New loplugin:oslendian
...to catch new places where defined'ness of OSL_BIG/LITENDIAN would be checked without osl/endian.h being included; cf. e2f08f9def0869460ad38a1c2adb450778290f6e "connectivity, sc: add missing #include <osl/endian.h>" and 2b14fb3a4f92b928f0a5fc536c6a5f4a6e51a9b8 "cppcanvas, oox: add missing #include <osl/endian.h>". Change-Id: I167c8916a01391b7dacad7325153ccf35d3ba9dc
