined into the mig-generated server functions.  Put
them in mig-decls.h instead.  Rename mutations.h to mig-mutate.h.
This is the naming convention used for pflocal.

* libtrivfs/fsmutations.h: Rename to mig-mutate.h, adopt imports.
* libtrivfs/Makefile: Adopt accordingly.
* libtrivfs/migsupport.c: Rename to mig-decls.h.
* libtrivfs/trivfs.h: Move dynamic classes/buckets declarations to
mig-decls.h, remove superfluous imports.
* exec/execmutations.h: Fix import.
* pfinet/mig-mutate.h: Likewise.
* trans/Makefile: Likewise.
