waf, git, EPOCH, version strings, ...

One way is to run a script that makes a header file with version and EPOCH 
info.  I'm not enough of a waf wizard to be able to do it without some 
research, but somebody already makes ntpd/version.h so I'm pretty sure I 
could do it with enough work.

The other way would be to get -DEPOCH=xx on the build line for ntpd.o

That's putting something into config.h

I want to put it on the cc line that compiles ntpd.c

Right.  It's in config.h  That's what we have to fix if we want to get decent 
version strings.
