-adjust for new libs, programs and source files
-replace generated config.h and mkver
-add Frederick Bruckman's awk implementation of "ntptrace" as a
replacement for the perl program in the original tree
contents of that header (the only file that includes it compiles to the
same object code on multiple architectures with or without including
<ieeefp.h>), so remove all references to it.
Fix sent to NTP maintainers - they will probably implement this change
after the immenient 4.1.0 release, but don't want to change it so close
to the release date.
