Rename libvex_emwarn.h to libvex_emnote.h and fix all 
#include's. The renaming of guest_EMWARN, VexemWarn etc will
be done in a followup patch.
The rationale for all this is that we want to reuse the existing
machinery for emulation warnings also for emulation failures.
And that calls for some kind of neutral naming scheme.
