staging: lustre: headers: move swab functions to new header files 

Create headers for pack_generic.c and llog_swab.c
Reference only where needed. This separates out
the kernel only code from lustre_idl.h that is
an UAPI header.

* (see lustre_msg_swabbed() below).
*
* Each wire type has corresponding 'lustre_swab_xxxtypexxx()' routines
* are implemented in ptlrpc/lustre_swab.c. These 'swabbers' convert the
* type from "other" endian, in-place in the message buffer.
*
* A swabber takes a single pointer argument. The caller must already have
* verified that the length of the message buffer >= sizeof (type).
*
* For variable length types, a second 'lustre_swab_v_xxxtypexxx()' routine
* may be defined that swabs just the variable part, after the caller has
* verified that the message buffer is large enough.
